Radar Flowmeter

Product description

A fully automatic flowmeter based on microwave technology. It adopts advanced K-band planar radar technology to measure the flow velocity and water level of water bodies in a non-contact way. According to the built-in software model and algorithm, it calculates and outputs real-time cross-section instantaneous flow and cumulative flow; it can be used for river channels, irrigation canals, and underground drainage pipes. Non-contact flow measurement is carried out in various occasions such as network, flood control and early warning; the product has the characteristics of low power consumption, high reliability, and convenient maintenance; the measurement process is not affected by factors such as temperature, sediment, river pollutants, and floating objects on the water surface.

Features

1. Non-contact measurement, combined with section parameters to calculate flow, not affected by wind, temperature, haze, sediment, floating objects, etc. With rainproof mode;

2. Applicable to a variety of measurement conditions, and can output measurement data of flow rate, water level, and flow rate;

3. Scalable array multi-point flow measurement, equipped with one set of flowmeter and multiple sets of velocity meters, and through the internal algorithm fitting of the flowmeter, the flow measurement of wide cross-section can be realized;

4. It is suitable for trapezoidal, circular, U-shaped, and other cross-sections, and the setting method of cross-section parameters is simple and convenient;

5. The convenient configuration software can conveniently configure the parameters according to actual needs to adapt to different use conditions.
