Measured pressure in the measuring cell = hydrostatic pressure

ρ Density of fluid

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 S. In contrast to conventional gauge pressure sensors, the precision measuring element (2) in the
CONTITE™ measuring cell is absolutely protected between the process diaphragm (3) and the measuring
diaphragm (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 diaphragm to the measuring element by means of an oil without any loss in pressure.
Two temperature sensors are arranged between the process diaphragm and measuring element which measure
the distribution of temperature in the cell. The electronics can compensate any measuring errors resulting from
fluctuations in temperature with these temperature measured values.

Level measurement in closed tanks with pressure overlay

You can determine the differential pressure in tanks with pressure overlay using two Deltapilot S probes. 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.

P01-DB5xxxxx-15-xx-xx-xx-007

Level measurement in a closed tank with pressure overlay

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

Note!

• When selecting the Deltapilot S probes, make sure you select large enough measuring ranges
(→ see example).

• The measuring diaphragm of probe 2 must not be flooded. This generates additional hydrostatic pressure
which distorts the measurement.

• The ratio of hydrostatic pressure to top pressure should be max. 1:6.

Example:

• Max. hydrostatic pressure = 600 mbar

• Max. top pressure (probe 2) = 300 mbar

• Max. total pressure, measured with probe 1 = 300 mbar + 600 mbar = 900 mbar
⇒ Measuring cell to be selected: 0 to 1200 mbar

• Max. pressure, measured with probe 2: 300 mbar
⇒ Measuring cell to be selected: 0 to 400 mbar

Density measurement

You can measure the density in tanks with pressure overlay using two Deltapilot S probes and a signal
processing unit or a PLC. The signal processing unit or the PLC calculates the density from the known distance
Δh between the two probes and the two measured values p

and p2.

Level measurement with automatic density correction (with changing media 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 S probe currently
measured and the known distance between Deltapilot S and the limit switch. The signal processing unit then
calculates the level from the new density and the measured pressure from the Deltapilot S probe.

Measuring system Measuring system with 0.2 to 1.2 mA analog – FEB11(P)

The electronic insert returns a current signal of 0.2 to 1.2 mA that is in proportion to the pressure. The
FMC420 silometer provides voltage to the electronic insert and evaluates the current signal that is in proportion
to the level. The standardized signals of 0 to 10 V and 4 to 20 mA (0 to 20 mA) are then available at the output
of the silometer. → See also Technical Information TI077F and Operating Instructions BA179F.

Measuring system with PFM – FEB17(P)

The electronic insert returns a pulse-frequency-modulated signal of 200 to 1200 Hz. The evaluation and
operating unit Prolevel FMB662 provides power to the electronic insert and converts the PFM signal of the
probe to a standardized current or voltage signal. → See also Technical Information TI234F and Operating
Instructions BA144F.

Measuring system with 4 to 20 mA HART – FEB22(P)

HART is a field-tested industry standard accepted worldwide. In HART technology, the 4 to 20 mA analog
transmission and the digital communication take place simultaneously via the same wire pair. The 4 to 20 mA
analog signal is used for rapid measured value transmission. The digital HART signal allows device data to be
read and written, e.g. for diagnosis and maintenance information.

Measuring system with PROFIBUS PA – FEB24(P)

PROFIBUS PA is an open fieldbus standard. It allows multiple sensors and actuators to be connected, even in
Ex-areas. By means of PROFIBUS PA, energy is supplied to the devices with two-wire technology and the

Operating conditions (installation)

Installation instructions for
compact version DB50,
DB50A, DB50L, DB50S

• Always install the device under the lowest measuring point.

• Do not install the device at the following positions:
In the filling curtain, in the tank outlet or at a point in the tank that can be reached by pressure pulses from
the agitator.

• The calibration and functional test can be carried out more easily if you mount the device after a shut-off
device.

• Deltapilot S must be included in the insulation for media that can harden when cold. The use of rod or cable
versions is also possible.

Installation instructions for
rod and cable versions
DB51(A), DB52(A) and
DB53(A)

• When mounting the rod and cable versions, make sure that the probe head is located at a point as free as
possible from flow. To protect the probe from impact from lateral movement, mount the probe in a guide
tube (preferably made of plastic) or secure it with a clamping fixture. For devices for Ex-areas, see Safety
Instructions (XAs).

• The length of the extension cable or the probe rod is based on the planned level zero point. The top of the
probe should be at least 5 cm under this.

Supplementary installation
instructions

Process diaphragm

• Do not use sharp or hard objects to handle or clean the process diaphragm. Build-up has no effect on the
measurement result as long it is porous and does not present a mechanical load on the diaphragm of the
pressure measuring cell.

• The process diaphragm on all Detapilot S rod and cable extension is protected against mechanical damage
by means of a plastic cover.

Seal

• Deltapilot S with G 1 1/2 thread:
When screwing the device into the tank, the flat seal supplied must be placed on the sealing surface of the
process connection.

• Deltapilot S with NPT thread:
– Wrap and seal the thread with Teflon tape.
– Tighten the device at the hexagon head only. Do not turn the device by the housing.
– Do not screw in the thread too tightly. Max. torque: 20...30 Nm

Sealing the probe housing

It is important that no moisture enters the housing while mounting the probe, connecting the electronic insert
and operating the measuring system.

• Always screw the housing cover and the cables entries tight.

• The O-Ring seal in the housing cover and the thread of the aluminum cover are lubricated. If this lubrication
has been removed, replace it with silicone grease or graphite paste, for example, so that the cover seals tight.
Do not use mineral-oil based greases. These can destroy the O-ring.
