Position Term/Abbreviation Explanation

1 OPL The OPL (over pressure limit = sensor overload limit) for the sensors

depends on the lowest-rated element, with regard to pressure, of the selected components, i.e. the process connection must be taken into consideration in addition to the measuring cell. Also observe pressuretemperature dependency. For the relevant standards and additional notes, see the " ä 35" section. The OPL may be applied for a limited time period.

2 MWP The MWP (maximum working pressure) for the sensors depends on the

lowest-rated element, with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional notes, see the " ä 35" section. The MWP may be applied for an unlimited time.

• Calibrated/Adjusted measuring span: 0...5 bar (0...75 psi)

• Lower range value (LRV) = 0 bar

• Upper range value (URV) = 5 bar (75 psi)

In this example, the TD is thus 2:1. This span is based on the zero point.

Density of the medium

Due to its weight, a liquid column creates hydrostatic pressure. If the density is constant, the hydrostatic pressure depends solely on the height h of the liquid column. The CONTITE™ measuring cell, which works on the principle of the gauge pressure sensor, constitutes the core of Deltapilot M. In contrast to conventional gauge pressure sensors, the precision measuring element (2) in the CONTITE™ measuring cell is absolutely protected, situated between the process isolating diaphragm (3) and the rear isolating membrane (1). Thanks to this hermetic sealing of the measuring element, the CONTITE™ measuring cell is absolutely insensitive to condensate/ condensation and aggressive gases. The pressure applied is transferred from the process isolating diaphragm to the measuring element by means of an oil without any loss in pressure. Any measured errors due to fluctuations in temperature are compensated for in the electronics unit by means of the sensor temperature.

A linearization function with max. 32 points, based on a table entered either manually or semi-automatically, can be activated locally or remotely. This function facilitates measurement in engineering units, and provides a linear output signal for spherical and horizontal cylindrical vessels, and vessels with a conical outlet.

NOTICE

Level measurement in closed tanks with pressure overlay

You can determine the differential pressure in tanks with pressure overlay using two Deltapilot M. The pressure measured values of the two probes are sent to a signal processing unit such as Endress+Hauser RMA or a PLC. The signal processing unit or PLC determines the difference in pressure and uses this to calculate the level and the density where necessary.

Level measurement in a closed tank with pressure overlay

1 Deltapilot 1 measures the total pressure (hydrostatic pressure and top pressure) 2 Deltapilot 2 measures the top pressure 3 Signal processing unit determines the difference in pressure and uses this to calculate the level

Measured errors can occur.

Large measured errors can occur if the ratio of the level to the top pressure is >1:6. This does not affect reproducibility. ‣ When selecting the measuring cell, make sure you select measuring ranges that are sufficiently

wide ( see example).

Example:

• Max. hydrostatic pressure = 600 mbar (9 psi)

• Max. top pressure (Deltapilot 2) = 300 mbar (4.5 psi)

• Max. total pressure, measured with Deltapilot 1 = 300 mbar (4.5 psi) + 600 mbar (9 psi) = 900 mbar (13.5 psi) measuring cell to be selected: 0 to 1200 mbar (0 to 18 psi)

• Max. pressure, measured with Deltapilot 2: 300 mbar (4.5 psi) measuring cell to be selected: 0 to 400 mbar (6 psi)

Possibility of probe 2 flooding during differential pressure measurement.

Measured errors can occur. ‣ When installing, make sure that probe 2 cannot be flooded.

A0023544

Level measurement with automatic density correction (with media changing in the tank)

Level measurement with automatic density correction is possible in conjunction with a limit switch such as Liquiphant and a PLC. The limit switch always switches at the same level. In the switch point, the signal processing unit determines the corrected density from the pressure of the Deltapilot M currently measured and the known distance between Deltapilot M and the limit switch. The signal processing unit then calculates the level from the new density and the measured pressure of the Deltapilot M.
