Water Tank Monitoring

Know what’s happening inside your tanks.

Build a tank-monitoring configuration around water quality, stored-water level and the needs of your building’s supply system.

Discuss this solution Device configuration

Treated-water and storage room with a Lexaloop WaterQ Basic analyzer digitally added to the wall beside the filters — WaterQ Basic LL-WQX-100

Monitoring scope

Water quality
Tank level¹
Low / high level¹

¹ Level measurement and high/low indications require an external level sensor and the agreed controller configuration.

Understand stored-water quality

Position the quality sampling point to represent the tank or supply line being monitored.

Add a view of available water

Specify level sensing to suit the tank depth, roof access and internal obstructions.

Design for each tank

Document each vessel, its measurement points and the actions operators need to take.

Quality and level sensor options

WaterQ analyzers + LexaLoop Level

Choose WaterQ Basic or Pro for water quality, and LexaLoop Level for non-contact tank-level measurement. Select the sensor range and mounting around the tank; confirm signal compatibility before combining readings in the monitoring controller.

Expandable water-quality monitoring

Lexaloop WaterQ Pro

LL-WQX-200

An expandable analyzer for water quality, with support for external flow, level and pressure inputs.

Display: 10-inch color touchscreen
Connectivity: 4G; RS485 / Modbus
External sensor inputs: Flow, level and pressure
Dimensions: 500 × 800 × 205 mm
Housing: 304 stainless steel
Power: 100–240 V AC, 50/60 Hz

Pressure and level require separate compatible sensors. Optional measurement channels, interface compatibility and accessories must be specified for the project.

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.
