Fuji FLR Ultrasonic Flow Meter Time Delta Series M-Flow PW

This flowmeter is a clamp-on type ultrasonic flow meter based on transit- time measuring method.

Making full use of the latest electrics and digital signal processing technologies, we realized the equipment with improved anti-bubble performance high accuracy.

The communication function (MODBUS: option) is also applicable.
