Thermal insulation
For optimum temperature and methane fraction measurement (order characteristic for
"Sensor version", option 2 "Volume flow + Biogas analysis"), make sure that heat is neither
lost nor applied to the sensor. Thermal insulation can ensure that such heat transfer does
not take place.
Thermal insulation is particularly recommended in situations where there is a large
difference between the process temperature and the ambient temperature. This can result
in heat convection errors during temperature measurement. A further factor which can
lead to measurement errors due to heat convection is a low flow velocity.
6.2 Mounting the measuring device
6.2.1 Required tools
For transmitter
• For turning the transmitter housing: Open-ended wrench8 mm
• For opening the securing clamps: Allen key3 mm
For sensor
For flanges and other process connections: Corresponding mounting tools
6.2.2 Preparing the measuring device
1. Remove all remaining transport packaging.
2. Remove any protective covers or protective caps present from the sensor.
3. Remove stick-on label on the electronics compartment cover.
6.2.3 Mounting the measuring device
WARNING
L
Danger due to improper process sealing!
‣
Ensure that the inside diameters of the gaskets are greater than or equal to that of the
process connections and piping.
‣
Ensure that the gaskets are clean and undamaged.
‣
Install the gaskets correctly.
1. Ensure that the direction of the arrow on the sensor matches the flow direction of
the medium.
2. Install the measuring device or turn the transmitter housing so that the cable entries
do not point upwards.

6.2.4 Turning the transmitter housing
To provide easier access to the connection compartment or display module, the transmitter
housing can be turned.
