Designers of a bio-medical incubator rely on a
Dwyer® flowmeter to control CO2 flow.
Flowmeters and/or differential pressure switches
monitor vital purge gas flow to motors, switchgear,
instruments.
This low temperature incubator with CO2 atmosphere is used in
bio-medical applications, such as short term blood work and long
term tissue culture studies. CO2 is introduced at a high initial
purge rate controlled by a timer. After the purge period, a Dwyer®
Visi-Float® flowmeter with a metering valve is utilized to adjust and
monitor the CO2 flow in cubic centimeters per minute. The VisiFloat® flowmeter provides the reliability and accuracy needed to
complement the host of high performance features designed into
this incubator.
To purge motors, generators, switchgear, and industrial instrument
cases, Dwyer® flowmeters are installed in the supply line to
indicate a flow of air, manufactured inert gas, or nitrogen to these
devices. The flowmeters (with valves) allow maintenance
personnel to set the flow quickly and recheck anytime to make
sure proper flow continues. A Dwyer® differential pressure switch
can also be used to monitor proper flow on a continuous basis
and provide a signal or alarm if purge gas flow fails. Such an
optional switch is shown above, monitoring proper flow of purge
gas to the switchbox as a function of pressure drop across the
flowmeter. The purging of electrical equipment in hazardous areas
may require more extensive control and monitoring devices.

Metering valves on Dwyer® flowmeters control air/gas
intake on permanent air pollution analyzers.
Operator uses Mini-Master® flowmeter to verify air
flow into portable dust monitor.
Regulations regarding air pollution levels require continuous
monitoring a source and ambient pollutants in areas where
noxious gases are generated. Ambient air quality samplers utilize
either Visi-Float® or Rate-Master® flowmeters to establish the
proper flow of sample or carrier gases into the analyzer. Top
mounted metering valves are recommended for flowmeters used
in vacuum service to maintain specified accuracy.
The small size, accuracy, and low cost of the Dwyer® Mini-Master®
Series flowmeter lends itself perfectly to use in this portable,
battery-operated dust monitor. Using a light scattering electronic
sampler, a small vacuum pump draws air through the flowmeter
into the sampling chamber, and the flowmeter verifies the proper
volume of sample air flow. Readout is digital and directly in dust
weight per cubic meter of air.

Brass body gage measures water flow rates.
Large air conditioning and refrigeration systems which include
water cooled condensers require that the water must circulate
through the condenser and cooling tower in sufficient volume
before the compressor is started. Here the W.E. Anderson®
Flotect® flow switch is connected to the compressor control circuit
to prevent starting or to shut down the compressor control circuit
if the flow of cooling water falls below that required for proper
operation. A dual Flotect® switch (available as an option) will also
trigger a remote alarm to signal the operator of the shutdown as
soon as it occurs.

When proper fluid circulation in a system is critical, the W.E.
Anderson® Flotect® flow switch will automatically start a standby
pump should the main pump fail. The flow in the main path of the
parallel system illustrated keeps the Flotect® flow switch in an
open position. When the main pump fails, the flow will cease. The
flow switch then closes, starting the standby pump.
In this gravity feed system delivering liquid fertilizer to portable
tanks, a Midwest Model 100 sight flow indicator was installed. The
operator can see the rotating vanes to check for adequate flow at
any time.

A Dwyer® brass body Capsuhelic® differential pressure gage,
required for water service to prevent corrosion damage to the
gage, is used in conjunction with a Dwyer® Series DS-300
averaging Pitot tube. The Capsuhelic® gage provides a basic
method of measuring water flow rates. As a guide in selecting the
appropriate Capsuhelic® gage range, the designer can consult
data provided with the DS-300 averaging Pitot tube. This relates
differential pressure in inches of water column to the water flow in
gallons per minute for the pipe size involved. The gage can be
calibrated directly in GPM if desired. Bleed fittings installed in the
top ports of the gage are recommended to facilitate removal of air
from the system.
Flotect® flow switch ensures cooling water
circulation before air conditioning compressor motor
starts.

