About This Product

This is an electromagnetic flow sensor for drug flow that can measure even pulsating flow. Supports measurement of sodium hypochlorite, caustic soda, etc. This flow sensor is suitable for monitoring the injection of coagulants and sterilizers at water treatment plants and distribution reservoirs.

■Features

・There are no moving parts in the measurement unit, so there is no need to worry about malfunctions caused by foreign objects. ・Realizes pulsation measurement of diaphragm type electromagnetic metering pump ・Supports measurement of sodium hypochlorite and caustic soda ・Products compliant with the positive list system

■Eliminate the air chamber to make equipment more compact

You can directly measure the pulsating flow rate of an electromagnetic diaphragm metering pump. There is no need to eliminate pulsation with an air chamber.

■For gas lock detection of sodium hypochlorite

Gas lock can be detected by simultaneously monitoring the operating signal and flow rate signal of the electromagnetic diaphragm metering pump. *Gas lock is a condition in which air accumulates in the diaphragm room of an electromagnetic diaphragm metering pump, preventing fluids such as sodium hypochlorite from being discharged.

■For grasping injection amount and controlling pH

It is possible to measure and control the injection amount of sodium hypochlorite and caustic soda chemicals used in water treatment plants.

■Applications

・For sterilization processing systems ・For factory wastewater treatment ・For controlling the amount of caustic soda used
