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.