Flows of air and gases used in a special furnace are
controlled by Dwyer® flowmeters.
Durable dual-column flowmeter adds value for
physicians and oral surgeons.
A total of eleven Dwyer® Rate-Master® flowmeters function in the
design of this sophisticated conveyor belt furnace used in
manufacturing electronic devices. The flowmeters provide precise
adjustment and monitoring of the flows of air and gases into the
various portions of the furnace, which allow it to perform different
operations, such as decarburizing and oxidizing, metallic package
sealing, glass package sealing, and glass-to-metal sealing.
Physicians and oral surgeons who use anesthesia or analgesia in
their offices on an occasional basis require a system that is
reliable but small and portable. One such system employs special
Dwyer® dual-column Visi-Float® flowmeters to meter and monitor
precise flows of nitrous oxide and oxygen to the patient. In
addition to meeting the performance level demanded by this
application, the Visi-Float® flowmeters are durable and attractive
complements to this important and visible medical device.

In this set-up, the Magnehelic® gage measures higher air
velocities as a function of the pressure drop across a sharp-edged
orifice plate in the pipe. The pressure drops can be converted to
air velocity using orifice plate data supplied by the manufacturer.
Details regarding available sizes, ranges, installation, and
limitations are available from orifice plate manufacturers and from
standard handbooks. A Dwyer® Durablock® inclined manometer
or Photohelic® differential pressure switch/gage can also be used.
In addition to the visual reading gage, the Photohelic® switch/gage
provides an alarm signal or shutdown control function. Pressure
sensing taps should be located on the side or top of the pipe or
duct to prevent condensation from draining into sensing lines or
gages.
Salt corrosion test cabinet includes a Dwyer®
flowmeter for adjustment of bubbler air flow.
Prior to atomizing a heated salt solution to produce a fog inside
this corrosion test cabinet, compressed air is bubbled through a
heated water column to properly heat and humidify the air. A
Dwyer® Visi-Float® VFA flowmeter, as part of the system, provides
precise adjustment of the bubbler air flow to meet test standards.

Note: The corrections shown in the curves and in the formulas are for variations in specific gravity
and internal pressure* only. Further correction may be necessary for variations in viscosity and
changes in type of flow from laminar to turbulent or vice versa. This is particularly true in the case
of extremely low flows of the lighter gases. Nevertheless these charts and correction factors can
be quite useful when dealing with small changes in pressure* and specific gravity.

Despite its compactness, the MMA flowmeter features a 2˝ scale which
combined with precision molding, enables highly repeatable readings to be
made to within ±4% accuracy.
Offering advanced features at low cost, the Series MM flowmeters are ideal
for a wide range of OEM and user applications in medical equipment, air
samplers, gas analyzers, pollution monitors, chemical injectors, cabinet
purging, etc.
Where a compact flowmeter is required to measure small volume air flows, the
Model MMF is recommended. Easy to mount, they require a minimum of panel
space. A white back on the flow tube makes the ball float easy to see. The 1-1/2˝
scale is highly visible and easy to read. Scale graduations are printed on
aluminum alongside the flow tube (not on it), so the position of ball float is
instantly visible.
The standard Model MMA flowmeter is suitable for both gas and liquid
applications. It can be configured by the user with the parts provided to have
non-removable top or bottom front mounted metering valves or no valve at all.
The transparent nylon material provides high chemical resistance, low moisture
absorption and is transparent to facilitate routine inspection. Using the
assembly key provided, the flowmeter can be disassembled anytime for cleaning
or reconfiguration. In OEM quantities, ultrasonically welded caps or
interchangeable mold cores enable production of the MMA flowmeter with a low
profile or flat front surface where no valve is required.
The Model MMF’s bezel type mounting is modern, attractive and quickly
installed from the front of instrument panel. Two 1/4˝ O.D. mountingconnection tubes are integrally molded with flowmeter body. They can be back
connected to flexible rubber or plastic tubing and held in place with two spring
retainers which are furnished. If preferred, connections may be made to metal
or rigid plastic tubing with a double compression fitting or nylon tube union
such as Dwyer Part No. A-328.
The MMA is practically unbreakable, mounts easily, and is easy to read. Two
5/16˝ O.D. mounting — connection tubes permit quick push-on connection of
rubber or plastic tubing. A bottom clip for “stand up” mounting is also provided.
Excellent repeatability and ±10% accuracy make the MMF flowmeter an
excellent value at its low cost.

