The present invention encompasses an arrangement ("A") determining a liquid level (1) within a container (2) under the utilisation of, a pressure-sensitive and bottom-related sensor unit (3), in order with the aid of a hydraulic and/or pneumatic pressure to permit the evaluation of the height ("H2") of the liquid level above said sensor unit (3), a tube system (4) between the sensor unit (3) and a measurement unit (5), in order to distribute said pressure ("Pa") within the sensor unit (3) to said measurement unit (5) in order there, via circuits and functions (5), to generate a significative indication corresponding to a thus evaluated pressure value. Said sensor unit (3) is structured as an elastic blister or a membrane, for instance a rubber blister (3a), and with connected tube system (4) displays a pre-set pressure ("Pi"), where said pressure may correspond to a pressure value representative of the total container height ("Hl") or another selected pressure value. A pressure value propagated (7, 8) automatically via the measurement unit (5), such as an alarm value (Pmin; Pmax) is to be able to be accompanied by an identification of the transmitting arrangement ("A") |
