Proximity™ Series PLS is used to indicate level status in pneumatic
conveying systems.
Mercoid® pump controller with level transmitter control pumps in
wastewater lift stations.
Pneumatic conveying systems use air to transport powder and dry bulk solids through
conveying lines. The air is pressurized by positive pressure or vacuum to move the
product through the lines into and out of silos, transporters, and receivers. Typical
applications have high and low level indication in the storage bins to control the flow
of product in or out. The PLS is perfect for level use in these storage bins. It has a
rotating paddle that is inserted into the bin. As the product level builds up in the bin it
stops the paddle from rotating and triggers the level output. The PLS is great for this
application as it not affected by pressure changes in the bin.
Lift stations are used to transmit wastewater to the treatment facility. Wastewater is
transmitted by gravity feed so it has to be continually elevated to provide height to
generate the flow. Lift stations are pits located at points in the wastewater system to
collect the wastewater that usually have two submersible pumps. Wastewater in the
lift station is pumped out to a higher level from where it can flow on to the next lift
station or to the treatment facility. The Mercoid® Series MPC pump controller is used
with the Series PBLT level transmitter to control the level in the lift station. The PBLT
is a level transmitter that is submersed in the tank and sends a linear output of the
height of wastewater above it. The MPC takes the height input and controls the pumps
according to how it has been programmed.
Grain hopper level controlled by Series PLS Paddle Level Switch.
Custom level sensing devices are built to meet each customer’s
specific requirements, providing visual indication, continuous
measurement, and point level control.
Typical Applications
The supply of grain pneumatically conveyed to this dispensing hopper is controlled
by two Proximity™ Series PLS paddle level switches. When the grain level falls to the
low limit switch, the supply is turned on until the hopper fills to the level of the high
limit switch which turns off the supply. Since grain dust is explosive, the explosionproof Series PLS provides the required safety protection. The PLS is a paddle level
switch and is not affected by the varying pressure in the hopper due to the cycling of
the pneumatic conveying system.

To meet various tank level measuring needs, Dwyer Instruments, Inc. offers customconfigured products built to customer specifications that provide visual indication,
continuous level measurement, and multiple point level measurement. Series VR or
MVR View-Rite Level Indicators are a safe way to keep the process isolated while
providing true visible indication. Unlike sight glasses, which can crack or break, ViewRite Indicators contain liquids entirely within their stainless steel enclosure. For
continuous level measurement needs, the Series CLT uses reed switch technology
to offer a more economical solution than expensive ultrasonic, submersible or RT
transmitters. Lastly, the Series F7-MQ can be used in virtually any tank to indicate
high and low alarms or to control pumps and valves.

Industrial sumps and other underground tanks are ideal applications for top-mounted
Mercoid® displacer type level controls. Easily installed, these controls use porcelain
displacers that do not float on the surface of liquids, but are suspended on a coil
spring and cable. As the liquid in the tank reaches the level of the upper displacers,
their weight decreases by an amount equal to the liquid displaced, allowing the spring
to move the cable upward, actuating the switch and the pump is turned on. As the
liquid level falls below the upper displacers they move only a small amount, staying
within the switch deadband until the liquid level falls to the center of the bottom
displacer. At this point the switch is deactivated stopping the pump. The pump will
remain deactivated until the water level rises to the upper displacers, repeating the
cycle. The displacers are not affected by turbulence, pressure or chemicals and are
excellent for tanks with viscous or dirty liquids. The level differential is easily adjusted
by repositioning of the displacers on the 316SS cable.
Standard float switches require at least an inch of liquid to attain enough buoyancy
to switch. This can be a problem in applications where low level sensing is required.
The hat-shaped design of W.E. Anderson’s F7-LL provides necessary buoyancy for
switching in only 5/8˝ of water. This is essential for air conditioner drip pans, low level
sumps, and drains. The F7-LL is also ideal for low alarms, where running the process
dry can result in catastrophic failure.
Mercoid® Model 123 level controls provide high and low alarm on
large de-aerator tank.
W.E. Anderson® Series OLS indicates level in heavy equipment
radiator.
Liquid level in the external piping equals level in the tank. When level rises to high
limit, float in upper Model 123 is lifted, actuating switch to sound high level alarm.
When level drops to low limit, lower Model 123 sounds low level alarm.
Many types of heavy industrial equipment use a liquid cooling system for the motor.
A vibratory trench roller is a machine that compacts sub-bases for roads, parking lots,
etc., and is an example of the type of equipment that would utilize this system. This
machine incorporates a radiator cooling system. In the system, cooling liquid
circulates through the engine preventing it from over heating. As the engine is cooled
the cooling fluid heats up. The fluid returns to the radiator to cool down before being
circulated through again. If there is not enough cooling fluid in the system the engine
will not be cooled enough and damage will occur. A W. E. Anderson® Series OLS
optical level switch is installed as a low level alarm. The level alarm is signaled by the
OLS before the cooling fluid gets to a critical low level, warning the operator of the
problem. The OLS uses an optical detection system superior for this application as
float controls may trip from machine vibration. Also the compact insertion length is
ideal for a small radiator.