Easy-to-Interchange bodies — Within a given Series Rate-Master® flowmeter bodies
can be instantly interchanged. Simply “unplug” the body from backbone and replace it with
another. “O” rings provide a tight seal on inlet and outlet. Piping remains undisturbed.
Interchangeability is useful where different scale ranges are sometimes required at the
same location in the laboratory or plant.
Construction assures accuracy — All Rate-Master® flowmeter bodies are injection
molded of tough, clear, shatter-proof polycarbonate plastic around a precision tapered pin.
The result is accurate and repeatable readings. The single piece plastic body is mounted to
a stainless steel back bone into which pipe thread inserts are welded to absorb piping
torque. Precision metering valves of brass or stainless steel (specify BV or SSV on order)
are available as an optional extra and permit precise flow adjustments. For vacuum
applications, Model RMA units are available with top mounted valves (specify TMV). The
small Series RMA models are accurate within ±4% of full scale reading; Series RMB within
±3%; large Series RMC within ±2%.

Installation is simple — The Rate-Master® Flowmeter can be neatly panel mounted to
keep flow tube centers in the same plane as the panel surface or surface mounted on the
panel by means of tapped holes in the backbone. When through-panel mounted, the bezel
automatically positions the instrument at the correct depth in the panel cutout. Surface
mounted units can also be held in place by the piping. All mounting hardware plus
installation and operating instructions are included.
Easy to read design — The direct reading scales eliminate troublesome conversions. The
scales are brushed aluminum, coated with epoxy and the graduations are on both sides of
the indicating tube. Special integral flow guides stabilize the float throughout the range
to keep it from hunting or wandering in the bore. The float is highly visible against a white
background.

Durable and attractive construction — The machined acrylic bodies of the
Visi–Float® flowmeters are practically unbreakable. Fabrication is backed by
over 60 years of experience in acrylic instrument machining. The tapered bore
is precision machined to a smooth surface that provides perfect visibility of the
indicating float. The VFA and VFB models are available with either brass or
stainless steel inlet and outlet connections and are tapped for 1/8˝ NPT thread.
VFB models 85 and 86 have either 1/4˝ back or 3/8˝ end connections. All
standard models employ Buna–N “O” rings for leak proof operation and are
available with either back or end connections for horizontal or vertical piping.
Precision metering valves in brass or stainless steel are available for most VFA
and VFB models.
The Visi–Float® flowmeter bodies are cut and precision machined from
solid, clear acrylic plastic blocks. This construction not only produces a
handsome finished product, but permits complete visual inspection. As a result,
the Visi-Float® flowmeters are especially popular for medical and laboratory
equipment applications.
Scales are easy to read — The front scale location and white background
provides excellent visibility. The direct reading scales are hot stamped into the
plastic and will not wear off. Mid–range calibration is established with a master
flowmeter. Accuracy is ±5% of full scale for VFA models, ±3% for VFB. Scales
average 2" long on the VFA models, 4" long on VFB.
Easy installation — All Visi–Float® flowmeters have metal mounting inserts
on rear for panel mounting. They can also be supported directly by system
piping.

Accurately measure flow rates of air, water, and other commonly used gases
with the Series VA Variable Area Glass Flowmeters. Flowmeters are designed
with an easy-to-read universal mm scale and supplied with a correlation chart
containing calibration data for air and water. Correlation data for other gases
and liquids are available. Permanently fused ceramic scale with vertical locator
line reduces parallax and eye fatigue. Thick polycarbonate front shield protects
tube from breakage and also serves as a magnifying lens to enhance reading
resolution.
Glass flowmeters are suitable for metering carrier gases, liquid and gas
measurement in pilot plants, laboratories, process flow and level indicating. Units
are equipped with a standard 6-turn needle valve for flow rate control. High
precision metering valves with non-rising stems (sold separately) are available
for high sensitivity control and resolution – particularly suited for very low flow
rates.
Flowmeters are shipped completely assembled and ready for panel mounting.
Use an optional acrylic tripod base to convert to self-standing bench mounting.

Series RSF Flowmeters are designed with unique rotatable scales of dual, air-water direct
reading graduations. Flow rate is indicated in SCFM and SLPM for air and GPM and LPM
for water. Graduations are marked on a rotating, polycarbonate tubeshield which also serves
to protect the borosilicate glass flowtube. Flowmeters include a reflective plastic background
and 1.5 X magnification lens to reduce eye fatigue and allow for more accurate readings. A
blow-out back panel provides additional protection in the event of breakage. Series RSF
Flowmeters are available in vertical in-line mounting or panel mounting. Units are shipped
completely assembled and include standard mounting hardware for quick installation.

