5.1 Mounting requirements
5.1.1 General installation instructions
• Devices with a G 1 1/2 thread:
When screwing the device into the tank, the flat seal has to be positioned on the sealing
surface of the process connection. To avoid additional strain on the process membrane, the
thread should never be sealed with hemp or similar materials.
• Devices with NPT threads:
• Wrap Teflon tape around the thread to seal it.
• Tighten the device at the hexagonal bolt only. Do not turn at the housing.
• Do not overtighten the thread when screwing. Max. tightening torque:
20 to 30 Nm (14.75 to 22.13 lbf ft)
• For the following process connections, a tightening torque of max. 40 Nm (29.50 lbf ft) is
specified:
• Thread ISO228 G1/2 (Order option "GRC" or "GRJ" or "G0J")
• Thread DIN13 M20 x 1.5 (Order option "G7J" or "G8J")
5.1.2 Mounting sensor modules with PVDF thread
LWARNING
Risk of damage to process connection!
Risk of injury!
‣Sensor modules with PVDF thread must be installed with the mounting bracket provided!
LWARNING
Material fatigue from pressure and temperature!
Risk of injury if parts burst! The thread can become lose if exposed to high pressure and
temperature loads.
‣The integrity of the thread must be checked regularly. Also, the thread may need to be re-
tightened with the maximum tightening torque of 7 Nm (5.16 lbf ft). Teflon tape is
recommended for sealing the ½" NPT thread.
5.2 Mounting the device
5.2.1 General installation instructions
NOTICE
Damage to the device!
If a heated device is cooled during a cleaning process (e.g. by cold water), a vacuum develops
for a short time and, as a result, moisture can enter the sensor via the pressure compensation
(1).
‣Mount the device as follows.

• Keep the pressure compensation and GORE-TEX® filter (1) free from contamination.
• Do not clean or touch process membranes with hard or pointed objects.
• The process membrane in the rod and cable version is protected against mechanical damage
by a plastic cap.
• The device must be installed as follows in order to comply with the cleanability
requirements of the ASME-BPE (Part SD Cleanability):

5.2.2 FMB50
Level measurement
• Always install the device below the lowest measuring point.
• Do not install the device at the following positions:
• in the filling curtain
• in the tank outlet
• in the suction area of a pump
• at a point in the tank which could be affected by pressure pulses from the agitator.
• The calibration and functional test can be carried out more easily if you mount the device
downstream from a shutoff device.
• The Deltapilot M must also be insulated in the case of media that can harden when cold.
Pressure measurement in gases
Mount the Deltapilot M with the shutoff device above the tapping point so that any
condensate can flow into the process.
Pressure measurement in vapors
• Mount the Deltapilot M with the siphon above the tapping point.
• Fill the siphon with liquid before commissioning. The siphon reduces the temperature to
almost ambient temperature.
Pressure measurement in liquids
Mount the Deltapilot M with the shutoff device below or at the same level as the tapping
point.

5.2.3 FMB51/FMB52/FMB53
• When mounting 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 resulting from lateral
movement, mount the probe in a guide tube (preferably made of plastic) or secure it with a
clamping fixture.
• In the case of devices for hazardous areas, comply strictly with the safety instructions when
the housing cover is open.
• The length of the extension cable or the probe rod is based on the planned level zero point.
The height of the protective cap must be taken into consideration when designing the
layout of the measuring point. The level zero point (E) corresponds to the position of the
process isolating diaphragm.
Level zero point = E; top of the probe = L.

Mounting the suspension clamp:
1. Mount the suspension clamp (item 2). When selecting the place to fix the unit, take the
weight of the extension cable (item 1) and the device into account.
2. Raise the clamping jaws (item 3). Position the extension cable (item 1) between the
clamping jaws as illustrated in Figure.
3. Hold the extension cable in position (item 1) and push the clamping jaws (item 3) back
down. Tap the clamping jaws gently from above to fix them in place.
5.2.5 Supplementary installation instructions
Seal the probe housing
• No moisture may enter the housing when installing or operating the device, or when
establishing the electrical connection.
• Always firmly tighten the housing cover and the cable entries.

5.2.6 Seal for flange mounting
NOTICE
Incorrect measurement results.
The seal is not allowed to press against the process membrane as this could affect the
measurement result.
‣Ensure that the seal is not touching the process membrane.
5.2.7 Closing the housing covers
NOTICE
Devices with EPDM cover seal - leaking transmitter!
Mineral-, animal- or plant-based lubricants cause the EPDM cover seal to swell and the
transmitter to leak as a result.
‣It is not necessary to grease the thread due to the coating applied to the thread at the
factory.
NOTICE
The housing cover can no longer be closed.
Damaged thread!
‣When closing the housing covers make sure that the threads on the covers and the housing
are free from dirt, such as sand. If you encounter resistance when closing the covers, then
check the threads again for dirt or fouling.
6 Electrical connection
6.1 Connecting requirements
6.1.1 Shielding/potential equalization
• You achieve optimum shielding against disturbances if the shielding is connected on both
sides (in the cabinet and on the device). If potential equalization currents are expected in
the plant, only ground shielding on one side, preferably at the transmitter.
• When using in hazardous areas, you must observe the applicable regulations.
Separate Ex documentation with additional technical data and instructions is included with
all Ex systems as standard. Connect all devices to the local potential equalization.

measuring mode (Deltapilot) as standard.
• The pressure applied must be within the nominal pressure limits of the sensor. See
information on the nameplate.
Perform position adjustment:
1. Pressure is present at the device.
2. Press key for at least 3 seconds.
3. If the LED on the electronic insert lights up briefly, the pressure applied has been
accepted for position adjustment. If the LED does not light up, the pressure applied was

7.2 Operation with device display (optional)
A 4-line liquid crystal display (LCD) is used for display and operation. The local display shows
measured values, dialog texts, fault messages and notice messages. For easy operation the
display can be taken out of the housing (see figure steps 1 to 3). It is connected to the device
via a cable that is 90 mm (3.54 in) long. The display of the device can be turned in 90° stages
(see figure steps 4 to 6). Depending on the installation position of the device, this makes it
easy to operate the device and read the measured values.
