Examples of applicationsSubmersible pumpsSQE-NEMaintaining a constant water tableFunctioning and benefitsThe water table can be maintained at a constant levelby adjusting the pump performance. For example,maintaining a constant water table is useful when thegroundwater should be kept out of a building site orwhen salt water should be kept from penetrating aborehole containing potable water.The example shows how to maintain a constant watertable by adjusting the pump performance. At low or noflow and thereby low performance, the flowmeterensures that the pump stops in order to avoidoverheating of the motor.SensorsLevel Description ReactionLevel sensor (pos. 11)Warning (max.)Desired levelWarning (min.)Too high water level.Possible cause:Insufficient pump capacity.The water level that shouldbe maintained.Too low water level.Possible cause:Too high pump capacity.Alarm relayoperates.Alarm relayoperates.5R10021 291 SQE-NE pump2 Cable3 Cable clips5 CU 300 control unit11 Level sensor21 Mains connection, 1 x 200-240 V, 50/60 Hz22 Riser pipe29 R100 remote control30 Straining wire31 Wire clamp3122233031111Warning (max.).Desired levelWarning (min.).Recommendedmin. 0.5 m.min. 0.5 mTM01 2459 4801Fig. 16 Maintaining a constant water tableMaintaining a constant water tablePos.
