The new FS-100 series are state-of-the-art ultrasonic flowmeters that operate on the principle of transit time difference with a measurement range of 0 – 3,000 mL/min and 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 flow meter is perfectly suited for flow measurement and is offered in two liquid end materials of construction, for standard water and highly corrosive aqueous solution metering applications. The sensors 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 FS-100 series flow meter is powered by a 24 VDC/1 W power supply and provides both 4–20 mA and RS-485 Modbus output signals for connection to any OEM controller, PLC or DCS.
