Sierra Instruments appreciates your choosing our product for your liquid level or liquid/gas flow
switching application. We are committed to providing reliable, quality instrumentation to our customers.
To ensure the maximum and intended benefit of this instrument, we encourage you to read this brief
operation and maintenance manual in its entirety prior to unpacking and installing the unit.
The following precautions should be noted immediately:
φ
WHEN INSTALLING YOUR SIERRA INNOVA-SWITCH™ INTO A PIPE OR VESSEL USE A 1
1/8 INCH (28.575mm) OPEN-END OR ADJUSTABLE WRENCH TO TIGHTEN AT THE HEX
FLATS OF THE MNPT OF A STANDARD SWITCH. (IF YOU HAVE A NON-STANDARD
SWITCH AN ALTERNATE SIZE WRENCH MAY BE REQUIRED). DO NOT USE THE
INSTRUMENT HEAD TO TIGHTEN THE SWITCH TO THE MOUNTING PORT. ROTATION
OF THE INSTRUMENT HEAD WITH RESPECT TO THE SENSOR BODY CAN CAUSE
INTERNAL WIRING DAMAGE (SEE FIGURES 1).
φ
THE SWITCH BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PARALLEL TO
THE LEVEL BEING DETECTED WHEN THE SENSOR IS INSTALLED HORIZONTALLY FOR
POINT LEVEL APPLICATIONS. LIKEWISE, FOR FLOW APPLICATIONS, THE SWITCH
BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PERPENDICULAR TO THE
FLOW BEING DETECTED. DUE TO THE PIPE THREAD MOUNTING, IT MAY BE
NECESSARY TO MAKE A TRIAL FIT, ADD OR REMOVE TEFLON TAPE OR OTHER PIPE
THREAD SEALANT, AND REINSTALL TO ACHIEVE A SATISFACTORY SEAL WITH THE
SENSORS PROPERLY ORIENTED. FOR VERTICAL INSTALLATION OF SENSORS FOR
POINT LEVEL DETECTION THE ORIENTATION MAKES NO DIFFERENCE. PROPER
ORIENTATION IS MARKED ON THE SWITCH BODY FOR REFERENCE (SEE FIGURE 5).
φ
A GROUND WIRE MUST BE ATTACHED TO THE GROUND SCREW LOCATED INSIDE THE
INSTRUMENT ENCLOSURE FOR PROPER OPERATION. FOR CENELEC/CE OPTION THE
GROUND SCREW IS LOCATED OUTSIDE THE BODY OF THE INSTRUMENT ENCLOSURE
(SEE FIGURE 6).
φ
BE SURE TO APPLY THE PROPER VOLTAGE AS CONFIGURED AT THE FACTORY. DO
NOT APPLY 115 VAC TO 24 VDC VERSIONS OR 24 VDC TO 115 VAC VERSIONS.
(LIKEWISE 230 VAC).
φ
FOR OPTIMUM OPERATION, CALIBRATION MUST BE ACCOMPLISHED AT ACTUAL
PROCESS TEMPERATURE AND PRESSURE CONDITIONS IN GASES AND AT ACTUAL
PROCESS TEMPERATURE CONDITIONS IN LIQUIDS.
φ
TO ENSURE ACCURATE CALIBRATION AND AVOID SET POINT DRIFT, IT IS IMPERATIVE
THAT A MINIMUM OF 10 MINUTE WAIT BE OBSERVED AFTER POWER IS APPLIED TO
ALLOW THE SENSOR TO WARM-UP TO THE AMBIENT FLUID TEMPERATURE.
LIKEWISE, WHEN ADJUSTING THE ZERO, SPAN, AND SET POINTS POTS, A MINIMUM
iii
Sierra Instruments
Innova-Switch™ Instruction Manual
OF 30 SECONDS SHOULD BE OBSERVED TO ALLOW FOR STABILIZATION OF
TEMPERATURE.
φ
DO NOT SANDBLAST OR ABRASIVE CLEAN THE SENSING PROBES. THE SENSING
PROBES COULD BE DAMAGED BY ABRASIVES.
„
ALL DIMENSIONS GIVEN IN THIS MANUAL ARE IN INCHES (AND MILLIMETERS).
If you have any questions prior to or during installation and calibration, please do not hesitate to call the
factory for assistance. We want to ensure the very best possible installation and operational results for

INTRODUCTION
The Sierra Innova-Switch™ is the state-of-the-art in gaseous and liquid flow switching or
liquid level control. Flow or level detection is accomplished by using a high resolution
thermal differential technique. The sensor wetted parts are of durable 316L series
stainless steel, all welded construction with no moving parts. The switch is easy to install
and adjust, giving reliable, low maintenance performance in the most demanding
applications.

