Features
Works on the multi-channel transit-time principle. The accuracy is 0.5%.
Wide bi-directional Flow range of 0.01 m/s to 12 m/s. Repeatability is less than 0.15%.
Low starting flow, super wide turndown ratio Q3:Q1 as 400:1.
3.6V 76Ah battery power supply，with lifetime over 10 years (measuring cycle: 500ms).
With storage function. Can storage both forward flow and backflow data 10 years (day, month, year ).
Hot-tapped installation, no pipe line flow interrupted.
Standard output is RS485 modbus, Pulse, NB-IoT, 4G, GPRS, GSM can be optional.
Two channels and four channels can be optional.
