Product introduction

Ultrasonic Doppler Velocity Meter is a device for measuring the flow velocity of water in pipes, channels or rivers. It is mainly used in the following areas:

·Flood disaster monitoring

·Sewage Disposal

·Natural rivers

·Municipal water supply and drainage

·Water loss/infiltration monitoring

·Irrigation process monitoring

·Research on estuaries and tides

·Fishery/Water Conservancy

·Coastal erosion research

·Underdrain process monitoring

·Road drainage monitoring

·The canal process research

·River flow monitoring

Technical parameters

Structure: split type;

Measurement types: flow rate, water depth, (water temperature measurement is an optional function)

Purpose: online measurement

Flow velocity measurement range (water depth above sensor: 20cm):

The positive flow velocity is +0.03m/s～+5.00m/s;

The negative flow velocity is -1.00m/s～-0.03m/s (optional);

Other flow rate ranges can be customized.

Deep range: 0.02～3m, 0.02～10m (please confirm the maximum water depth before ordering);

Flow velocity accuracy: ±1% (detection accuracy submitted by the Ministry of Water Resources);

Flow velocity accuracy: ±1～3% (measurement accuracy will change due to the influence of on-site working environment);

Water depth measurement resolution: 1mm

Water depth measurement accuracy: 0.5%;

Temperature range: 0～60ºC; resolution: 0.1ºC;

Flow range: no flow measurement function

Working voltage: conventional 12～13VDC, the lowest working voltage is 10.3VDC, the highest is 14VDC.

Output signal: RS485 MODBUS protocol;

Wireless transmission (optional): GPRS type RTU wireless transmitter

Sensor cable length: 10 meters;

Types of tested waterways: pipes, channels, natural streams, rivers;

Liquid pH requirement: PH value is between 6-8.

Liquid temperature requirement: 0～60℃, non-solidification

Liquid pressure requirement: 1 standard atmospheric pressure in natural environment

Tips: 1. The flow rate cannot be measured when the water is solidified or close to solidification.
