Hawker Electronics - Conductivity Level Control Applications
Below are some simple diagrams to show the potential uses of Conductivity Level controls
|
|
Control of 1 pump and 1 high level alarm at levels fixed by electrode lengths using dual controller type AC3/LH |
|
|
|
|
Control of 2 pumps/valves between 2 levels fixed by electrode lengths. With facility to change the starting order every cycle |
|

|
|
Control of 1 pump/valve between 2 levels fixed by electrode length. This unit is c/w motor starter unit, type AC Plus |
|

|
Borehole pump controlled from electrodes in break tankBorehole pump controlled from electrodes in break tank. Low level protection for borehole pump from electrodes suspended in borehole, stopping on lower electrode and starting when water level recovers to higher level |
|

|
|
Arrangement when break tank is remoteControl of 2 levels in borehole fixed by suspended borehole electrode. Pump controlled by level in Remote break tank.Borehole pump stops on high pressure restarts when ball valve re-opens after suitable time delay. Time clocks can be incorporated in these systems to limit pump running to low tariffs. |

Indication of water level in borehole using pressure transducerCan be incorporated in above systems |
