·The ULFM PRO ultrasonic open channel flowmeter adopts a 5-inch touch screen for more intuitive operation, adding personalized functions such as historical recording, real-time curves, and data export, and supporting multiple languages for more internationalization. 80G/120G FMCW radar level transmitter can also be connected as a radar open channel flow meter for higher accuracy.
·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.
·Enhanced liquid level correction function, with higher detection accuracy and more 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 weirs and grooves: support various weirs and grooves in both national and ISO versions: Basher weir, 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 multiple 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.