DESCRIPTION
The Innova-Switch™ uses a thermal differential technique to sense changes in the heat
transfer characteristics of a media. Figures 1A and 1B show the outline of the InnovaSwitch™. The sensor consists of a pair of matched, Resistance Temperature Detectors
(RTD's) encased in twin 316L series stainless steel tubes. One RTD is self-heated using a
constant DC current. The other RTD is unheated to provide an accurate process
temperature reference. The thermal differential created between the heated and reference
RTD pair is a function of the density and/or velocity of the media with which the sensor is in
contact. Other physical properties may have a secondary effect as well. The differential is
greatest at a no flow (or dry) condition and decreases as the rate of flow increases (or as a
liquid quenches the sensor/wet condition).
The Sierra Instruments’ sensor excitation method relies on constant current to the heated
and reference sensors. Thus power to the heated sensor is not constant but changes
linearly with temperature as the sensor resistance changes. Temperature compensation is
accomplished by using the amplified reference sensor voltage which also changes linearly
with temperature, as a dynamic reference. During calibration dry/no flow and wet/full flow
conditions are impressed across the trip point potentiometer. Since this reference is not
fixed but is set with respect to the reference sensor voltage, as temperature changes the trip
point potentiometer voltage changes with temperature exactly the same as that of the heated
sensor voltage with which it is being compared. Thus full temperature compensation is
achieved with non constant power.

Innova-Switch™ Instruction Manual
LEVEL SWITCHING
The thermal differential created between the heated and reference unheated RTD pair is a
function of the liquid or gas medium with which the sensor is in contact.
The point level measurement application uses the heat transfer differences between two media
to detect liquid level. For example, air has a relatively poor heat transfer characteristic so the
heated sensor will become relatively hot. If the sensor is then immersed in water, the relatively
high heat transfer characteristics of water will cool the heated RTD surface causing a decrease
in the signal output.
This same rational applies for any two media in contact with the sensor. Each medium will have
its own characteristic heat transfer properties. As long as there is a reasonable difference in the
heat transfer properties between the two media, the Innova-Switch™ can discriminate between
them. Figure 2A shows the relative signal output of the Innova-Switch™ sensor to a range of
different media. The maximum difference in output occurs between vacuum and liquid metal.
However, a significant difference occurs between water and hydrocarbon liquids so the InnovaSwitch™ can be used to detect a water/hydrocarbon liquid-liquid interface. In general, the
interface between any two media with differing heat transfer properties can be detected.

FLOW SWITCHING
Most mass flow monitoring techniques calculate mass indirectly by measuring volumetric flow
such as gallons per minute or cubic cm per second, then either measure density separately or
calculate it from temperature measurements of the fluid and, finally, combine density and
volumetric flow to obtain mass flow. The Sierra thermal-differential technique is one of two
methods that directly measure the mass flow. For ease of comparison most flow applications
are presented in terms of velocity which is independent of the flow cross sectional area (i.e. feet
per second (FPS)). The true mass flow equivalent would be FPS multiplied by density but for
simplicity FPS is used and density effects are ignored. This is normally not critical for flow
switching applications.
When the sensor is inserted into a liquid or gas the heated RTD is strongly affected by the
velocity of the medium. Flow past the heated RTD changes the heat transferred from the
surface of the sensor. This cooling effect reduces the temperature of the sensor. The
Innova-Switch™ compares this change to a preset flow trip point to switch the output. Figure
2B shows the model 615 signal change vs. flow rate for air, light hydrocarbon liquids, and
water. The signal change vs velocity has the same general shape for all three media but the
change is larger for air and the sensitive range is different for each. For air and most

gaseous media the range is 0.1 to 500 feet per second (FPS). For most liquid media the
range is 0.01 to 5 FPS (Hydrocarbons) and 0.01 to 2.5 FPS (water). Appendices in section
9.0 contain flow conversion information to facilitate conversion from various units and pipe
dimensions into flow velocity in feet per second.

