A fluid level gage comprises a chamber with two membranes mounted to the walls of the chamber at different heights and connected to each other by means of a flat-topped beam that rotates on axle, differential-transformer transducer the ram of which is rigidly connected to the beam, following system – electric drive and measuring device. The membranes have same effective areas, the arms of the flat-topped beam have different lengths land l(l>l), at the end of the larger arm of the flat-topped beam a console is rigidly installed in vertical position, the ram of differential-transformer transducer and its coil are installed on the console and in the trough-like guide with straight sides, respectively, with possibility of displacement and fixation in given position, and the lengths of the arms of the beam land land the console l, respectively, in direction from down upwards are related with relationship 1:(1.5-2.0):(1-2). |
