Gaseous medium e.g. bio gas, filling level measuring device, has compensation container arranged on plastic sheet during maximum filling, and pressure sensor connected at tube end, where sensor is provided on reference point level

摘要

The device has a compensation container (3) provided at a measuring head. An end of a tube (4) is connected to the head, where the tube is filled with a liquid medium. A pressure sensor (5) is connected to another end of the tube, and is provided on level of a reference point. The compensation container is arranged in a highest position on a plastic sheet (2) during maximum filling. An evaluation circuit is provided for generating an electrical signal that is proportional to volume or level of the gaseous medium.
