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 1mm.open channel flow rate changed with it. Measurement accurancy higher , flow measurement more accurante .
