Fixation of the transmitter
NOTICE
For fixation of the transmitter at the bracket either hexagon head srews (M6x10) or socket
head screws with rubber cap must be used.

Avoid letting the sensor run idle while taking the measurement, e.g. when installed in
front of an air gap to containers in case of filling applications. Doing so may result in
incorrect measurements. To avoid this, install a restriction in the open downpipe or
use an orifice gauge with a diameter smaller than the nominal pipe width.
Each device is tested for pressure prior to delivery.
The installation must ensure a self-draining of the device (see figure below). A vertical
installation is recommended.
An EHEDG compliant process connection requires a combination of process
connections and gaskets according to the latest version of the EHEDG Position
Paper: "Easy cleanable Pipe couplings and Process connections".
For compliance with 3-A sanitary standards, remote transmitter is restricted to
hanging installation, as shown in figure below.
