Product Description
Product Description
Introduction
Product Introduction The product is a kind of sensor that measures flow velocity and flow rate in
natural waters, channels or pipes. The flowmeter is divided into two parts: sensor and host, connected
by cable. To be able to measure flow velocity and flow rate in channels and rivers, the water level has
to be 20 cm higher than the sensor. To be able to measure flow velocity and flow rate in pipeline and
culvert, water level has to be more than 20 cm higher than the sensor, tubing inner diameter has to be ≥500 mm.

Operating Principle
The sensor is fitted with two energy converters, one for transmission, one for receiving. On the premise
that the sensor is facing the water flow direction, i.e.
countercurrent direction:
1.When water is static, the transmission and receiving frequencies are the same.
2.The faster the velocity is, the faster frequency the sensor receives signal, and it will be higher than
transmission signal.
3.The slower the velocity is, the slower frequency the sensor receives signal, and it will be lower than
transmission signal.
Page 1 of 39 On the premise that the sensor is on the water flow direction, i.e. current
direction:
1.When water is static, the transmission and receiving frequencies are the same.
2.The faster the velocity is, the faster frequency the sensor receives signal, but it will be lower than
transmission signal.
3.The slower the velocity is, the slower frequency the sensor receives signal, but it will be lower than
transmission signal.
Hardware and software can calculate water flow direction and velocity.
The sensor has to be installed facing the water flow directionTechnical Parameters Initials for Field Irrigation Doppler flowmeter | FIDF Model no. |
