Surge Tanks

Additional Details

The surge tank will be fitted with level switches and instrumentation to enable level detection and control actions to be
taken.

Typically control actions will be taken at liquid High Level, Low Level and Normal positions and there will be two alarm positions, one at High Level Alarm and one at Low Level Alarm.

levelgaugeassemblyThe most common arrangement is known as Five Point control and is ideally suited to surge applications where the pumping condition does not vary significantly or where there is a fixed speed pump.

Typically a bypass level gauge will be fitted to the tank to which magnetically operated switches will be attached, these switches will be operated by a magnetic float within the level guage.

In cold environments the level will require insulation to prevent freezing of the water inside.

Additionally the surge tank will be provided with a solenoid activated valve which is arranged to release air from the vessel should the level detection instrumetation show that the liquid level has fallen below the normal level.
