1Sample at the source
Choose a representative point in the water system. Plan the sample feed, drain and service access before installation.
2Bring readings together
The analyzer brings the selected measurements to its local touchscreen. Probe selection and calibration follow the agreed configuration.
3Connect the next step
Use the specified 4G or RS485 / Modbus connection to bring readings into the agreed monitoring setup.

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

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.
Discuss this sensorDesigned around
your operation.
A useful monitoring setup begins with the conditions on site.
- Define the measurement
Identify the water system, parameters and decisions the readings need to support.
- Match the equipment
Select the probes, controller, mounting, sample handling and communications.
- Agree the delivery
Confirm the installation, integration and operating responsibilities before deployment.
