Types of Electronic Water Level Controller

There are various types of automatic water level controller that help in maintaining the required level of water in tanks. Each type has its function and setup. Below, the focus is on the different kinds of water-level controllers.

Hydrostatic Pressure Sensors

These sensors assess water level by measuring the pressure induced at a sensor's base due to the water column above. As the level fluctuates, the pressure changes, and the sensor translates these variations into an electrical signal denoting the water level. This technique is favored for deep-water settings due to its accuracy at significant depths.

Capacitive Level Sensors

Apart from water treatment, capacitive sensors find use in food and beverage applications. They operate by mapping the change in capacitance generated by the liquid disrupting the electric field between sensor plates. So with every liquid change, the capacitance alters. This shift allows the precise identification of liquid levels. It is especially useful for insulating materials like oils and alcohols.

Ultrasonic Water Level Controllers

Ultrasonic sensors determine liquid levels by dispatching sound waves from a transducer, which then measures the return time of those waves after bouncing off the liquid surface. The time correlated to the level of the liquid. They function efficiently in diverse kinds of liquids or even slurries, necessitating non-contact measurement.

Float-Based Water Level Controllers

This controller consists of float switches that trigger when a float rises to a particular level, either high or low. The system then either fills or empties the tank. This ancient method, based on buoyancy, remains popular for its simplicity and effectiveness in several applications.

Toroidal Conductivity Sensors

The conductivity of toroidal sensors tagged liquids is used for water level control. These sensors operate without direct contact with the liquid. Because of their design, they resist harsh environmental elements. This makes them viable for managing chemically treated or contaminated liquids. These sensors measure liquid levels by mapping the conductivity variance, guided by the liquid's changing properties.
