Installing the flowmeter sensor DN 1.5 (1/16”)
Horizontal installation is recommended. If vertical installation is
required, a flow direction from below to above is recommended for
better elimination of air bubbles. In order for air to be removed from
the flowmeter sensor, the flow speed in the flowmeter sensor must be
at least 1 m/s. If the fluid contains solid particles, especially in
conjunction with too little flow, a level installation location of the
flowmeter sensor and positioning of the input flange completely on
top is recommended so that the particles can be more easily flushed
out. In order to avoid a partial emptying of the flowmeter sensor, a
sufficient back pressure must be present at the unit (min. 0.1 … 0.2
bar/(1.45...2.9 psi)).
•
Install the flowmeter sensor in a vibration-free manner to a wall or
a steel frame.
• Position the flowmeter sensor at a low location in the system in
order to avoid a negative pressure in the flowmeter sensor, that
could lead to air or gas separation in the fluid.
• Ensure that the flowmeter sensor is not run empty (in the normal
operation) as this can lead to inaccurate measurements.

High temperature version
In the high temperature design the multi-connection plug is separated
from the sensor housing by a pipe. Thereby the plug can still be
accessed even when the sensor is insulated.

Important
If there are large differences between the fluid and ambient
temperature the sensor must be insulated, to prevent two
phase flow and accuracy effects. This is especially important
for low flowrates.
The sensor must
always be completely filled with
homogeneous liquid or a single phase gas, otherwise the
accuracy could be adversely affected.
For air/gas in volatile fluids horizontal installations are
recommended.
The mounting bracket included with the shipment should always be
used. The bracket should be secured to a wall or a steel framework
(vibration free and mechanically stable).

Angle multi-connection plug, horizontal
To achieve optimum performance, the multi-connection plug is to be
installed as shown in the figure. The multi-connection plug can be
rotated within the angle noted.
