·Non contact measurement, ultrasonic probe does not come into contact with the measured medium, has no risk of wear, corrosion, etc., has a longer service life, and is easy to maintain.
·High detection accuracy and accurate flow measurement. The flow rate of the open channel is detected with an accuracy of 1mm as the liquid level changes. The flow rate of the open channel changes with every 1mm change in the liquid level.
·Adapt to various weir grooves: support various weir grooves in both national and ISO versions: Basher groove, triangular weir, rectangular weir (customizable width), and can input custom flow relationship formulas.
·Large screen with backlight graphic LCD display, optional menu system in Chinese/English.
·The flow unit can be set, the cumulative flow can be adjusted, and there are various practical custom settings.
·The open channel flow host has powerful functions and can provide up to 6 relay switch signals. It can accumulate pulse output of flow and provide MODBUS-RTU digital signals.
·Customizable solar power supply and wireless transmission functions.
