16.9 Process
Sensor
0 to +80 °C (+32 to +176 °F)
An overview of the pressure-temperature ratings for the process connections is
provided in the "Technical Information" document
Select the nominal diameter by optimizing between the required flow range and
permissible pressure loss.
For an overview of the measuring range full scale values, see the "Measuring range"
section →  130
• The minimum recommended full scale value is approx. 1/20 of the maximum full scale
value.
• In most applications, 10 to 50 % of the maximum full scale value can be considered
ideal.
There is no pressure loss.
Sensor
Max. 10 bar (145 psi)
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.
