It is a wall-mount, clamp- on type ultrasonic flow meter which uses the transfer time technology. Designed using FPGA chip and low-voltage broadband pulse transmission.

Both Clamp on type sensors and Insertion type sensors are available. Has a 240*128 back lit LCD with 4 line menu display and also the clear, user-friendly menu selections make flow meter more simple and convenient to use.

Daily, monthly and yearly totalized flow. Parallel operation of positive, negative and net flow totalizes with scale factor (span) and BTU Capacity. While the output of totalize pulse and frequency output are transmitted via relay and open collector.

Could add the RTD model and temperature sensor become an energy meter to monitoring the energy use, help to save the energy.

Ultrasonic flowmeter widely application in HVAC, water treatment, irrigation.
