Application & Construction The level measurement is carried out using a differential pressure transmitter, enabling the compensation for static pressure or vacuum in the tank. The value processed is just the hydrostatic pressurte of the medium measured at the level of the lower diaphragm connected to “H” side of the instrument. This pressure is the sum of the hydrostatic pressure of the liquid and the vapour pressure phases of the medium. In most practical applications the density of the vapour phase of the medium is negligibly small and therefore the measured hydrostatic pressure relates only...

1. Installation of the instrument on pressurised tank Example of configuration via Hand Held Communicator To convert a rise in the level of liquid with density 0.87 from 0 to 3200 mm heigh to a current change from 4 to 20 mA. 1. A) Install the transmitter in working position, place the seal at the appropriate height (tank empty). B) Calculate the width of the measurement range in mmH2O (4°C): 3200 mm × 0.87 g/cm = 2784 mmH2O. C) Using the communicator, set the transmitter to use the units mmH2O at 4°C. D) To determine the start of the measurement range, read off via the communicator the hydrostatic...
