The measurement method of the open channel flow monitoring station introduced in this article is: hydraulic structure method water level method
Water level method: Measurement is achieved by measuring the upstream (or upstream and downstream) water level of a water measuring structure and converting it into flow rate through empirical formulas or experimental curves. The water level flowmeter requires the construction of a water measuring structure. For example: rectangular groove, triangular weir plate, Bacher groove, etc. Water Testing Home offers a diverse range of products, which can be customized according to customer needs, on-site environment, and equipped with different products.
1、 Integrated radar water level gauge
1) System composition
2) Product Introduction
SCJ-LD40 is a high-precision, ultra-low power non-contact integrated radar water level gauge (open channel flowmeter). The product integrates telemetry terminal acquisition and transmission system (RTU), high-precision liquid level gauge, and 4G/NBIOT wireless transmission signal configuration; The protection level is IP68, and the non-contact measurement design ensures that it is not affected by corrosion, temperature, humidity, or harsh environments during measurement. The unique optimized algorithm makes its measurement data more stable and accurate.
3) Installation diagram
Ultra low power consumption design, built-in battery, and up to five years of battery life without the need for additional solar panels. Can be paired with hydraulic structures such as rectangular slots, triangular weir plates, and Bacher slots, equipped with telemetry terminals to calculate flow rates based on the unique hydraulic model of the water surveyor.
2、 Split type radar water level gauge
1) System composition:
2) Product Introduction
The SCJ-LD40 radar water level gauge adopts a 24G microstrip planar array antenna and frequency modulated continuous wave (FMCW) technology. The product has high measurement accuracy, low power consumption, small size, light weight, strong resistance to environmental interference, and has good reliability and maintainability. Working 24/7, suitable for unmanned monitoring in the wild or mountainous areas, capable of automatically measuring and calculating data, high stability, long service life, and maintenance free; Adopting the principle of microwave reflection, it has strong anti-interference ability and measurement data can reach millimeter level. It is not affected by weather, air pressure, region, and other factors, and can operate in various complex sites. It can also adapt to different environments at any time after changing scenes.
3) On site case:
1) The radar water level gauge is matched with a rectangular groove and converted into flow rate through a remote sensing terminal of the water measurement company~
2) The radar water level gauge is matched with a triangular groove, and the flow rate is converted through the remote sensing terminal of the water meter~
3) The radar water level gauge is matched with a Bachel tank and the flow rate is converted through a remote sensing terminal of the water measurement company~
