Hazardous areas
Flameproof
Rugged certified enclosure for hazardous process locations, with a clear high-visibility display.
LIV Volumetric Level Indicator
Tank-specific volume and weight indication from any 4-20 mA level transmitter, calibrated at every millimetre.
1 mm resolutionVolume or weightAny tank geometry
Level becomes inventory
A true volumetric reading—not just tank height
LIV converts a transmitter's level signal into the actual quantity stored inside the vessel, even when the tank geometry is non-linear.

Choose the installation that fits your plant
Field installation
Weatherproof
IP65 field display for outdoor and general industrial installations, available in multiple display sizes.
Control panels
DIN-Rail Mounted
Compact panel solution with local display and RS485 Modbus connectivity for control-system integration.
Tank-specific calibration
Accurate across complex vessel shapes
We calculate and preload the volume at every 1 mm of level using your tank dimensions and geometry.
Non-linear geometry
Horizontal Cylindrical Tanks
Precise volume conversion through the curved tank cross-section and dished ends.
Special vessels
Spherical Tanks
Millimetre-level lookup data converts changing cross-sectional area into actual inventory.
Compound profiles
Vertical & Conical Tanks
Handles straight walls, cones and combined vessel sections in one calibrated table.
LIV accepts the 4-20 mA output from radar, capacitance, magnetic, ultrasonic or other level transmitters. Mezur prepares a tank-specific calibration table from the vessel dimensions, with a stored quantity value for every 1 mm of measured level.
