ProSense Mechatronic Flow Transmitters
ProSense FSA series mechatronic flow transmitters monitor liquid media and provide an analog output proportional to flow rate. The sensing principle uses differential pressure, ensuring very fast (<10ms) response time and precise flow measurement. Their immunity to rapid media temperature change makes these ideal for coolant flow applications.

FSA Series Flow Transmitters
The ProSense FSA Series flow transmitters monitor liquid media and provide an analog output proportional to flow rate for various flow applications.
The sensing principle is based on differential pressure
which ensures extremely fast response time and allows for a
precise flow measurement.
The transmitters are available in three flow ranges up to
FSA Series flow transmitters are ideal for applications
with rapid temperature changes or where fast response time is
required, such as:
Machine tool coolant flow
HVAC cooling water flow
Injection molding cooling water flow
Measure up to 27GPM (gallons per minute) in 3 models
Immune to rapid temperature changes of media
Fast response time of < 10ms
3/4" or 1" FNPT process connections
Integrated check valve design allows the sensor to be mounted horizontally or vertically
4-pin M12 quick disconnect

The flow sensor utilizes a spring-supported piston that
is lifted by the flowing medium.
By monitoring the piston position, the flow rate is
determined on the principle of differential pressure and is
converted into an analog output signal (4 to 20 mA).
The spring resets the piston to its initial position with
decreasing flow, allowing the sensor to be mounted in any
position (horizontally or vertically) and function as a check
The analog signal for water (20°C [68°F]) is
linear from 4.3 mA to 20mA (4mA = no flow).
For an output signal greater than 20mA, the flow rate is
above the final value of the measuring range.
