Flo-tech turbine ow sensors measure the ow rate of hydraulic uid and compatible liquids. Built to
withstand rigorous hydraulic applications, these ow sensors are available in anodized aluminum and zinc
plated Stressproof® steel bodies. Port types vary by body material, but include a choice of SAE, BSPP, Code
61 and Code 62, 4-bolt anged options.
Typical applications for the turbine ow sensors include:
• Fluid characteristic measurement on test stands
• Stationary hydraulic system monitoring
• Feedback for hydraulic system control
• Advance warning of impending component failure
• Mobile hydraulic system diagnosis
Flo-tech oers four dierent ow sensor models. Each of these models is available in a wide selection of
ow ranges and port sizes.
Turbine ow sensors measure the ow rate of hydraulic uid and compatible liquids. As uid ows through
the sensor it turns the turbine rotor, and as the turbine blades pass the magnetic pick-up a frequency
signal is generated. This frequency signal is proportional to the ow rate and can be transmitted to Flotech’s digital displays or converted to an analog output. Optional sensors allow measurement of pressure
and temperature.

This product should be installed and serviced by technically qualied personnel trained in maintaining
industrial class ow instrumentation and processing equipment.
CAUTION
Read instructions thoroughly before installing the ow sensor. If you have any questions regarding
product installation or maintenance, call your local supplier or the factory for more information.
WARNING
Do not use male pipe threads (NPT) into SAE straight thread ports. Using male pipe threads (NPTF) with
a ow sensor possessing SAE straight thread O-ring ports will not create a proper seal and is potentially
dangerous. Pipe threads inserted into an SAE straight thread port only allow the engagement of one
or two threads. No amount of tightening or thread seal will stop the leaking or make the installation
safe. Failure to follow these instructions could result in serious personal injury or death and/or damage
to the equipment.
Installation Recommendations
The in-line ow sensor is a simple device to install. However, the following measures are recommended for
reliable, trouble-free operation:
DO - Provide at least 10 port diameters of upstream straight pipe with no obstructions to the ow sensor
and at least 5 diameters of downstream pipe. The pipe should be of the same diameter as the nominal
port size.
Example:
An FSC-1000 has a one inch (25.4 mm) port. The unobstructed upstream length should be at least 10
inches (254 mm) and the downstream length should be at least 5 inches (127 mm).

Installation & Operating Instructions
DO - Choose a position for the ow sensor that will not be at the lowest level in the system. Placing the
ow sensor at a higher elevation in the system will avoid collection of debris, sediment and dirt in the ow
sensor.
DO - Use a lter. All applications should be ltered to at least 40 micron.
DON’T - Locate a ow sensor directly in-line with the outlet of a pump, as pressure pulsations can react
with the turbine. Locate the sensor after another component, observing the 10 port diameter rule.
DON’T - Adjust the magnetic pick-up on the ow sensor. This is calibrated at the factory. Further adjustment
will cause a decrease in performance or damage to the sensor.
DON’T - Exceed the working temperature range of –4 °F to +300 °F (–20 °C to +150 °C). Higher
temperatures will damage the magnetic pick-up and lower temperatures will limit the rotation of the
turbine.

The 4-20 mA output can drive auxiliary devices (resistive
loads) such as displays, recorders and computers, provided
that the voltage supplied by the power supply is adequate.
Devices must be wired in series with the F to I converter
and power supply. The voltage drop across the load(s) and
the 6 Vdc minimum needed to drive the F to I converter
determine the minimum voltage required from the power
supply.
Determine the necessary voltage required to adequately
drive the F to I converter and auxiliary device(s).
The F to I converter acts as a current controlling device.
Thus, the current output remains the same even if the power
supply voltage uctuates or the load resistance changes.
The current varies only with respect to the ow rate from
the turbine ow sensor, as long as the voltage drop across
the F to I converter is at least 6 Vdc.
The load(s) in the circuit will generally have some electrical
resistance, 100 Ohms for this example. The 4-20 mA loop
current will produce a voltage drop across each load. The
maximum voltage drop across a load(s) will exist when
the loop current is 20 mA. The power supply must provide
enough voltage for the load(s) plus the 6 Vdc minimum
insertion loss of the F to I converter.

At 20 mA loop current, the voltage drop across the load(s)
Subtract 6 volts from the 24 volt source to determine that
18 volts is available to power the F to I converter. The 18
volts is within the specified 10 to 30 volt range and is
sufficient to power the F to I converter.
At 20 mA loop current, the voltage drop across the load(s)
Subtract 20 volts from the 24 volt source to determine that
4 volts is available to power the F to I converter. The 4
volts is below the specified 10 to 30 volt range and is not
adequate to power the F to I converter. If for example, the
power supply voltage was 30 volts instead of 24 volts, the
voltage available to power the F to I converter would be 10
volts and within the specified range.

Installation & Operating Instructions
V. OPERATION
General
WARNING
Do not exceed allowable pressure ratings. Pressure in excess of the maximum allowable ratings may
cause the turbine body to fail. Failure to follow these instructions could result in serious personal injury
or death and/or damage to the equipment.
DO - Allow uids to warm to operating temperatures before critical measurements are taken.
DO - Maintain a ooded condition in the ow sensor at all times. Air and turbulence will result in erroneous
readings.
DON’T - Exceed the working temperature range of –4 °F to +300 °F (–20 °C to +150 °C). Higher
temperatures will damage the magnetic pick-up and lower temperatures will limit the rotation of the
turbine.
Flow Sensors with IFC Option
As soon as power is applied, the IFC will begin to output an analog value representative of the measured
frequency from the turbine meter.
Refer to the wiring diagram that corresponds to the IFC being utilized. See pages 11 and 12.
VI. MAINTENANCE
WARNING
Always disconnect the primary power source before inspection or service. Failure to follow these
instructions could result in serious personal injury or death and/or damage to the equipment.
1. A schedule for maintenance checks should be determined based upon environmental conditions and
frequency of use. Inspect at least once a year.
2. Perform visual, electrical and mechanical checks on all components.
a. Visually check for undue heating evidenced by discoloration of wires or other components,
damaged or worn parts, or excessive corrosion of the device.
b. Electrically check to make sure that all connections are clean and tight and that the device is
