Abstract

1429931 Liquid level indication EAST BRISTOL ENGS Ltd 8 May 1973 [9 May 1972] 21582/72 Addition to 1379554 Heading G1H In an improvement or modification of liquid level measuring or indicating apparatus of the Specification 1379554 a sensing element 20, fitted inside or outside of a tank, has two diaphragms 40, 50 or 340, 350 bounding a gas-filled space/s 31 or 310a, 310b and the diaphragms are respectively coupled on inlet valve 35 or 335 and an exhaust valve 36 or 336 which control the supply and exhaust to the gas-filled space/s 31 or 310a, 310b and the arrangement is such that the diaphragms 40, 50 or 340, 350 form part of a liquid filled chamber 5 or 500 which only communicates with the liquid the level of which is to be measured.
