There are two mode of operation. Sump mode and Bore well mode. When there is a Water in the sump the system works on sump Mode, when the Water in the sump tank gets   Below foot Valve Level  it Automatically switch over to the Bore well Mode. If the water gets filled in the sump tank the system Resumes back to Sump Mode.

This system is suitable for Residences, Commercial complexes, Residential Apartments, hotels, hospitals, Industries, hostels, …Etc..

The system can be upgraded into "Multi-tank control system" to maintain water level in several overhead tanks.

Visual Indications :

Four stage water level indicator for over head tank, water flow indication(Running Line), voltage level indication, power on indication and auto/manual indication.

Features: Switch on the panel if water tank is in required mode and switch off the panel at tank full.
This is a product mainly focused to help people with submersible pumps who previously had little control over the functionality of the pump and had to start manually and stop the pump with all those uneasy methods. which make the operation of these pump difficult for novice users, keeping in mind the ease of use we developed this system which makes the operation of these pumps a child's play.
It is an unique device for single phase submersible pumps.

Low AC Voltage sensing circuit to avoid polarization of electrodes in water. These special stainless steel plastic molded conductive electrodes are Long life sensors and do not require frequent cleaning or replacement.

How It Works : Automatically starts the motor when the water level in the over head tank drops below a pre-defined level (normally 50%) and switches off the motor at tank full or the sump water level drops below foot valve level.

Dry Run
Due to faulty foot valve or air leakage in the pipe if the motor runs dry then it gets switched off automatically and gives fault indication. For more details please watch video demo.  

Voltage Cut-off
Automatic Water Level Controller ULDX-DR-1ph automatically switches-off the pump if the supply voltage drops below 160V or Crosses 250V.
