Micro controller based Digital Water Level Controller.

Digital Volt and ampere meter are provided to see system voltage and load current accordingly.

Two seperate display for volt and amp.

Over load Protection,

Adjustable overload from 0 to 50 A

Current based dry run protection,

Adjustable dry run current from 0 to 50 A

Dry run Auto Reset timer provided with with bypass facility 

It has current based dry run protection. If motor runs without water then it take lower ampere (current) then actual current. so when motor current down from actual current, it stop the motor and protect motor from dry running.

Automatic Overload and Dry run current adjustable

When motor start, press the start button for 5 seconds, This unit will set overload and dry run current automatically 

High & Low Voltage protection,

Adjustable voltage limit (High and low both voltage protection limit adjustable)

Short circuit protection

protection bypass facility 

Cyclic timer provided with bypass facility (adjusatble from 0 to 999 min) If user want start and stop the motor on perticuler time then user can set the on and off time of cyclic timer

Cyclic timer available in auto mode with water controller and in bypass mode without water level controller 

In auto mode cyclic timer - water level controller work on cyclic on time mode, as per preset time

Delay timer provided with bypass facility (adjusatble from 0 to 999 min)

On delay timer and off delay time provided (adjusatble from 0  to 999 min)

Auto switch provided with bypass facility (When power goes and comes it will start the unit automatically)

Auto switch timer provided (when power goes and comes it will start with preset time,) timer adjustable from 0 to 999 sec.

High accuracy in over load and dry run current

Motor on indication provided 

voltage and amp indication provided

Auto byapass indication provided 

Water level controller and water level indication for overhead and underground tank.

Error messages shows on display 

RESET button provided to reset unit

High quality ABS. enclosure provided.

Set button provided to set the current voltage and timer.

Reset button provided to reset the unit 

Factory reset facility in case of incorrect value entered.

Working :

This model automatically switches ON and OFF the Motor.

When the water level of the overhead tank becomes low means water gets down from the middle sensor and if water is present in the underground tank or sump, the motor gets started automatically. The tank starts filling up. when the water level reaches to the higher level, the motor automatically gets switched off.

AUTO OFF WHEN TANK IS FULL OR SUMP IS EMPTY.

This model has dry run protection so it only starts the motor if water is present in the underground tank or sump.

Sensing element : S.S sensor, it is free from oxidation, long life. Any conducting wire can be used for sensor.

All signals passes in sensors through the AC filter circuit that improves the life of sensor,

Isolated supply provided

Sensor fault detection provided, if sensor got failed LED start blinking

Auto and Manual mode switch available. In auto mode the motor starts and stops automatically. In manual mode the user can start and stop the motor by pressing the start and stop button of the controller. No additional wiring is required to operate the motor manually. 

No sensors are required to detect dry running.

Water Level indication provided for both tank.

No starter is require as it is combination of starter and water level controller.

Fully automatic, controls from underground tank to overhead tank so no man power required. Long service Life.

Electrolysis free design
