Mounting two devices
Effects of material influx
Using a protective tube
If two devices have to be mounted on one
tank, they must be spaced at least 2 m
(6.5 ft) apart to eliminate interference and
measurement inaccuracies resulting from
the interaction of the two electromagnetic
fields.
Devices equipped with coaxial probes are
not subject to the above warning because
there is no electromagnetic field outside the
probe's outer sheath.
Do not place the lifter near the material inlet
pipe connector.
Material flowing onto the sensor probe causes
incorrect level indication. If there is not enough
space, it is recommended to install a baffle plate.
The floating lid is a common solution for petrochemicals. In
such cases, the use of a damping tube is recommended.
Straightness and contact of measuring probes
with other fittings and distance from the bottom of the tank.
Using a stirrer
After installation, the cable probes and the associated tensile weight
must be straight, tensioned, and away from other fittings (e.g.,
mixer). They must not come into contact with the tank wall, bottom,
or other objects.
The installation space requirements of the different measuring
probes must be taken into account according to the data of the
measuring probes (see Technical Data).
There is no radiation cone along the probe.
When measuring liquids, the use of a reference chamber or damping tube is
recommended, since it provides mechanical and electromagnetic protection for accurate
measurement.
Protect the device from direct sunlight!
Attaching the probe to the bottom of the tank.
Flexible cable probes can be anchored to the bottom of the tank with a fastener or loop.
Installing and shortening the cable probes
If necessary, the probe can be shortened, but only for liquid applications.
Steps:
1.
Loosen the grub screws (hexagon) with an Allen key. (ISO 2936)!
2.
Pull the cable out of the tension weight and cut to the desired size!
3.
Insert the cable back into the weight as shown and tighten the screws!
4.
Modify the configuration parameters to the new length, the reference point being the
upper edge of the weight!
