Monitoring Devices
Liquid Level Controller/ Water Level Controller
Overview
Liquid Level Controller Relay
A Liquid Level Monitoring Relay (LLMR) is a control and protection device designed to monitor and regulate liquid levels in tanks, reservoirs, and pipelines. It detects high, low, or intermediate liquid levels and triggers pumps, alarms, or valves to maintain safe and efficient operation. These relays are essential in water treatment plants, pumping stations, industrial process systems, and HVAC applications, ensuring reliable automation of liquid handling processes.
Accurately monitors high and low liquid levels, ensuring pumps and valves operate only when needed.
Protects pumps from running without liquid and prevents tank overflow, reducing equipment damage and water wastage.
Simple wiring, DIN-rail mounting, and adjustable sensitivity make installation and commissioning quick.
Benefits
- Fully Automatic operation enabling both draining and filling simultaneously with a single device
- Adjustable sensitivity level from 1k to 200k Ohm
- Includes provision for Manual start
- Protects submersible pumps against dry running and prevents overfilling
- Enables maximum utilization of incoming liquid (eg. water) supply
- Specially designed corrosion and shock resistant sensors to ensure trouble free operation.