The Compact Series OMA Oxygen Flowmeter is made especially for medical
applications and manually controlling flow from oxygen generators. Flow levels are kept
stable by precision valve and knob adjustment. The low cost flowmeter is made from
durable clear acrylic plastic. The easy-to-read scale is hot stamped into the acrylic so it will
not wear off. The ball float is highly visible against the light blue background. Readings
are repeatable within ±4% full scale accuracy.

Low cost, Series HF In-Line Flow Monitors have a design based on a
floating sharp-edged orifice disk and variable area flow measurement to yield
accuracy of ±2.5% over center one-third of scale. This unique design allows
accurate performance with fluid viscosities up to 500 SSU. All internal wetted
parts are contained inside a sealed metal tubular casing assuring a virtually
maintenance-free unit. Flowing media forces linear motion of a spring loaded,
sharp edge orifice disk and ring shaped transfer magnet which both ride on a
tapered center shaft. The transfer magnet drives a clearly visible magnet
follower located outside the flow tube, protected under the clear polycarbonate
tube. A ring on the magnet follower indicates flow rate on the direct reading
scale. Rubber bumpers are provided for external impact resistance.
Designed for single-direction flow, Series HF Monitors are recommended for use
with system filtration of at least 74 microns or a 200 mesh screen. Some
applications may also require magnetic filtration. These flowmeters do not require
inlet or outlet straight plumbing and can be mounted horizontally, vertically, or
inverted.

speeds. Check pump high pressure performance, pressure relief valve
settings, fluid handling systems in agricultural, construction or industrial
machinery, power tools and equipment. Monitor petrochemical operations
with brass or stainless steel models. Industrial pneumatic systems air flow
can be monitored with the HFA models which are calibrated at 100 psig inlet
pressure.

The Series P72 Flowmeters are heavy bodied meters for corrosives, gases, and high
purity fluids. These meters are designed specifically for demanding applications. They are
economically priced meters ideal for caustic solutions as well as liquid chlorine, sodium
hypochlorite and chlorine gas. The Series P72 Flowmeters are suited for water treatment
facilities that deal with these aggressive types of gases and fluids. The P72-A is comprised
of P72 and polysulfone, while the P72-B has all P72 wetted components for maximum
corrosion resistance. Units have a full-scale accuracy of ±2% and can be disassembled
quickly without the meter being removed from the pipeline for easy cleaning. The Series
P72 Flowmeters are available with standard 3/4˝, 1-1/2˝, 3˝, and 4˝ flange connections.
Optional NPT connections are also available.

Sensing ports — Multiple upstream and

to provide effective accurate pressure
averaging, even at lower velocities.
In-Line Flow Sensors are averaging Pitot tubes that provide accurate and
convenient flow rate sensing for schedule 40 pipe. When purchased with a
Dwyer® Capsuhelic® differential pressure gage of appropriate range, the result
is a flow indicating system delivered off the shelf at an economical price.
Pitot tubes have been used in flow measurement for years. Conventional pitot
tubes sense velocity pressure at only one point in the flowing stream. Therefore,
a series of measurements must be taken across the stream to obtain a
meaningful average flow rate. The Dwyer® flow sensor eliminates the need for
“traversing” the flowing stream because of its multiple sensing points and builtin averaging capability.

The Series DS-300 flow sensors are designed to be inserted in the pipeline
through a compression fitting. They are furnished with instrument shut-off
valves on both pressure connections. Valves are fitted with 1/8˝ female NPT
connections. Accessories include adapters with 1/4˝ SAE 45° flared ends
compatible with hoses supplied with the Model A-471 Portable Capsuhelic® gage
kit. Standard valves are rated at 200 psig (13.7 bar) and 200°F (93.3°C). Where
valves are not required, they can be omitted at reduced cost. Series DS-300 flow
sensors are available for pipe sizes from 1˝ to 10˝.

