3.2 Installation
3.2.1 Check before Installation
a) The measuring pressure is in the measurement range;
b) The measuring medium is compatible with construction;
c) The measuring medium would not jam the pressure-leading hole.
3.2.2 Installation Method
Usually the transmitter should be mounted vertically up to the horizontal
direction. If the condition is unavailable, the allowed max. mount slope
angle from transmitter to the horizontal direction is 30 degree. It is not
recommended to mount the transmitter invertedly.
Take the pressure port M20×1.5 male with water line sealing of MPM489
pressure transmitter as an example, it can be directly installed on the
measuring pipe joint. In order to facilitate the installation and
maintenance, should be install shut-off valve between the connector and
the pipeline (see Figure 2).
