Level sensor for liquids MIRA+


Level gauge for liquids MIRA+™ is designed for continuous measurement of level and temperature of liquids in tanks. The level sensor for liquids MIRA +™ is designed for continuous measurement of the level and temperature of various liquids in storage tanks.

Level gauges MIRA+™ can be additionally used for interface level measurement, alarm and notification generation when sub-critical or critical process parameter values are estimated (e.g., for overfilling protection - when level reaches “top fill level” or “alarm level” that was optioned by an operator).

Level sensor has EX protection type “Intrinsically safe electrical circuit” and can be mounted in hazardous areas of classes 0,1,2.

The level gauge is certified and can be used in custody transfer applications.

It is possible to produce equipment upon special requirements of the Customer. Information integration from the level sensor into any automation systems is available to signal subcritical and critical parameter values (e.g. approaching the set upper/lower product level), control interphase level.


Level gauges can be used for custody transfer, process control, continuous monitoring of various tank farms. Sensors are applicable for the use with the following products:

Level gauges for use in oil and gas industry, refineries
MIRA+ level sensors can be used for custody transfer and monitoring of oil products
Level sensors for industrial applications, production facilities, etc.
Level and temperature sensors for use in food applications
Level sensors for use in chemical and petrochemical industries
Level measurement solutions for use in power industry


Level sensor for liquids «MIRA+» meets the requirements:
