optionally ±0.1 %
– Minimum temperature effects
• End-to-end modularity for differential pressure,
hydrostatics and pressure (Deltabar M –
Deltapilot M – Cerabar M), e.g.
– replaceable display
– universal electronics
• Easy commissioning without the need for an operating
tool
• Easy and safe menu-guided operation
– on-site via display module
– via 4 to 20 mA with HART

Deltapilot M hydrostatic level measurement and measuring principle
1 Rear isolating membrane of the CONTITE™ measuring cell
2 Measuring element
3 Process isolating diaphragm
g Gravitational acceleration
h Level height
p ges Total pressure = hydrostatic pressure + atmospheric pressure
patm Atmospheric pressure
p hydr. Hydrostatic pressure
p mess Measured pressure in the measuring cell = hydrostatic pressure
ρDensity 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.
Two temperature sensors, which measure the distribution of temperature in the cell, are arranged between the
process isolating diaphragm and measuring element. The electronics can compensate any measuring errors
resulting from fluctuations in temperature with these measured temperature values.
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
tanks, and vessels with a conical outlet.

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.
P01-FMB5xxxx-15-xx-xx-xx-005
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 Signal processing unit determines the difference in pressure and uses this to calculate the level
Note!
• When selecting the Deltapilot M probes, make sure you select measuring ranges that are sufficiently wide
(→see example).
• The process isolating 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 no more than 1:6.
Example:
• Max. hydrostatic pressure = 0.6 bar (9 psi)
• Max. top pressure (probe 2) = 0.3 bar (4.5 psi)
• Max. total pressure, measured with probe 1 = 0.3 bar (4..5 psi) + 0.6 bar (9 psi) = 0.9 bar (13.5 psi)
Measuring cell to be selected: 0 to 1.2 bar (0 to 18 psi)
• Max. pressure, measured with probe 2: 0.3 bar (4.5 psi)
Measuring cell to be selected: 0 to 0.4 bar (0 to 6 psi)
Density measurement You can measure the density in tanks with pressure overlay using two Deltapilot M 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 p1and p2.

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.

P01-FMB5xxxx-14-xx-xx-xx-004
1 Shut-off valves
2 e.g. filter
In the example given, two Deltapilot M devices (each with a gauge pressure sensor) are interconnected. The
pressure difference can thus be measured using two independent Deltapilot M devices.
Caution!
If using intrinsically safe devices, strict compliance with the rules for interconnecting intrinsically safe circuits
as stipulated in IEC60079-14 (proof of intrinsic safety) is mandatory.
System integration The device can be fitted with a tag name and a preset bus address, see →ä53 ff "Ordering information"
feature 895 "Identification:" version "Z1" and "Z2".

2) The MWP (maximum working pressure) for the measuring device depends on the lowest-rated element, with regard to pressure, of the selected components,
i.e. the process connection (→ä30 ff) has to be taken into consideration in addition to the measuring cell (→ see Table above). Pay attention to the pressure-
temperature dependence also. For the appropriate standards and other information, see →ä29, Pressure specifications section.
3) OPL: over pressure limit; depends on the lowest-rated element, with regard to pressure, of the selected components
4) The vacuum resistance applies to the measuring cell at reference conditions.

Resource Block The Resource Block contains all the data that
uniquely identify the device. It is an electronic
version of a nameplate of the device.
1 enhanced
Analog Input
Block 1
Analog Input
Block 2
The AI Block receives the measuring data from the
Sensor Block, (selectable via a channel number) and
makes the data available to other function blocks at
its output. Enhancement: digital outputs for process
alarms, fail safe mode.
2 25 ms enhanced
Digital Input
Block
This block contains the discrete data of the Diagnose
Block (selectable via a channel number 10 to 15) and
provides them for other blocks at the output.
1 20 ms standard
Digital Output
Block
This block converts the discrete input and thus
initiates an action (selectable via a channel number)
in the DP Flow Block or in the im TRD1 Block.
Channel 20 resets the counter for max. pressure
transgressions value and Channel 21 resets the
Totalizer.
1 20 ms standard
PID Block The PID Block serves as a proportional-integral-
derivative controller and is used almost universally
for closed-loop-control in the field including cascade
and feedforward. Input IN can be indicated on the
display. The selection is performed in the Display
Block (DISPLAY_MAIN_LINE_CONTENT).
1 40 ms standard
Arithmetic
Block
This block is designed to permit simple use of popular
measurement math functions. The user does not have
to know how to write equations. The math algorithm
is selected by name, chosen by the user for the
function to be performed.
1 35 ms standard
Input Selector
Block
The Input Selector Block facilitates the selection of up
to four inputs and generates an output based on the
configured action. This block normally receives its
inputs from AI Blocks. The block performs maximum,
minimum, average and ‘first good’ signal selection.
Inputs IN1 to IN4 can be indicated on the display.
The selection is performed in the Display Block
(DISPLAY_MAIN_LINE_1_CONTENT).
1 30 ms standard
Signal
Characterizer
Block
The Signal Characterizer Block has two sections,
each with an output that is a non-linear function of
the respective input. The non-linear function is
generated by a single look-up table with 21 arbitrary
x-y pairs.
1 40 ms standard
Integrator
Block
The Integrator Block integrates a variable as a
function of the time or accumulates the counts from a
Pulse Input Block. The block may be used as a
totalizer that counts up until reset or as a batch
totalizer that has a setpoint, where the integrated or
accumulated value is compared to pre-trip and trip
settings, generating a binary signal when the setpoint
is reached.