DS-400 Averaging Flow Sensors are quality constructed from extra strong
3/4˝ dia. stainless steel to resist increased forces encountered at higher flow
rates with both air and water. This extra strength also allows them to be made
in longer insertion lengths up to 24 inches (61 cm). All models include
convenient and quick-acting quarter-turn ball valves to isolate the sensor for
zeroing. Process connections to the valve assembly are 1/8˝ female NPT. A pair
of 1/8˝ NPT X 1/4˝ SAE 45° flared adapters are included, compatible with
hoses used in the Model A-471 Portable Capsuhelic® Gage Kit. Supplied solid
brass mounting adapter has a 3/4˝ dia. compression fitting to lock in required
insertion length and a 3/4˝ male NPT thread for mounting in a Threaded
Branch Connection.

FLOW
Merely determine the pipe size into which the flow sensor will be mounted
and designate the size as a suffix to Model DS-300. For example, a flow
sensor to be mounted in a 2˝ pipe would be a Model No. DS-300-2˝.
For non-critical water and air flow monitoring applications, the chart below
can be utilized for ordering a stock Capsuhelic® differential pressure gage
for use with the DS-300 flow sensor. Simply locate the maximum flow rate
for the media being measured under the appropriate pipe size and read
the Capsuhelic® gage range in inches of water column to the left. The DS300 sensor is supplied with installation and operating instructions, Bulletin
F-50. It also includes complete flow conversion information for the three
media conditions shown in the chart below. This information enables the
user to create a complete differential pressure to flow rate conversion table
for the sensor and differential pressure gage employed. Both the Dwyer®
Capsuhelic® gage and flow sensor feature excellent repeatability so, once
the desired flow rate is determined, deviation from that flow in quantitative
measure can be easily determined. You may wish to order the adjustable
signal flag option for the Capsuhelic® gage to provide an easily identified
reference point for the proper flow.
Capsuhelic® gages with special ranges and/or direct reading scales in
appropriate flow units are available on special order for more critical
applications. Customer supplied data for the full scale flow (quantity and
units) is required along with the differential pressure reading at that full
flow figure. Prior to ordering a special Capsuhelic® differential pressure
gage for flow read-out, we recommend you request Bulletin F-50 to obtain
complete data on converting flow rates of various media to the sensor
differential pressure output. With this bulletin and after making a few
simple calculations, the exact range gage required can easily be
determined.

Model A-471 Portable Kit
The Dwyer® Series 4000 Capsuhelic® differential pressure gage is ideally
suited for use as a read-out device with the DS-300 Flow Sensors. The gage
may be used on system pressures of up to 500 psig even when the flow sensor
differential pressure to be read is less than 0.5˝ w.c. With accuracy of ±3% of
full scale, the Capsuhelic® gage can be used in ambient temperatures from 32
to 200°F (0 to 93.3°C). Zero and range adjustments are made from outside the
gage. The standard gage with a die cast aluminum housing can be used with
the flow sensor for air or oil applications. For water flow measurements, the
optional forged brass housing should be specified. The Capsuhelic® gage may
be panel or surface mounted and permanently plumbed to the flow sensor
if desired. The optional A-610 pipe mounting bracket allows the gage to be
easily attached to any 1-1/4˝- 2˝ horizontal or vertical pipe.

The Series PE Orifice Plate Flow Meter offers one-piece PVC construction incorporating
a unique holder or carrier ring containing metering taps and integral gaskets. Unlike a
standard orifice plate, the Series PE is a true primary element including the various
components for differential pressure measurement. It was designed for use wherever there
is an application for a conventional flow orifice plate. It can also be used in place of other
primary differential producers for efficiency and cost effectiveness. The Series PE is available
in line sizes from 1/2˝ to 24˝ and used for air and most gases. It meets or exceeds ASME,
AGA & ISO standards.
SERIES PE FEATURES
• Mounted with standard flanges
• Standard “corner tap” configuration
• Corrosion free material
• Simplified installation
• Built in metering taps (1/4˝ female NPT STD)
• Proven through a wide range of applications for accuracy and energy efficiency
• Assures long term reliability and accuracy
The Series TE Orifice Plate Flowmeter offers one-piece PTFE construction similar to
the OP and PE Series orifice plates, which incorporate a unique holder or carrier ring
containing metering taps and integral gaskets. Available for line sizes from 1/2˝ to 24˝, the
Series TE orifice plate can be used with gases, liquids, corrosive, and high temperature
fluids. The Series TE can be easily installed by slipping the unit between standard flanges
(orifice flanges are not required). The Series TE was designed for use anywhere there is
an application for a conventional flow orifice plate. It can also be used in place of other
primary differential producers for efficiency and cost effectiveness.
SERIES TE FEATURES
• Excellent chemical resistance
• Weather resistant
• Flame retardant (without factory gaskets)
• Low friction (minimum wear)
• Orifice plate thickness 1/4˝ offering greater stability