PRINCIPLE OF OPERATION
The float located on the DTM is equipped with a magnet that moves with the liquid
level, vertically, along the stem, inside the storage vessel. Level reading is acquired
by simply removing the protective cap located on the top of the unit and lifting the
calibrated measuring tape until the magnetic interlock with the float causes a slight
pull. The indicator tape remains at this point while the level is read where the
calibration aligns with the top of the mounting. The indicator tape can then be
lowered back inside the unit stem for storage and protection.

by simply removing the protective cap located on the top of the unit and lifting the
calibrated measuring tape until the magnetic interlock with the float causes a slight
pull. The indicator tape remains at this point while the level is read where the
calibration aligns with the top of the mounting. The indicator tape can then be
lowered back inside the unit stem for storage and protection.

The Series WD3 Water Leak Detector protects equipment from water damage by
detecting the presence of water in drip pans in air handler units, under raised floors in
data centers, or on floors around sump pumps and drains. Water is detected once it
reaches a level that bridges the two conductive strips on the bottom of the housing.
Depending on the model ordered, audible and visual alerts provide local indication of the
alarm condition and an internal switch will give remote indication or control to prevent
further build up of water.
For applications where power is not available, the Model WD3-BP-D1-A is battery powered.
Otherwise, either AC or DC supply voltages can be used to power the water detector. The
sensing height can be adjusted to as low as 1/32˝ using the included adjustable mounting
bracket. The mounting bracket can attach to any flat surface by either using the attached
adhesive strips or mounting screws.

The small and discreet Model WD Water Detector is designed for dependable
detection of low levels of conductive liquids. The module features a sturdy and reliable
aluminum enclosure and is powered by 24 VAC or 24 to 30 VDC. Water sensing tape
attaches to module and if any liquid comes in contact with the tape the resistance is
changed and the alarm will be triggered. The tape is hydrophobic so it does not absorb any
of the liquid it is detecting which makes for a faster drying time and faster return to service
after a water leak.
The sensing tape is 1˝ wide and can be bought in lengths of 5´, 10´, 15´ and 25´. Multiple
tapes can be connected together to extend the coverage area which makes it ideal for
domestic as well as commercial applications. Features include power and alarm LED’s,
alarm test switch, continuous tape integrity self check and extendable tape sensor.

Rugged and reliable the Series L4 Flotect® Level switch operates automatically to
indicate tank level. Perfect for starting or stopping pumps, opening or closing valves, or
actuate level alarm signals. A unique magnetically actuated switching design gives
superior performance. There are no bellows, springs, or seals to fail. Instead, the freeswinging float attracts a magnet within the solid metal switch body, actuating a snap
switch by means of a simple lever arm. Float arm hinge design limits the arm angle to
prevent vertical hangup.
FEATURES
• Leak proof body machined from bar stock
• Choice of floats dependent on maximum pressure and specific gravity
• Weatherproof, designed to meet NEMA 4 (IP56)
• Explosion-proof (listings included in specifications)
• Installs directly and easily into tank with a thredolet or flange (see application
drawings)
• Electrical assembly can be easily replaced without removing the unit from the
installation so that the process does not have to be shut down
• Horizontal installation or optional top mount vertical installation
APPLICATIONS
• Direct pump control for maintaining level
• Automatic tank dump operations
• Control levels or provide alarms in sumps, scrubber systems, hydro-pneumatic
tanks, low pressure boilers, and various waste water/sewage treatment processes

