Mounting
Type of probe installation
• Probes are mounted to the process connection with threaded connections or flanges and are
usually also secured with these. If during this installation there is the danger that the probe
end moves so much that it touches the tank floor or cone at times, the probe must, if
necessary, be shortened and fixed down. The easiest way to fix the rope probes is to screw
them to the internal thread on the lower end of the weight. Thread size, see Operating
Instructions on the CD-ROM.
• The ideal installation is mounting in a screw joint / screw-in sleeve which is internally flush
with the container ceiling.
• If installation takes place in a nozzle, the nozzle should be 50 to 150 mm in diameter and
should not be more than 150 mm high. Installation adapters are available for other
dimensions, see Operating Instructions on the CD-ROM.