Rugged and reliable the Series V4 Flotect® flow switch operates automatically to
protect equipment and pipeline systems against damage from reduction or loss of flow.
The V4 is time tested being installed in thousands of pipelines and processing plants around
the world. A unique magnetically actuated switching design gives superior performance.
There are no bellows, springs, or seals to fail. Instead, a free-swinging vane attracts a
magnet within the solid metal switch body, actuating a snap switch by means of a simple
lever arm.

Surprisingly compact, the Series V6 Flotect® Flow Switch is engineered to
specifically monitor liquid, gas, or airflows. Operation is simple and dependable with no
mechanical linkage as the flow switch is magnetically actuated. The lower body holds the
flow vane and one magnet, which controls the switch actuating magnet in the separate
upper housing. In most applications the switch is normally off with the pipeline flow forcing
the vane against the vane spring. As the flow decreases the vane spring pushes back the
vane, actuating the switch to signal an alarm or shutdown. Tees are available for installation
in pipelines from 1/2˝ to 2˝, with bushings added the unit is easily adapted to 1/4˝ and 3/8˝
piping.

Designed to provide an inexpensive, reliable unit to monitor the presence or
absence of flow in a system. The V10 flow switch is used to monitor unattended equipment
and protect it from costly damage. The V10 flow switch utilizes a rugged, hermetically
sealed reed switch which is encapsulated in a polypropylene switch housing that fits into a
standard heavy duty leak proof brass body or optional 303 SS body. The switch adjustment
allows the user to change the switch to Normally Open (NO) or Normally Closed (NC) in the
field merely by loosening two screws. The switch housing is located outside the process
media, making switch change-over or maintenance easy without interruption of process
flow.
A full size, trimmable stainless steel vane is provided with a removable laminated template.
This template is calibrated for brass or ductile iron reducing tees and forged steel straight
tee/bushing combinations. Allows for field installation in pipelines from 1/2˝ to 2˝ diameter.
A table with approximate actuation and deactivation values is provided below.

V8 Flotect® Flow Switch Protects Equipment: Operation is simple and dependable.
In most applications, the switch is normally off while there is sufficient flow of liquid or air.
When flow stops, the vane spring moves the vane, actuating a single pole double throw
switch rated 5A @ 120/250 VAC to start or stop motor, pump, engine, etc. Operate a damper
or valve; shut down a burner or actuate an alarm or signal, protecting unattended
equipment from damage or loss of production.
The V8 Flotect® Flow Switch has a leak proof body and vane constructed of tough durable
polyphenylene sulfide which has excellent chemical resistance. The full size trimmable vane
is provided with molded-in graduations allowing for installation in a 1 inch through 6 inch
pipe. Operating pressures are up to 150 psig (10 bar) and temperatures to 212°F (100°C).
The V8 flow switch can be used in various chemical processes, industrial systems and
similar applications where process conditions are compatible with polyphenylene sulfide,
ceramic 8 and 316SS. The V8 Flotect® flow switch is UL recognized as an industrial motor
controller per UL standard 508, suitable for mounting in a protected environment.

Series FMS Flow Sensor FMS-1 is for applications requiring RELATIVE
measurement and set-point of flow rate. This means that the actual velocity of the flow or
the quantitative measurement in GPM is not known and is not important. What is
important is that the set-point can be set as a “percentage of” or “relative to” the full flow
rate. No other flow sensor could do it this simply or effectively.
How It Operates
The model FMS uses a set of flashing LED’s to indicate flow. All 7 of the LED’s will
remain lit to show 100% flow rate. The flow OK light will also be lit showing that the
established full flow rate is what is flowing in the pipe. When you initially set the flow
rate, it will mark that as your 100% mark. If your flow reduces below the 50% mark,
you will get an alarm from the sensor.
If flow increases beyond the initially established flow rate, the “Overflow” LED light
will come on.

