Water level controller

Customized Solutions from Siemens. Water Treatment Processes. How do you control toilet water level? What is water level controller?

When the water level in the over head tank exceeds the required level , the pump automatically turns off and stops the pumping process thus preventing the over flow of water.

It uses a relay to cut off the power supply to the water pump. These automatic water level controllers are used to automatically fill the over-head tank when it starts or has become empty as well as monitor the water level in it. This is a circuit for water level controller is based on transistors and relays. The circuit automatically switches on the pump when water is low in the tank and switches the pump off when water reaches a predetermined mark.

Design a simple water controller in which electrodes are required to sense high and low water levels in a tank. Whenever the water level falls below the low level electrode, the water pump starts and it stops once the water level touches the high level electrode. There is a third electrode which is used to detect the water level from the pump suction port tank.

The first schematic shows how to adapt the water level control to bigger pumps still rated at 120Vac.

This is a SPDT (Single Pole Double Throw) relay, which means it has only two sets of contacts and three terminals for one line only. Solid state electronic water level controls and sensors. We provide the most precise and reliable controllers in the industry. Our automatic microprocessor liquid level controllers are modular, low cost, easy to install, and built to last. The water level is sensed by two floats to operate the switches for controlling the pump motor.

Each sensors float is suspended from above using an aluminium rod. This arrangement is encased in a PVC pipe and fixed vertically on the inside wall of the water tank. Automatic water - level controller circuit.

Such sensors are more reliable than induction-type sensors. Sensor senses the minimum water level , while sensor senses the maximum water level (see the figure). Cooling tower operators and others understand the benefits of a reliable automatic water level control system. So current through Rand Dto trigger base of Q cause Qconducts current cause the transistor Qalso works.

When Qconducts current, LEDwill get a direct bias so glow, and relay-RYwill pull in to contact continuously a water pump with the AC-line 2volts until water to low level (L). Use of this product saves water , saves electricity and save times. Helps in preventing overflow of water from the overhead tank.
