SPDV200F Doppler Open Channel Flow Meter

SPDV200F Doppler Open Channel Flowmeter can obtain the velocity of the fluid by measuring the Doppler frequency shift of the sound waves scattered by the moving particles in the fluid. Combined with the built-in pressure water level gauge, the velocity area method can be used to measure the flow of the liquid. The display can designed with handheld meter or wall-mounted display meter.

SPDV200F Doppler Open Channel Flow Meter is a meter for measuring the velocity and flow of water in natural waters, channels and pipelines. The flowmeter is divided into two parts: sensor and host, and the middle part is connected by cable. It can measure the velocity and flow of water in channels and rivers, and the water level is more than 20 cm higher than the sensor. It can measure the flow rate and flow rate of water in pipelines and underground channels. The water level should be more than 20 cm higher than the sensor, and the inner diameter of the pipeline should be ≥ 500 mm.
