The FSA-Series transmitters sensing principle is based on differential pressure to ensure extremely fast response time (less than 10ms) and allow for precise flow measurement. Available in three flow ranges up to 27GPM, the transmitters feature a 4-20mA analog output, are fitted with a 4-pin M12 quick disconnect and are available with 3/4-in. or 1-in. FNPT process connections. The integrated check valve design allows the sensor to be mounted vertically or horizontally. The flow transmitters are IP65- and IP67-rated and are UL, CE and ROHS compliant.
