Meter Meter Meter Meter
The meter requires no maintenance under normal operating conditions and when used as
prescribed.
The following visual checks should be carried out at regular intervals in conjunction with the
plant inspections required in hazardous areas to keep equipment in good operating condition:
• Check the meter and, if applicable, the reference vessel for leakage
• Include the liquid level indicator in regular pressure tests of the process vessels (only for
flammable process products).
Depending on the application, worst-case operating conditions may lead to reduced measuring
performance as a result of fouling of the measuring system. Clean the meter in accordance with
the installation and operating instructions for non-explosion proof versions of the product. The
meter must be removed for cleaning. Removing the meter will need to be coordinated with
operating conditions (e.g., check for existence of a flammable liquid or explosive atmosphere in
or at the tank or pressurized tank) and is the responsibility of the operator.
Follow the instructions for removing the entire device refer to
Dismantling on page 20.
