The Pyxis FS-100 Ultrasonic Micro Flow Meter operates on the principle of transit time difference with a measurement range of 0 to 3,000mL/min and a resolution of 1mL. In this flow measurement method, the propagation speed of ultrasonic waves downstream is faster than upstream, and the transit time difference is directly proportional to the flow rate.

The FS-100 series is suited for flow measurement and is offered with a CPVC liquid end material of construction, for standard water. The sensor's advanced PCB design offers built-in temperature compensation to eliminate the effect of temperature with instantaneous, accumulated, and controlled water flow based on user setpoint within the sensor itself. The flow meter is powered by a 24VDC / 1W power supply and provides both 4 to 20mA and RS-485 Modbus output signals for connecting to any OEM controller, PLC, or DCS.

Specifications include fluid temperature 40-120ºF, operating temp 32-122ºF, inlet pressure 7.25-100psi, 1/4in OD inlet and 1/2in FNPT outlet, 5mm flow path ID. Accuracy max error ±1% of value. IP65 protection, CE/RoHS compliant. The 1.44in color display provides local readout.
