Product Introduction
HD-DPF420 ultrasonic Doppler flow meter is suitable for river, nullah, pipeline and other scenarios to monitor the flow rate, water level, temperature, instantaneous flow rate and cumulative flow rate of the waters online.
The instrument adopts ultrasonic Doppler principle to measure the flow velocity, ultrasonic time difference method or hydrostatic pressure method to measure the water level, and calculates the flow rate by setting the cross section. Doppler flow meter has the characteristics of compact structure, no rotating parts, long life, easy to use, maintenance-free, and its widely used in sponge city, water supply/drainage network, black smelly water body, natural river, nullahs, reservoirs, flow field analysis of scientific research, liquid level detection and other scenarios.
Functional features
※ The sensor supports the measurement of instantaneous flow, cumulative flow, flow rate, water level and water temperature.
※ Strong adaptability, can measure correctly even under extremely low flow conditions.
※ Supports flow accumulation in a variety of channel types, such as rectangular, trapezoidal and circular channels.
※ Flow velocity range up to 10m/s, capable of measuring flow under high flow conditions during floods.
Accurate measurement, flow rate measurement accuracy is accurate to 1mm/s error.
※ Support RS485 communication interface, MODBUS RTU communication protocol, can also be customized protocol.
※ With data saving function, can save the setup parameters and cumulative flow rate value in the case of long-term power failure.
※ IP68 protection level, waterproof and dustproof, long service life.
※ Flow rate area measurement, Doppler flow principle, intelligent integration algorithm, more accurate measurement.
