Electronic Liquid Level Controller

These electronic liquid level controllers are used to indicate or regulate liquid level in various refrigeration applications. These controllers are typically installed on a vessel's liquid level column. They can control the liquid level by controlling a liquid fill solenoid valve. Often they are used to provide high level cut out or alarm. In addition, they can be used to turn off a recirculating liquid pump if a low level occurs. Each unit consists of a float chamber and an electronic controller. The electronic controller has a bar graph display module installed to continously display the rising and falling of the liquid level inside the float chamber.
