Product Description
                                          Ultrasonic open channel flow meter

Ultrasonic open channel flow meter is a high accuracy flow instrument which is used the principle of ultrasonic measuring Venturi canal or Parshall flume. It measure the time of reflected back after sound wave contact to channel water , then  according to the formula figure out channel flow, it can provide flow output, display  flow velocity and total flow.

-Water and wastewater treatment: pump house, collecting well, biochemistry reaction tank, settling tank etc.
-Power, mine, grout pool, coal slurry tank, butter storage tank, stock ground or Part of the mobile device control etc.
-The food industry: winery, granary, food material  fill the tank etc control system form a complete set using.

-Open channel flow rate can be measure per 1mm according to the liqild level.
-The liquid level change channel flow rate changed with it. Measurement accurancy higher ,  flow measurement more accurante .
-Suitable for variety of flume:Parshall flume,Right-angled triangle weir,  Rectangular weir 
-Variety of flow unit is optional
-Fully closed structure, Strong anti-corrosion
-Strong anti-interference ability
-Low blind zone,High sensitivity,High stability
-Provide at most 6 relay switch signal
-MODBUS-RTU digital signal is avaliable.
-The distance from transmitter to ultrasonic probe can up to 100m
-AC and DC power supply is optional.
-Romote control setup parameter avaliable,Easy to operate.
