Page 26: Commissioning Of Level Measurement
Pressure Transmitter LHCR-51, LHCS-51 Commissioning Commissioning of level measurement 5.4.1 Information on level measurement NOTICE You have a choice of two methods for calculating the level: "In pressure" and "In height". The table in the "Overview of level measurement" section that follows provides you with an overview of these two measuring tasks. - Page 27 Pressure Transmitter LHCR-51, LHCS-51 Commissioning 5.4.3 Level selection "in pressure" Calibration with reference pressure (wet calibration) Example: In this example, the level in a tank should be measured in "m". The maximum level is 3 m (9.8 ft). The pressure range is set to 0 mbar to 300 mbar (4.5 psi).
