Ultrasoon open kanaal flowmeter
Ultrasoon open kanaal flowmeter
- The non-contact measurement method is used to measure the water level in the channel through an ultrasonic probe. This avoids direct contact with the fluid, thereby reducing the impact of fluid corrosion, impurities and other problems on the equipment.
- Supports multiple communication methods such as RS485 communication, GPRS wireless transmission and Ethernet wired transmission, which is convenient for integration with remote data management systems.
- Widely used in water volume measurement of natural water bodies such as rivers, channels, reservoirs, flow monitoring of urban drainage systems, sluice water level control, and water quality monitoring.
Productoverzicht:
Working Principle: The physical quantity directly measured by the open channel flow meter is the liquid level. When used for open channel flow measurement, a water measuring weir is installed on the open channel. The water measuring weir converts the flow in the open channel into the height of the liquid level. The instrument measures the water level in the water measuring weir, and then calculates the instantaneous flow according to the relationship between the water level and flow of the corresponding water measuring weir.
Use: Used in conjunction with the water measuring weir to measure the flow of water in the open channel. Mainly used to measure the flow of sewage treatment plants, sewage outlets of enterprises and institutions, and urban sewers.
Sollicitatie:
Urban drainage system: Ultrasonic open channel flowmeters can be installed in the open channel section of the urban drainage network to monitor drainage flow in real time. It helps urban drainage management departments know drainage conditions, prevent waterlogging, and optimize the operation of drainage facilities.
Sewage treatment: At the inlet and outlet of the sewage treatment plant, ultrasonic open channel flow meters are used to measure sewage flow, ensure the normal operation of sewage treatment facilities, and monitor the treatment effect.
Agricultural irrigation: In agricultural irrigation systems, ultrasonic open channel flow meters can be used to measure the flow rate in irrigation channels, helping farmers to allocate water resources scientifically and rationally and improve irrigation efficiency.
