Arrangement for measuring the difference in height between two liquid levels

摘要

A differential-pressure sensor (7) with a mechanically coupled displacement transducer is used to measure the difference in height ( DELTA H) between two liquid levels (4, 6), in particular between the upstream water and the downstream water at a device (3) producing a banked-up water level. The two sides of the pressure diaphragm are attached to continuously closed, branchless pressure lines (16, 17), the free end of which is in each case located below one of the two water levels and in which a statically arranged pressure-transmitting medium is exposed at the free ends directly or indirectly to the liquid pressure.
