Electrical shock can result in death or serious injury.
Ground device on non-metallic tanks (e.g. fiberglass tanks) to prevent electrostatic charge
build-up.
Single lead probes are sensitive for strong electromagnetic fields and therefore not suitable
for non-metallic tanks.
Care must be taken during transportation of power module to prevent electrostatic charge
build-up.
Device must be installed to ensure a minimum antenna separation distance of 8 in. (20 cm)
from all persons.
Probes covered with plastic and/or with plastic discs may generate an ignition-capable level
of electrostatic charge under certain extreme conditions. Therefore, when the probe is
used in a potentially explosive atmosphere, appropriate measures must be taken to prevent
electrostatic discharge.
Process leaks could result in death or serious injury.
Only qualified personnel should install the equipment.
Install transmitter prior to process start-up.
Install and tighten process connectors before applying pressure.
Handle the transmitter carefully.
Do not remove the transmitter while in operation.
If the process seal is damaged, gas could escape from the tank when removing the
transmitter head from the probe.
Any substitution of non-recognized parts may jeopardize safety. Repair, e.g. substitution of
components etc., may also jeopardize safety and is under no circumstances allowed.
