Level Control

Liquid level control is a huge market with many different technologies our level controllers are for safe area use designed to provide simple control systems. By using more than one controller we are able to offer control of two or more pumps and high and/or low level alarms.

Our ALC1101controller is designed for inside panel mounting. The principal of operation is by detecting the electrical resistance between electrodes set at desired levels. The electrodes are connected to a low voltage electrical sensing circuit which is amplified to control the switching relay within the liquid level controller. When the liquid rises or falls and makes or breaks contact with an electrode the switching relay energises or deenergises as per the required setting.

The PLS1 pneumatic level switch has a tube which cut to the desired length as the liquid rises it covers the tube and pressurises the air inside which operates a switch in the controller head. The advantage being the solution does not need to be conductive so this is an ideal answer for level control of demin water tanks.

The FS10 is simply a float switch with a 10 meter cable providing a low cost reliable solution to pump control and alarm.