FLOW
The transparent Series P5 Shuttle Flow Switch features corrosion resistant, durable
PVC housing for visual confirmation in flow/no flow applications. The switches have preset
actuation points from 0.5 to 2.0 GPM for actuation on increasing flow. Switching is SPST
normally open at no flow. Choose from 1/2˝ NPT or 3/4˝ IPS (for 0.5 GPM) or 1˝ IPS (for
2.0 GPM) inlet and outlet ports. The shuttle design has only one moving part for long life
and minimum maintenance. Remove the one-piece bonnet and shuttle assembly to quickly
clean the unit without disturbing the housing or piping. Rugged construction and excellent
chemical compatibility simplify flow / no flow detection.

The TDFS uses an impulse thermal dispersion measurement technique to
measure the flow rate where the probe is heated above the process temperature
and then is allowed to cool down to the process temperature. Empty pipe is not
a problem with the TDFS unlike some competitor units that will overheat.
Thermal flow switches can offer better long term reliability and life expectancy
than mechanical flow switches.
TDFS Advantages over Mechanical Flow Switches
• No paddles or vanes to break off into the flow
• No jams or material stopping the paddle movement
• No seals on movement assembly to wear or leak
• Low pressure drop, only needs to be 10% into the flow (e.g. 1/8˝ for 3/4˝
schedule 40 pipe)

Series FTS Thermal Flow Switch is especially designed, for all types of cooling systems,
as a reliable alternative to failure prone mechanical flow switches. The thermal flow switch
continually samples the temperature of the coolant and adjusts the low flow setpoint
automatically, providing a solid state switch should the coolant flow rate fall below the
setpoint value. In addition, the thermal flow switch will provide an alarm output should the
coolant temperature rise above acceptable levels. You have double protection with the FTS.

Series DFT Flow Transmitters use a segmented wedge differential producer to measure
flow rates as related to pressure to monitor process fluids. The segmented wedge provides
a simple and reliable restriction for sensing flow as related to pressure differential. The
sensor can be mounted in any position and allows the designer to install it in any orientation:
horizontal, vertical or inverted. The sensor is offered with three flow measuring ranges: 0.55, 1-10 and 1-15 GPM and three electrical output signals: 4-20 mA, 1-5 VDC and 1-10 VDC.
The sensor offers low-cost precision with a measuring accuracy of ±2% of full-scale range
and repeatability of ±0.5%.

FLOW
The SFI-100T is a low cost and durable flow transmitter that combines our popular
100 Series Sight Flow indicator with our A-711T output sensor. The SFI-100T sight flow
indicator is constructed of a robust, solid brass body and a tempered glass window. A bright
red impeller is featured for great visual indication of flow through the window. The front
window can be easily unscrewed to clean out the sight flow indicator. Ideal for outdoor
applications, the flow transmitter is weatherproof and unaffected by UV light.
The A-711T output sensor has a VDC output with pulsing for flow totalization and a
proportional frequency change for flow rate. For added versatility there are two output
choices of 5 VDC or a VDC equal to the input power supplied. The output is compatible with
digital rate meters/totalizers and other electronic systems. Great for use in monitoring
water flow especially in chillers.

The Series PFT is a paddlewheel flow sensor used to monitor liquid flow rates in pipes
from 1-1/2 to 40˝ with just one size adjustable sensor. A square wave output signal is
generated with frequency proportional to flow velocity. Multiple wetted material choices
offer application versatility. The PFT is ideal for monitoring water flow rates in irrigation
systems and building automation cooling systems.
The PFT uses inductive sensing to sense the blades of the impeller as they rotate. Sensor
technology does not use magnets allowing low flow rate monitoring and no concerns with
magnetic material in the flow. Paddlewheel, shaft and bearings are easily field replaceable.

The Series WMT Multi-Jet Water Meters are ideal for commercial and industrial
applications. The multi-jet design allows simplicity and accuracy with wide flow ranges,
even in low flow applications. The meter is designed for long service life and relatively
maintenance-free operation, even under adverse conditions. The magnetically driven,
hermetically sealed register will not leak or fog and is completely separated from the water.
The reed switch is activated by a magnet on the dial which is directly proportional to the
flow rate. The output is perfect for remote monitoring of flow rate or flow totalization and
can interface with PLC’s, counters, data loggers, and SCADA systems.