LEVEL
Surprisingly compact, the Series L6 Flotect® Level switch is designed and built for years of
trouble-free service in a wide variety of process liquid level applications. Operation is simple and
dependable with no mechanical linkage as the level switch is magnetically actuated. The float lever
pivoted within the body moves when the process liquid displaces the float. A magnet on the
opposite end of the float lever controls a second magnet on the switch actuating lever located in the
switch housing.
FEATURES
• Leak proof lower body machined from bar stock
• Choice of models for direct side wall mounting or mounted in a tee to act as an external
float chamber
• Weatherproof
• Explosion-proof (listings included in specifications)
• Electrical assembly can be easily replaced without removing the unit from the installation
so that the process does not have to be shut down
• Sensitive to level changes of less than 1/2˝ (12 mm)

The Mini-Size Series L10 Flotect® Level Switches combine low cost with top quality
materials and construction for great value and years of reliable liquid level control. Wide
media compatibility is assured with a choice of brass or SS bodies and external tees;
polypropylene or SS floats. Two basic configurations are offered; with 1" male NPT
threads for direct side mounting through a half coupling or with factory installed tee for
external mounting.
All Series L10 switches feature a hermetically sealed, magnetically actuated SPST reed
switch which is encapsulated in a polypropylene housing. Units are quickly and easily
adjusted for your choice of normally open or normally closed operation thanks to a unique
design. Just loosen two screws and instantly slide the switch assembly to the action
required. NO and NC markings are clearly visible. This feature also speeds switch
replacement if damage occurs.
Three types of floats are offered to accommodate liquids with specific gravities as low as
0.5; max pressures to 2000 psig (137.8 bar). These controls are UL recognized and CSA
listed.

Series F6 & F7 compact level switches combine low cost and reliability with fast,
simple installation. Hermetically sealed reed switches are actuated by magnets
permanently bonded inside the float and can be easily adapted to open or close a circuit on
rising or falling levels. Vertical mount models are shipped with normally open switch
contacts which close as the float rises toward the mounting threads. Reverse switch action
by removing the float, rotating it end-for-end and replacing it on the stem. Vertical models
mount internally, oriented within 30° of vertical, or select optional fittings for external
mounting. Switch ratings are suitable for many solid state control systems and monitors
or alarms. Simple relay interfaces can be used for higher current applications.

Principles of Operation
The optical level switch employs an LED, which transmits infrared light. This light is sent
through a prism and reflected back to a photo-transistor utilizing two 90° light reflections.
With the prism surrounded by a gas, the light source is cast back to the photo transistor.
When a translucent liquid is introduced to the prism at or above the point where the light
source makes contract with the prism, the light is reflected into the liquid, not allowing
the photo-transistor to energize.

Series CLP Conductivity Level Probes are used to determine the presence of a
conductive liquid at a set level by sensing conductivity. The Series CLP is coupled with the
Series TSWB Temperature Level Controller for a complete level control system. These
probes allow for the measurement of conductivity between the probe fitting and end, which
is isolated by a ceramic insulator, or between the probe ends of two probes. The CLP can
be mounted in any orientation in a tank, tee fitting, or any compatible threaded port. The
probe end is solid stainless steel allowing substantial resistance to heat and corrosion.

