Product Description
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.
Specification
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.
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.
