Ultrasonic open channel Flow Meter ③ Split-type ultrasonic open channel Flow Meter, without calibration rod
Split-type ultrasonic open-channel flow meters work with Parshall flumes, triangular weirs, and rectangular weirs to measure water flow in channels. They are suitable for liquid measurement and are mainly used for measuring flow at sewage treatment plants, discharge outlets of enterprises and institutions, urban sewers, and irrigation canals in farmland water conservancy projects.

2. Product Advantages
From the power supply section, the circuit design uses high-quality power modules, and components are selected from imported, highly stable and reliable devices, making it fully comparable to similar instruments worldwide.
● The patented acoustic intelligent technology software performs intelligent echo analysis without any debugging or other special steps. This technology features dynamic thinking and dynamic analysis.
● The patented acoustic intelligent technology greatly improves meter accuracy, with liquid level accuracy reaching 0.3%, and can resist multiple interference waves.
● This instrument is non-contact and does not come into direct contact with the liquid, resulting in a low failure rate. The instrument offers multiple installation methods; users can calibrate the instrument entirely according to this manual.
● All input and output lines of the instrument are protected against lightning and short circuit.
