Automatic Water Level Controller with Cyclic Timer

Automatic water level controller for borewell and openwell pumps. Compare four VUKAR models for single or three phase motors. This page is the model selector; each linked product page covers one exact model and application.

Choose the right water level controller

• DEV-H1 — Single phase borewell, single float switch
• DEV-H2 — Single phase openwell or monoblock, double float switch
• DEV-G1 — Three phase borewell, single float switch
• DEV-G2 — Three phase openwell or monoblock, double float switch

The four selectable models on this page include a cyclic timer. Use the dedicated model pages for the exact phase, pump type, float-switch arrangement and protection details.

How automatic water-level control works

The controller starts the pump when the overhead-tank level falls and stops it when the tank is full. Dry-run protection stops the motor when the water source is unavailable.

Single or double float switch?

• Single float switch: for an overhead-tank application.
• Double float switch: for an overhead tank plus an underground tank or sump.

Monitoring, motor protection and timers

• Dual digital display, motor-on indication and fault display
• Overvoltage, undervoltage, overload and dry-run protection
• Motor run counter and fault counter
• Auto-off timer, power-on auto-start timer and cyclic timer
• Programmable restart after a dry-run stop

Why use a cyclic timer?

A cyclic timer runs and pauses the pump at set intervals. It is useful where a low-yield borewell needs recovery time between pumping cycles.

Installation guide

Installation and protection settings should be completed by a qualified electrician with the supply isolated. For installation, fault-code or warranty help, use the VUKAR contact and technical-support page.
