 Typical applications: 
 One kind of non-contact open channel flow monitoring instrument for liquid flow measurement and control, including: water, rainwater, wastewater and activated sludge. 

 Features and Benefits 
 Built-in large weir and tank specifications database, such as: V-shaped weir, a rectangular weir, a rectangular slot, round-bottomed groove, Parshall ducts; 
 For non-standard open channel structure, users can enter their own flow curve. 
 Pulse reflection technique 
 Automatic temperature compensation 
 No routine maintenance 
 Non-contact measurement in a relatively hostile environment applications. 

 Principle of operation: 
 U53-type detector works by ultrasonic echo technique, by measuring the flow tank (weir) level height, and then get inside the instrument's microprocessor operations flow. Ultrasonic sensors in the computer control, the transmitting and receiving ultrasound to calculate the liquid level; flow according to the provisions of the formula: can be obtained by liquid flow.
