Level Monitoring

See the level. Plan the next step.

Specify level measurement for tanks and reservoirs, with sensing technology selected around the vessel, liquid and installation conditions.

LexaLoop Level — Ultrasonic level sensor — LexaLoop Level

Monitoring scope

Liquid level
High / low limits
Level trends

Relay actions, high/low limits and trend history depend on the agreed controller configuration. Pump control and overflow protection are separately engineered.

Match the vessel

Consider depth, mounting position, foam, condensation and obstructions when choosing the sensor.

Separate level from volume

A level reading can support volume estimation only when vessel geometry and conversion are configured.

Set useful operating limits

Agree high and low levels with the operator and verify the final monitoring configuration.

Non-contact ultrasonic sensor

LexaLoop Level + a configured controller

LexaLoop Level measures the liquid surface without immersion. Choose the range and mounting position, allow for the 0.5 m blind zone, and verify the 4–20 mA connection to the monitoring controller. WaterQ Pro is an option for combined water-quality and level monitoring.

Non-contact level sensing

LexaLoop Level

Ultrasonic level sensor

Measure the liquid surface from above the tank, with a local LCD and an analog output for the monitoring controller.

Measurement: Non-contact ultrasonic
Range options: 0–10 m or 0–20 m
Blind zone: 0.5 m
Output: 4–20 mA and two relays
Display: Built-in LCD for level or distance
Operating temperature: −20 to 60 °C

Allow for the 0.5 m blind zone and check foam, condensation, obstructions and mounting. Controller compatibility and relay functions are confirmed for the final configuration.