Flow across the tips decreases
the thermal differential because
of the higher heat transfer of
flowing fluids. This differential is
compared with the trip point.
When flow is above the trip point
the differential is smaller than at
the set point and the relay and

Figure 3.A shows a block diagram of the Innova-Switch™.
Once the switch is set to respond to the minimum and maximum flow rates (or wet vs. dry
conditions), the trip point is set by adjusting the Trip Adjust Potentiometer. Solid state
electronics transform the flow (or wetting) induced temperature differential into a voltage that
is compared to a control voltage. Matching voltages cause actuation of a relay to indicate a
change in state (flow vs. no-flow or dry vs. wet).

OPERATION AND CALIBRATION OF THE INNOVA- SWITCH™ MODEL 615 FOR
FLOW APPLICATIONS
4.1
Pre-Operational Check
With the switch installed and process conditions at no-flow, the following procedure can be
used to verify preliminary operation.
4.1.1
Remove the instrument enclosure cover by turning counter clockwise (ccw) to expose the
Innova-Switch™ electronics.
4.1.2
Turn on power at its source.
4.1.3
Observe that either the red or green LED comes on.
4.1.4
If neither lamp illuminates refer to the trouble shooting Section, 6.2.
4.2
L.E.D. and Relay Status Logic (Fail-safe)
4.2.1
The L.E.D.s (Red; Green) are an indication of the sensors status (ie. flow below the setpoint
or flow above the set point) and are not affected by the position of the failsafe jumper J-2.
The failsafe jumper J-2 changes the relay activation status allowing the user to select the
failsafe power off condition most appropriate to the application. Refer to the tables below
that show the logic conditions between the sensors, L.E.D. lights, relay coil and contacts for
each position of the failsafe jumper J-2.
4.2.2

CALIBRATION – FLOW
**IMPORTANT**
FOR OPTIMUM OPERATION, CALIBRATION MUST BE ACCOMPLISHED AT
ACTUAL PROCESS TEMPERATURE AND PRESSURE CONDITIONS IN GASES
AND AT ACTUAL PROCESS TEMPERATURE CONDITIONS IN LIQUIDS.
See Figures 8.0 and 9.0 for location of potentiometers and LEDS on electronics PCB.
4.3.1
CALIBRATION PROCEDURE FOR FLOW SWITCHES
1.
Remove the instrument enclosure lid by turning ccw.
2.
Apply power to FS4200. Allow 10 minute warm-up.
3.
Ensure that the pipeline is filled with fluid and at no or minimum flow.
4.
Set the trip adjust pot to zero fully counterclockwise (fully ccw).
5.
Adjust the zero adjust pot so that the Red LED just does illuminate. This is a 25 turn pot. If the
Green LED is on, turn the pot ccw. If the Red LED is on, turn the pot clockwise (cw).
6.
Toggle the zero adjust pot back and forth until the switching point is well defined. Leave the Red
LED illuminated.
7.
Adjust the liquid or gas flow to maximum velocity. Insure that the flow is homogenous, constant
and free of bubbles if a liquid.
**NOTE**
The flow rate (maximum) should be at least 5 fps (Hydrocarbons), 2.5 fps (water), or 500 fps
(gas/air) if possible for best calibration. It is possible to achieve a 5 fps set point in water if a
span of 7 fps can be achieved.
TO ENSURE ACCURATE CALIBRATION AND AVOID SET POINT DRIFT, IT IS
IMPERATIVE THAT A MINIMUM OF 10 MINUTE WAIT BE OBSERVED AFTER POWER IS
APPLIED TO ALLOW THE SENSOR TO WARM-UP TO THE AMBIENT FLUID
TEMPERATURE.
LIKEWISE, WHEN ADJUSTING THE ZERO, SPAN, AND SET POINT POTS, A
MINIMUM OF 30 SECONDS SHOULD BE OBSERVED TO ALLOW FOR STABILIZATION
OF TEMPERATURE.
8.
Set the trip adjust pot to 100 (fully cw).
9.
Adjust the span adjust pot so that the Green LED just does illuminate. This is a 25 turn pot.
If the Green LED is on, turn the pot cw. If the Red LED is on, turn the pot ccw.
10. Toggle the span adjust pot back and forth until the switching point is well defined. Leave the
Green LED illuminated.
11. If the switch is to be used for flow - no flow, set the trip adjust pot to 50 and go to step 14. (Note:
This adjustment can be set for tripping points between 10% and 90% of the span from no flow to
max flow).
12. A more exact flow rate setting may be made by establishing the flow at the desired rate with a
separate flow meter and proceeding to step 13, to establish the trip point.
13. Adjust the trip adjust pot to obtain a trip as exhibited by an LED illumination.
24
If a trip on
Sierra Instruments
Innova-Switch™ Instruction Manual
decreasing flow is desired set for Red LED illumination. If a trip on increasing flow is desired set
for Green LED illumination.
14. Verify that the switch will reset by returning the actual product flow to the maximum or minimum
flow rates.