The CLS2 is a capacitive technology level switch that does not have any moving parts
- no jams, no wear, nothing to break, and no maintenance. State of the art sensing
technology in the CLS2, using impulse RF admittance measurement combined with an
active guard, provides excellent level measurement and stability while being insensitive to
material buildup. This technology also provides immunity to external RF sources like
walkie-talkies and cell phones as well as minimal interference with radio communication
or other electronic systems.
Capacitive level technology can be used for liquids, powders, and bulk materials and is great
for difficult applications such as slurries, coating products, and liquids with solids. The
CLS2 is ideal for level indication in silos, receivers, and transporters in pneumatic conveying
systems. The CLS2 can also be used for liquid interface applications to detect the level of
two immiscible liquids that have different dielectric constants such as oil and water. Wetted
materials of PVDF and 316 SS assure great chemical compatibility and meet food grade
requirements.
FEATURES
• Automatic Calibration: No need to turn calibration pots, just push the
calibration button. The CLS2 even has an external magnet to activate the
calibration without having to open the enclosure.
• Universal Power Supply: One model works from 12 to 240 VAC/DC without
any jumpers or settings.
• Coat Guard: Unit is not affected by sticky, dusty, or clingy materials that coat or
build up on the probe, preventing false alarms.
• Failsafe Setting: Output switches can be set for NO or NC condition on loss of
power.
• Status Indication: Ultra high brightness external red LED switch status
indicator, and internal indicators for power, sensor, and switch status that can be
seen externally with window cap option (external LED on weatherproof model
only).
• Time Delay: Prevent false alarms from material splashing, agitation, etc.
• Removable Terminals: Removable terminal block snaps in and out enabling
easy wiring outside of the enclosure.

LEVEL
Model CLS1 Capacitance Level Switch provides reliable point level measurement of
solids, liquids and slurries in metallic or non-metallic tanks and vessels. Model CLS1
detects the presence or absence of material in contact with the probe by sensing a change
in the capacitance. Electronics provide highly sensitive measurement detection (requires
less than a 1 picofarad shift from ambient). State of the art technology ignores material
build-up on the vessel sidewall or along the probe assembly. One time calibration is simple
with a single multi-turn potentiometer. Red LED on housing indicates sensor status. Unit
features an adjustable 1-30 second time delay and a 5 amp, SPDT fail-safe relay output.
Model CLS1 can be mounted vertically or horizontally.

of material when other sensors won’t work due to bin vibration, or actual walls aren’t
available for mounting other types of measuring units. The probes are designed for use
where the bulk material to be sensed is exposed or open. Typical applications include high
or low level detection in large hoppers, silos, crushers, or trippers, high level control under
stackers, and detection of plugged conditions at conveyor transfer points. Series LTS
probes can also be used to detect the presence or absence of bulk material on belt
conveyors, on chutes to indicate product flow, and to aid in loading rail cars or trucks.
All probe models are airtight, dust tight, and waterproof. The compact probe should be
used for applications involving small bins and hoppers where space is limited, while the
heavy duty probe should be used for applications where a heavy duty abrasion-resistant
probe is necessary.

The Series LTC Tilt Probe Control Units feature an adjustable time delay and a logic
selector switch. The logic selector switch determines when the output relay actuates and
de-actuates, thus while in position one, the relay is energized when the probe is in the
vertical position and de-energizes when the probe is in the titled position, and while in
position two, the actions are opposite. In addition, an adjustable time-delay feature may be
assigned to either the vertical or the tilt position to prevent false signals. The relay assumes
the de-energized position upon reaching the end of the delay period as well as upon failure
of power to the controller.

COVER REMOVAL
Series TFLS tuning fork level switch is ideal for level control of powders and fine
grained solids, especially those with a low bulk density. The TFLS incorporates a
piezoelectric crystal that vibrates the fork at its natural frequency. When the fork comes
in contact with material the vibration is dampened and the switch changes state. As the
fork becomes free of material the switch changes back to its normal state. Featured in the
TFLS is user-selectable fail-safe operation of the contacts. Unit is not affected by vibration
from conveying systems, motors, or the movement of material. It can be mounted in any
position and is available with factory built extensions for mounting on the top of the storage
vessel.
Series TFLS is easy to use with no calibration required and with no mechanical moving
parts there is no routine maintenance required. The TFLS is unaffected by the dielectric
constant of the sensed material making it superior to a capacitance level switch for
applications where the dielectric constant is too low, where there is more than one material
being used in one vessel, and when material moisture content can change. The level switch
is also good for applications when the bulk density is too low for a rotating paddle level
switch. It can also detect granular material submerged in liquids of low viscosity, for
example sand, gravel, or polyester chips in water.
FEATURES
• No calibration required
• Vibrating fork design: Great for low bulk density and low dielectric constant
products. Will detect products down to 1.8 lb/ft3 (30 g/l)
• Universal power supply: One model works with 90 to 265 VAC and 24 VDC
• Adjustable sensitivity: Can be set to ignore lighter bulk density products and only
detect heavier products, such as sand in water
• Status indication: External LED switch indicator, and internal indicators for
normal and alarm status
• Failsafe setting: Output switch can be set for NO or NC condition on loss of
power
• Time delay: Prevent false alarms from material surges

