Measuring ranges*
0 (1) to 100 kg / h or 0 (12) to 1250 Nl / min**
* Reference values are given for applications with air under atmospheric
conditions. The values in brackets indicate the low limit of the measuring
range for which the measured value accuracy indicated is specified.
** You can specify any unit, as long as it can be transformed into a mass or
standard volume flow. (notation also: l / min-qn).
Measured medium temperature

Measuring medium pressure
Standard: 10 × 102 kPa (10 bar abs.)
High-pressure version: 16 × 102 kPa (16 bar abs.)
Influences
Temperature effect
< 0.1 % / K of measured value
Pressure effect
≤ 0.2
% / 100 kPa (/bar) of the measured value
Pressure drop
< 10 kPa (100 mbar) at full scale and using the small flange
adapter DN 25; decreasing
approx. quadratically at smaller flow rates.
Installing the sensor
Before installing the sensor, observe the following points:
• The ambient conditions at the installation site comply
with the requirements in
Ambient conditions
on page 9.
• The operating pressure complies with the requirements
in
Measuring medium pressure
on page 9
• For each measuring system a calibration certificate is
delivered which contains all the key information (such as
serial number, calibrated measuring range, order number,
outputs set in delivery status). It must be checked
whether this data complies with the requirements of the
measuring point.
Install the sensor:
1. Install the sensor with process adapters in the piping.
2. Create the electrical connections in accordance with the
information
Electrical connections
on page 10.
Note
The variable process adapters are fastened in the sensor with a
fine pitch thread. The connection can be cautiously loosened
using a SW 30 open-end wrench.
Before carefully reinserting the process adapters, the threads
should be cleaned and lightly lubricated. Make sure the O-ring is
seated properly.