OPERATION AND CALIBRATION OF THE INNOVA-SWITCH™ 615 SERIES SWITCH
FOR POINT LEVEL APPLICATIONS
5.1
PRE-OPERATIONAL CHECK
The switch is installed and the product level is below sensor level (dry), the following
procedure can be used to verify preliminary operation.
1. Remove the instrument enclosure cover by turning counter clockwise to expose the
LS3200 Switch electronics.
2. Turn on power at its source.
3. Observe that either the red or green LED comes on.
4. If neither lamp illuminates refer to the trouble shooting Section, 6.2.
5.2
L.E.D. AND RELAY STATUS LOGIC (FAIL-SAFE)
5.2.1
The L.E.D.s (Red and Green) are an indication of the sensors status (ie. dry or wet) and are
not affected by the position of the fail-safe jumper J-2. The fail-safe jumper J-2 changes the
relay activation status allowing the user to select the fail-safe power off condition most
appropriate to the application. Refer to the tables below that show the logic conditions
between the sensors, L.E.D. lights, relay coil and contacts for each position of the fail-safe
jumper J-2.
5.2.2
NORMAL OPERATION (AS SET AT FACTORY)
The switch comes configured from the factory with the following operation with the J-2 jumper

CALIBRATION - LEVEL
Using Figure 10.0 as a location guide adjust the system as follows:
1.
Remove the instrument enclosure lid by turning ccw.
2.
Apply power to the unit. Allow 10 minute warm-up.
3.
For optimum calibration results, wet sensor and drain but do not dry.
4.
Ensure that the tank liquid level is below the probe sensor tips.
5.
Set the trip adjust pot to zero, fully counterclockwise (fully ccw).
TO ENSURE ACCURATE CALIBRATION AND AVOID SET POINT DRIFT, IT IS
IMPERATIVE THAT A MINIMUM OF 10 MINUTE WAIT BE OBSERVED AFTER POWER IS
APPLIED TO ALLOW THE SENSOR TO WARM-UP TO THE AMBIENT FLUID
TEMPERATURE.
LIKEWISE, WHEN ADJUSTING THE ZERO, SPAN, AND SET POINT POTS, A
MINIMUM OF 30 SECONDS SHOULD BE OBSERVED TO ALLOW FOR STABILIZATION
OF TEMPERATURE.
6.
Adjust the zero adjust pot so that the Red LED just does illuminate. This is a 25 turn
pot. If the green LED is on, turn the pot counterclockwise (ccw). If red LED is on, turn
the pot clockwise (cw).
7.
Toggle the zero adjust pot back and forth until the switching point is well defined. Leave
the Red LED illuminated.
8.
Raise the level of the liquid to be detected until the probe/sensor tips are submerged
and wet (covered).
9.
Set the trip adjust pot to 100 (fully cw).
10. Adjust the span adjust pot so that the Green LED just does illuminate. This is a 25 turn
pot. If the Green LED is on, turn the pot cw. If the Red LED is on, turn the pot ccw.
11. Toggle the span adjust pot back and forth until the switching point is well defined. Leave
the green LED illuminated.
12. Adjust the trip adjust pot to 80 and the calibration is complete. Setting this pot to 80
gives an approximate equal trip time from wet to dry and from dry to wet. Setting this pot
closer to zero will speed up dry to wet trip time and slow down wet to dry trip time.
Setting this pot closer to 100 will slow down the dry to wet trip time and speed up wet to
dry trip time.