The Model VRLS Vibrating Rod Level Switch is an economical choice in level
detection of powders and bulk solids. The VRLS utilizes a piezoelectric crystal that
vibrates the rod at a natural frequency. Once the rod comes in contact with the material,
the vibration will be dampened and the switch will change state. Once the rod is uncovered
by the material, the switch will revert to its normal state. Perfect for silo or hopper
applications, its probe design allows for self-cleaning, ensuring no build-up or bridging of
material and accurate detection. Sensitivity is adjustable for detection ranging from large
granular material to small powders with low bulk densities. The failsafe mode can be set
for failure on high level or failure on low level using a selector switch in the enclosure.

The Series PLS2 is an electromechanical level switch designed for level monitoring of
bulk materials. The rotating measuring vane is driven by a brushless synchronous motor
at one revolution per minute. As product builds up, the paddle rotation is impeded and the
resulting motor torque activates the output switch and stops the motor. A spring
mechanism reactivates the motor and returns the switch to normal state when the material
no longer impedes the paddle rotation. A torque adjusting mechanism eliminates the need
for different sized paddles. The PLS2 is designed with the industry standard 1-1/4˝ male
NPT connection and unit can be side or top mounted.
FEATURES
• 3 sensitivity settings
• Top or side mountable
• Brushless synchronous motor: Assures long term reliability and efficiency
• Motor shuts off when paddle stalls
• Screw cover: For easy access with no worries about losing bolts or screws

CLEARANCE FOR
COVER REMOVAL
Incorporated in the design of the PLS is a magnetic drive that is time proven by
decades of use in our Mark Series valve position indicator product line. A 1 rpm
synchronous motor rotates the paddle utilizing a magnetic drive. As product builds up the
paddle is impeded from moving and the resulting motor torque activates the output
switches and stops the motor. A spring mechanism reactivates the motor and returns the
switches to normal state when the product no longer impedes the paddle rotation.
Standard construction is weatherproof with explosion-proof optional, and the unit can be
side or top mounted. The PLS is designed with the industry standard 1-1/4˝ male NPT
connection and mounting flanges.
FEATURES
• Magnetic drive that isolates and completely seals the control head from the process
and environment preventing material or dust from entering the control head
• Motor shuts-off when paddle stalls increasing motor life, preventing motor burnout,
and decreasing power usage
• Slip clutch design enabled by the magnetic drive that prevents damage to motor
and drive mechanism from sudden or excessive loading on the paddle.
• Status indication light on weatherproof models
• Screw cover on the enclosure for easy access with no worries about losing bolts
or screws
• Modular design to allow field installation of any paddle, flanges, shaft extensions,
or shaft guards

A unique Magnetic Linkage isolates the electrical compartment from controlled product,
reducing maintenance and improving sensitivity. The sealed switch compartment and
sealed leads yield the utmost in reliable operation. A wide selection of diaphragms and
switches are available with choices of flange or suspension mounting to fit your specific
application. The dry level Ultra-Mag™ Level Switch is extremely sensitive and very economical.
The magnetic linkage makes this simple explosion-proof diaphragm switch the most rugged
and reliable level control for a variety of products (see cut-away above).
Mounting Selection: A choice of either suspension or flange mounting is available to
match your application. Flange mounting is the best choice for control of low or
intermediate level in vessels containing granular product that does not “bridge”, “rathole”,
or otherwise build up on vessel walls. Choose suspension mounting for high level in vessels
and for better operation with “bridging” product.
Diaphragm Selection: A wide variety of diaphragms are available to match product bulk
density, flowability, abrasiveness and temperature requirements while providing maximum
sensitivity. The best choice for vessels subject to pressure or vacuum is “breathable” fabric
(P Series), requiring no venting. Non-porous elastomer (G Series) type diaphragms are
the best choice for more abrasive product and broader temperature range applications.
Venting is always required with the G series and if used in pressurized vessels, venting to
the tank atmosphere is required to allow pressure equalization. A slide rule “Diaphragm
Selector” is available from the factory to help you choose the diaphragm best suited to your
application.

