The ultrasonic open channel flow meter uses ultrasonic waves to measure the water level in an open channel weir or flume in a non-contact manner, and then the microprocessor automatically converts it into the corresponding flow value. When measuring flow, the LCD screen displays the instantaneous flow and cumulative flow; when measuring liquid level, it displays the liquid level and upper/lower limit alarm indicators.

Note: Flange dimensions will vary depending on the transducer and will be notified in advance if there are any differences.
The meter adopts an EEPROM digital memory, which ensures that data in the instrument will not be lost after a power failure.
It is also equipped with explosion-proof probes specially designed for the petroleum and chemical sectors to meet the requirements of measuring sewage flow in explosion-proof areas of petroleum, chemical, and other sectors (explosion-proof grade: ExiaIIBT4), and is particularly suitable for flow measurement of oil-containing wastewater.
Matching with various national standard weirs or flumes, the ultrasonic open channel flow meter can be widely used for measurement or monitoring of total discharge volume of various channels, full pipes, non-full pipes, and various water qualities.
The measurement results and the sensor itself are not affected by the quality characteristics of the measured water.
It has a long service life, stable and reliable performance, easy installation and maintenance, and simple reading.
The JKLC-100 series ultrasonic open channel flow meters also have a variety of built-in algorithms suitable for multiple standard water weirs, with high accuracy.
Optional communication interfaces or printing interfaces are available for easy connection with other DCS systems to realize remote industrial monitoring and control.
The ultrasonic open channel flow meter can also be used as a non-contact liquid level meter to continuously monitor the flow of sewage in open channels and accumulate the flow. It is suitable for flow measurement under open channel conditions in water conservancy, hydropower, environmental protection, and other industrial and agricultural fields.
