Filed: 1991-09-18
Abstract: Appts. for determn. of the fluid level (B) in a container (1), esp. a reactor pressure vessel, by means of a differential pressure gauge (4) mounted above the roof of the container. The latter is connected by means of two pipelines (5,6) leading downwards. One (6) to the gas/steam filled space (3) above the fluid level and the other (5) below it to the liq. filled part (4) of the container. An output unit (7) is connected to the differential pressure gauge (4) to which values for the fluid and gas/steam densities are supplied. The pipelines (5,6) are filled with a fluid of known density, ideally saturated, superheated steam. The pipelines (5,6) are provided with lockable caps (8,9) for insertion of extra gas to avoid any pressure drop. Further they may be heated (using surrounding electric coils, gamma or neutron heating) and have double walls to avoid the formation of condensation inside them.