The Series UXF3 Ultrasonic Flowmeter Converters are paired with
Series SX1 or SX2 sensors in order to utilize the transit-time measure method.
Thanks to microprocessor-based electronics, the flowmeter can easily be
configured from the front keypad to specific applications. The flowmeter is
suitable for liquid flow measurements for pipes from 1/2 inch to 19.5 feet
diameter. The accuracy of this flowmeter falls within ± 1% of the flow rate. The
UXF3 also provides excellent resistance against aerated flow such as sludge,
raw sewage, and bubble contained flow. The multilingual display supports a
variety of language choices. The combination of the easy to read LCD screen
and front panel buttons along with the variety of language selections makes this
flowmeter very user friendly. This flowmeter incorporates the latest electronics
and high-speed digital signal processing technologies (32 bit MPU), realizing

is used to calculate the flow velocity. This meter is a clamp-on type ultrasonic
flowmeter for permanent use and is ideal for clean liquids containing no air
bubbles such as pure water. The easy-to-use compact and lightweight design is
intended for integration into mechanical devices. The adoption of a sound
velocity measurement system, which calculates sound velocity from the transit
time, keeps the flowmeter unaffected by the temperature and the pressure of
the fluid to be measured. Additionally, with the use of a high-speed transit time
processor, the system cycle is 0.2 seconds and applicable to short batch
processes.

PRINCIPLES OF OPERATION
The sensor head of the Thermal Dispersion Transmitter contains two PT-resistors.
One of them is measuring the temperature of the media, while the other is heated
by an attached heating resistor. The temperature difference between the two PTresistors is predetermined and a control circuit keeps this temperature difference
constant. The flow of the media cools the heated PT-resistor proportional to the
speed of the flow, this results in a linear output signal proportional to the flow speed.

The Series TDT is an excellent alternative to turbine and paddlewheel insertion flow
meters, with the ability to deliver high accuracy over a wide range of pipe sizes. This unit
has the same insertion mounting into a 1-1/2˝ NPT but no moving parts to wear, break, or
clog. This transmitter has available extensions that can be used for pipes sized up to 75˝
in diameter. The TDT Dispersion Transmitter measures even very low flow rates due to
the applied calorimetric principle, and can be used for the metering of all fluid media such
as: water, oil, aggressive media, paste, glue, sludge, grease, etc. Optional titanium allows
this transmitter to be used with an even wider range of corrosive media, and the optional
output allows the user to measure both flow and temperature. When deciding on the correct
length, use the 1/7th law (the TDT’s probe length needs to measure 1/7th of the pipe
diameter).

FLOW
The Series TDMT Flow Meter is for use in industrial applications, and can be easily
installed virtually non-intrusively into any pipe. This non-intrusive installation allows flowsensing without obstruction of the pipe diameter. It is completely encapsulated in epoxy
resin and is compact, rugged, shock and vibration resistant. It provides proven reliability
and long-term stability, even under the harshest environmental conditions. The TDMT is
made of stainless steel with a titanium option making it resistant to aggressive media. In
addition to its small and compact size, the TDMT also comes with a choice of a 1˝ unit with
1˝ NPT union nut or a 1-1/4˝ unit with 1-1/4˝ union nut, as well as available extensions
that can be used for pipes sized up to 10˝ in diameter. With an optional temperature
output, this meter provides the user with a very broad range of usage. When trying to
decide on the correct length, use the 1/7th law (the TDMT’s probe length needs to be
1/7th of the pipe diameter).

Program, record, analyze, and control flow rates of various gases with Series DMF
Digital Mass Flow Controller. Controllers are designed with straight tube sensors with
restrictor flow elements to ensure laminar gas flow for accurate and repeatable results.
Series DMF are unaffected by temperature and pressure variations.
Controllers can be programmed for various control functions including flow set point,
totalizer, stop totalizer, totalize from preset flow, stop and preset total, auto zero, and more.
Auto zero feature utilizes an automatic balancing circuit that virtually eliminates drift of
zero and span. In addition, Series DMF controllers have two dry contact closures to operate
pumps, valves, or other process equipment.
The Series DMF features an auto tune function to optimize control response for a specific
gas under actual process conditions. Self diagnostic tests are run at power up to ensure the
controller is in optimum working condition. Calibration information for up to 10 gases and
conversion factors for up to 256 different gases are stored in memory. High and low gas
flow alarm limits are programmed via RS-485 interface. Software supports programmable
flow modes, allowing execution of custom programming of up to ten steps.
