Swagelok pipe fitting
The measuring device and the
fi
lter supplied are mounted in the pipe using a ¹
⁄
₄
" Swagelok
pipe fitting.
1. Cut the pipe at a right-angle and deburr it.
2. Push the pipe into the fitting as far as it will go.
3. Tighten the nut finger-tight.
4. Mark the nut at the 6-o'clock position.
5. Tighten the nut. In doing so, observe the following options:
– When mounting for the first time, tighten with
1 ¹
⁄
₄
rotations.
– When mounting a second time, tighten with a
¹
⁄
₄
rotation.
For more information, see the installation instructions for pipe fittings provided by
Swagelok.
Pressure sensor
The measuring device only provides correct measured values when the pressure sensor is
connected. The pressure sensor is already connected when the device is delivered.
‣
Make sure that the pressure sensor is connected correctly.
6.2
Mounting the measuring device
6.2.1
Required tools
For process connections: use an appropriate tool for mounting with Swagelok pipe fittings.
6.2.2
Preparing the measuring device
1. Remove all remaining transport packaging.
2. Remove the protection caps on the inlet and outlet.
6.2.3
Mounting the measuring device
Incorrect device mounting
Burst pipes can cause injury.
‣
Never install the device in the pipe in such a way that it is suspended freely without
additional support.
Mechanical load on the process connections
Pipe forces can affect the vibrations of the micro-channel and thereby impact the accuracy
of measurement.
‣
Avoid high mechanical load on the pipes at process connections.
‣
If mounting on the process pipe, use a wrench to cushion the torque. Do not allow torques
to act on the measuring device.
Blockage of the micro-channel
‣
Install a filter upstream from the measuring device (
15).
1. To ensure compliance with the maximum flow specifications in the measuring device
and the recommended pressure drop across the measuring device, use a bypass line
with appropriate assemblies where necessary (
16).
