Level sensor for LPG

Overview

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

Scope

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 LPG measurement, use in oil and gas industry, refineries
MIRA+ level sensors for LPG can be used for custody transfer and monitoring of  liquid petroleum gases stored in a reservoirs
Industrial applications of an LPG Level sensors, usage for LPG level measurement for production facilities, etc.
