FIELD: instrumentation.
SUBSTANCE: proposed device is composed by measuring vessel with cover whereto pressure gage is connected. Bottom is composed of membrane separating measuring vessel from air chamber accommodating nozzle communicated with atmosphere and connected via orifice to feed line. Variable-volume chamber is connected to measuring vessel and accommodating piston and spring communicated with said air chamber and air valve first nozzle, second nozzle of the latter is connected to measuring vessel. Note here that nozzle chamber with first nozzle is communicated directly with atmosphere. Throttle is connected to nozzle chamber with second nozzle, throttle outlet being communicated with atmosphere while control chamber is connected to pneumatic toggle switch.
EFFECT: control automated by simple and cheap means, simplified measurements, higher accuracy of results.