Suspension Assembly Kits: Pre-assembled kits are available
from the factory, or you can build your own kits using standard pipe
fittings shown in our Proximity Bill of Materials (Form No. 101).
Pipes and fittings are normally galvanized steel, but aluminum and
SS pipes and fittings are available. Units are secured to a steel cover
plate that rests on a rectangular steel flange welded into the top of
the vessel. Aluminum and stainless coverplates and flanges are also
available. Standard 48˝ L x 1˝ pipe provides working depth (WD) up
to 48˝. Longer pipe (to provide greater WD) is available. GS Series
switches have upper (L1 = 28˝ standard) and lower (L2 = 20˝
standard) 1˝ pipes, with a tee (for stilling pot) in between. A stilling
pot is required to equalize pressure and keep dirt from building up
behind the diaphragm. PS series require a 1/2˝ conduit in 1˝
suspension pipe for explosion-proof applications. The 1/2˝ conduit
(56˝ standard length) is a standard part of the GS series assembly.

LEVEL
Suspension Mounting is normally
used for high level monitoring in vessels.
For product over 20 lb/ft3, the level switch
(diaphragm face) should be located about
1/3 of the distance from the vessel wall to
1/3
the point of entry of the product. For
1/2
3
product less than 20 lb/ft , the unit should
be located closer to the point of entry of
the product, about 1/2 the distance from
the vessel wall to the point of entry.
Pressure required to depress the diaphragm and trip the switch is
in the range of 5 to 15 oz in the horizontal direction (perpendicular
to the diaphragm). Suspension mounting provides the easiest
vertical adjustment capability, greatest sensitivity and best
maintenance conditions.

SBLT2 and SBLTX Submersible Level Transmitters are manufactured for years of
trouble free service in the harshest applications. Both measure the height of liquid above
the position in the tank referenced to atmospheric pressure. The transmitters consist of
a piezoresistive sensing element, encased in a 316 SS housing. Bullet nose design protects
the diaphragm from damage.
The SBLT2 incorporates lightning and surge protection utilizing dual arrestor technology,
grounded to case, eliminating both power supply surges and lightning ground strike
transients (surge protection is not guaranteed and is not covered by warranty). The SBLTX
is UL approved intrinsically safe for use in hazardous locations when used with proper
barrier.
Units come equipped with a 270-pound tensile strength shielded and vented cable.
Ventilation tube in the cable automatically compensates for changes in atmospheric
pressure above the tank. The vent is protected with a maintenance free filter eliminating
particulate or water droplets from entering the transducers.

BREATHER TUBE
PBLT2 and PBLTX Submersible Level Transmitters are manufactured for years of
trouble free service in the harshest applications. Both measure the height of liquid above
the position in the tank referenced to atmospheric pressure. The transmitters consist of a
piezoresistive sensing element, encased in a 316 SS housing. Perfect for wastewater and
slurry applications with features to protect the unit from these demanding applications.
Large diameter 316 SS diaphragm seal is non-clogging and damage resistant to floating
solids.
The PBLT2 incorporates lightning and surge protection utilizing dual arrestor technology,
grounded to case, eliminating both power supply surges and lightning ground strike
transients (surge protection is not guaranteed and is not covered by warranty). The PBLTX
is UL approved intrinsically safe for use in hazardous locations when used with proper
barrier.
Units come equipped with a 270-pound tensile strength shielded and vented cable.
Ventilation tube in the cable automatically compensates for changes in atmospheric
pressure above the tank. The vent is protected with a maintenance free filter eliminating
particulate or water droplets from entering the transducers.

