5. Assembly
5.1 General
Before assembly all parts have to be checked for particles of packing material.
The flow meter TR3 possesses G1 external threads on both sides which allow it to be installed in any
pipe. When doing so, please ensure that the meter is not under mechanical stress due to tension/
pressure or bending. To avoid this, an elastic equalizing element is to be used, and the lines are to be
supported in a suitable manner. In order to prevent damage, the tightening torque at the G1 external
threads are not to exceed 30 Nm.
The flow direction can be chosen freely.
We recommend the use of front-side flat seals or O-rings at the ends of the screw threads for sealing
purposes.
After being screwed into the pipe, the electronic housing can be rotated freely around the measuring
chamber. This allows the display to be brought into a position that is comfortable for the user.
The pressure surges that occur in the pipe are not to exceed the nominal pressure.
5.2 Assembly with drum pump connection G1
1. Screw the drum pump connector G1 (1) at the inlet of the flow meter (
→
Fig. 2).
Now commercially available hose connectors G 1 can be connected at the outlet of the flow meter.
