Operating Instructions
4.
Mounting and installation
4.1 Typical components of the measurement point:
Transmitter in the DIN rail housing or field housing
•
Sensor mount for welding to the pipeline
•
Sensor (union nut, spacer rings, sealing ring for adjusting to the wall thickness)
•
Installation instructions
•
C1- or C3-box
•
4.2 Required equipment
Ø 20 mm-twist drill bit
•
32 mm open-ended spanner for union nut
•
Locking ring pliers (Ø 20 mm) to adjust the sensor to the wall thickness
•
4.3 Sensor installation
Proceed as follows to install the sensor:
Decide on the installation position on the pipe. It should be installed from the top on horizontal or
•
angled pipelines.
Note: Depending on the application, up to 3 sensors can be used on pipeline diameters larger than
•
200 mm, whereby the sensors must be mounted 120 mm apart and offset in relation to each other at an
angle of 120°.
The distances apply to vertical and horizontal installations.
•
Ensure that the measurement point is at an adequate distance from valves, manifolds, blowers and
•
bucket wheel feeders and other measurement ports such as those used for pressure and temperature
sensors, etc. (See Fig. 6)
Fig. 6: Minimum distances of the measurement point from pipe geometries and fittings
On free-fall applications (for example, after screw conveyors or bucket wheel feeders), a drop height of
•
at least 300 mm is ideal.