The Series FBLT Submersible Level Transmitter is designed with a flush
diaphragm tip that will not clog in harsh applications such as sewage lift stations.
Narrow body design allows the FBLT to fit into stilling wells and narrow installations.
The FBLT features a robust FKM fluoroelastomer diaphragm that is PTFE coated
for a stick resistant surface that will hold up in aggressive fluids. The diaphragm
cavity is filled with a gel that will not leak out versus oil or grease that our competitors
use. Body is constructed of 316 SS and the cable is either polyurethane or ETFE
for more corrosive applications.
The unit measures the height of liquid above the position that it is mounted in a tank
or pit in reference to atmospheric pressure. Ventilation tube in the cable automatically
compensates for changes in atmospheric pressure above the fluid. The vent is
protected with a maintenance free filter, eliminating particulate or water droplets from
entering the transmitter. For extra protection against humidity, we offer the A-297
desiccant filter that can be attached to the vent tube.
The FBLT incorporates lighting and surge protection (not guaranteed or covered by
warrantee) to stand up in harsh applications. Optional NPT connection allows the
unit to be rigidly installed in a pipe/conduit, or to attach our A-625 hanging loop for
attaching a chain for pulling out of the installation.
APPLICATIONS
Sewage lift stations, industrial slurries, industrial sumps, landfill leachate, reservoirs,

The Series CRF2 is a level transmitter providing a two-wire 4 to 20 mA output to indicate
level of liquids, powders and bulk materials. State of the art sensing technology in the
CRF2, using impulse RF admittance measurement provides excellent accuracy and
stability. The CRF2 senses capacitance changes resulting from the height of the material
in the tank between the probe and the tank wall. In non-metallic tanks or tanks that do not
have the wall parallel to the probe a ground reference must be used.
The CRF2 comes with either a rigid or flexible probe depending on application installation
need and probe length required. Featured in the CRF2 is easy push button calibration of
zero and span. Custom order the CRF2 to any length probe that you need for your
application. FEP covered probe is ideal for use with corrosive media. This technology also
provides immunity to external RF sources like walkie-talkies and cell phones as well as
minimal interference with radio communication or other electronic systems.
The CRF2 is perfect for level indication in bins, hoppers, or small silos of powder and bulk
materials.

The Series DBOB is a low maintenance, electromechanical device designed for the
continuous measurement of level or volumes in silos, tanks, or hoppers. The DBOB utilizes
an internal motor that drives a weight suspended by a firm stainless steel tape down to
the bulk material level. Upon reaching the material, the unit reverses and the weight is
drawn back into the upper stop position. The distance the weight descends is electronically
measured based on the internal rotations of the unwinding tape. The DBOB is userprogrammable to output either a height signal or a volumetric signal based on the vessel
geometry. The unit’s two programmable relays offer even more customization.
The 1-1/2˝ NPT process connection allows for simple installation on horizontal surfaces
and an optional aiming flange is available for inclines. The integrated tape cleaner keeps
the internal process protected from difficult material and the tough cast housing protects
the unit from its surroundings. With an easy to understand measurement principle and
inherent low maintenance qualities, the Series DBOB is perfect for your level measuring
needs.
FEATURES
• Measurement range up to 100 ft (30 m)
• Optional aiming flange for versatile mounting
• Accurate measurement
• Independent of bulk material properties
• Tangle free tape-based system

LEVEL
The Mercoid® MPC Pump Controller provides versatile level control in a standard 1/4
DIN package. Designed for use with almost any style level transmitter the unit displays
the present level and main set point value. Incorporated in the MPC is programmable level
differential for on/off control of one or two pumps, valves, or other devices through two
SPDT relays. Also featured are two additional programmable alarm contacts with front
alarm light indication.
The MPC is flexible and incorporates a user-friendly programming menu. The front face
meets NEMA 4X (IP66) for outdoor panel mounting. So many features are combined into
the MPC that it eliminates many components in a pump control system.
FEATURES
• Selectable pump alternation when used with two pumps to minimize pump wear.
With alternation “on” a seal failure or over temperature condition will force the
non-failed pump to lead status and stop alternation.
• When used with a submersible pump including a moisture sensor th MPC has
alarm light indication of seal failure.
• When used with a pump including a thermostat the MPC has alarm light
indication of pump over temperature and removes the pump from service. The
pump can be brought back into service automatically or by manual reset when
the pump has cooled down.
• Alarms can be programmed for output indication of pump seal failure or over
temperature.
• Selectable time delay, for pump two, on power up to prevent both pumps from
starting at the same time. If power is lost, upon regaining power a time delay of
up to 60 seconds can be selected to prevent too large of a current draw.
• Integral 24 VDC power supply for level transmitter.
• Displays pump run time from a front panel button.
• Test system function that simulates the process input to ensure the pumps are
operating or to test programming.
• User selectable security lock-out of programming and/or set points.
• Process input retransmission as a current (4 to 20 mA) or voltage (2 to 10 VDC)
analog signal*.
*Standard model MPC is set for current retransmission. For voltage retransmission
add suffix “-RV”.

