FRM7000 Underground Pipeline Flow Meter

FRM7000 radar ultrasonic flow meter is an intelligent online flow and water level monitoring device primarily developed for applications in urban underground drainage networks and river/sea outfalls. The device integrates the application features of radar and ultrasonic flow measurement, enabling blind-zone measurement of flow and water level in complex underground pipe network conditions, both full and partial pipe scenarios. It is also easy to install and maintain.

The device integrates the application features of radar and ultrasonic flow measurement, enabling blind-zone measurement of flow and water level in complex underground pipe network conditions, both full and partial pipe scenarios. It is also easy to install and maintain.

Data is output via an RS485 interface using the standard MODBUS-RTU protocol.

The radar ultrasonic flow meter mainly consists of a radar flow module, an ultrasonic flow module, and a control unit.
