Stable Control of Water Supply and Drainage for Water Tanks

Stable reading of rapid input changes, such as surface waves in water tanks

ON/OFF control of water-supply and drainage pumps is performed by measuring the water level in the tank using an ultrasonic displacement sensor. Fluctuations in the present value caused by surface waves can be smoothed by using the input digital filter to stabilize control.

Know-How

Stable water tank supply and drainage are performed by using the input digital filter function of the E5CN Temperature Controller.

Benefit / Efficiency

Control can be performed with stable water tank supply and drainage.