Series DLD Dual Channel Leak Detection Relay is used to monitor the shaft seals
of two submersible pumps to detect a leak before pump failure. A leak is detected by
sensing the status of a float or conductivity switch installed in the seal cavity. When this
resistance drops below the set sensitivity, the output relay energizes and the corresponding
LED indicator illuminates. The DLD offers normally open relay contacts to energize an
alarm or de-energize the pump in the event of a leak. When the seal failure condition clears,
the relay automatically resets.

Series BAP Bin Aerator Pad provides positive flow of dry, finely ground materials from
any bin using the proven principle of aeration. Low pressure air is introduced into the
product, restoring its natural ability to flow. In this way congestion, bridging and rat-holing
are overcome without resorting to brute force. Series BAP is non-clogging and provides
equal distribution and consumption of air. The aerator pads feature simple and quick
installation, are inexpensive, and adapt to any bin configuration. Aeration gives the best
results on materials with a 60 mesh size or smaller and with a 3% or less moisture content.

and against electroplating build-up. It can also be used on material compacted while packing
or sand compacted while molding. The aluminum body is equipped with a steel ring and
ball inside that is tightly closed by plastic side covers. Vibration is caused when the internal
ball, pushed by compressed air, runs in a rotary motion to produce centrifugal force.

Series PRV Pneumatic Roller Vibrators have a high vibration frequency feature that
can prevent material jams in pipe delivery. It can also be applied for bridge-break or
concrete injection operation conditions. The special aluminum body is equipped with a
roller and ring with multi-nozzles. It is tightly closed by plastic side covers. Vibration is
caused when the roller pushed by compressed air runs in a rotary motion to produce
centrifugal force.

Series PTV Pneumatic Turbine Vibrators are the best choice of high vibration
frequency types for a low noise environment. It is usually installed on a vibrating separator,
conveyor, automatic arrangement machine, packing machine, or filling machine. The
vibration is produced by centrifugal force which arises from the imbalance of movement
when compressed air impacts the tangent of the turbine to make it move. The operation
noise is low because of ball bearing supports on the running turbine.

Housing Material: Aluminum.
How They Operate
There are air-breathing tubes located in both ends of the cylinder. Compressed air
pushes the piston from one side to the other. Vibration power arises when the piston
moves back and forth in the body. In APV-C air cushion at both ends produced by
the to-and-fro motion will keep the piston from striking the body. Therefore, the piston
will not produce much noise. In APV-I, air cushion at the top end is produced by the
to-and-fro compression. This will keep the piston from striking onto the body top.
The piston will strike directly on the bottom side of the body to produce a strong
impact.

How It Operates
The IPV series air hammer contains a powerful magnet inside the hammer. The
hammer and magnet are tightly closed before activation. As the inlet air pressure
gets higher than the force, this tightens the hammer and magnet. The hammer and
magnet will separate and cause more strength for impact power. The spring will bring
the hammer back to the initial position automatically after the impact. By doing this,
the air pressure will be released and the strength of the air pressure will be delivered
to the target impact container. It will help to smooth the flow and prevent accumulation
inside the container.

Bin Vibrators/
Aerators
The Series EBV Electric Bin Vibrator incorporates adjustable force features without
creating irritating noise. The low amperage draw at 120V reduces power consumption and
makes the vibrators useable in any application. The EBV eliminates drawbacks associated
with non-adjustable constant force units. The conventional fix force units are sized with
narrow operating limits and may not move material from bins or pack material in
containers if the moisture content changes. The adjustable force feature increases
application flexibility; reducing equipment downtime and labor expense. The EBV is
capable of running continuously at 100% force output without overheating or mechanical
damage.
