Installation Instructions—wire sensor
The wire sensor is designed for level measurement of liquids in vessels like,
tanks, pump separators and receivers . The sensor can be mounted in a
standpipe from 1" (25mm) up to 4" (100mm) diameter or directly in a vessel
with an inner pipe from 1" (25mm) up to 4" (100mm) diameter. The inner
pipe is needed to create sufficient measuring signal and to avoid a swinging
wire in a lively fluid. To reduce wire movements in larger pipes a special
weight can be used.
The following applies to the design of the system:
•
It must be installed in a vertical position
•
Sensor must have a minimum of 50 mm between the sensor weight end and the bottom of the pipe.
•
The sensor must be installed in an overflow or standpipe where the flow stream and turbulence are minimized.
•
The sensor must be mounted in a standpipe bigger than DN25. Standpipe must be insulated to avoid boiling of refrig-
erant.
•
The outlet pipe from standpipe shall be mounted in an angle of 5-10 degree from horizontal to secure drainage and oil
pockets in refrigeration systems.
•
The sensor is installed and is supplied with a standard non-shielded cable.
If EMC is greater than described in EN 61326, a shielded cable must be used.

Sensor must have a minimum
of 50 mm between the sen-
sor weight end and the
bottom of the pipe.
Drainpipe most be placed at
an angle of 5-10°, to avoid oil
pockets in standpipe.
Special weight for mounting in turbulent
conditions. The steel spacer "star" can be
shortened, using a simple tin cutting shear,
to fit the standpipe. Allow 2 mm play be-
tween inner pipe diameter and "star" di-
ameter
