BED TESTING LIQUID LEVEL INDICATORS Russian patent published in 1997 - IPC

FIELD: testing, certification and calibration of liquid level indicators. SUBSTANCE: proposed bed includes measurement tubes placed vertically and intercommunicating by means of transition members, unit controlling liquid in measurement tubes, pipe-lines to feed and drain liquid, electric motor drive and mechanisms registering positions. Transition members and measurement tubes have same height and are formed by vertical sections of same height telescopically connected and sealed. Each section is coupled to its mechanism registering positions and one of sections is connected to electric motor drive.
