Nozzles extending into tank
Caution:
Do not use nozzles that extend into the tank. This will disturb the electromagnetic
emitted pulse and the measurement.
Installation of two devices
If two devices are to be used on the same tank, these should be mounted a distance of at least 2 m
or 6 ¾ ft away from each other. If not, interferences from the electromagnetic (EM) fields generated
by both instruments may cause measurement errors.
Not applicable to coaxial probes - the outer shell of the probe contains the EM field: no minimum
distance required.
Process connection
For the gauge to make accurate measurements:
• The tank process connection must be level.
• Ensure a good fit with the gauge process connection
• The tank roof should not deform under the weight of the gauge
