Intended use
The Media 05 Differential Pressure and Flow Meter is used to measure and indicate the dif-
ferential pressure or derived measuring variables for gases and liquids. Typical application
include liquid level measurement on pressure vessels, differential pressure measurement be-
tween flow and return flow pipes, pressure drop measurement on valves and filters as well as
flow rate measurement according to the differential pressure method.
The device is designed to operate under exactly defined conditions (e.g. operating pressure,
process medium, temperature). Therefore, operators must ensure that the device is only used
in operating conditions that meet the specifications used for sizing the device at the ordering
stage.
In case operators intend to use the device in other applications or conditions than specified,
contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data for limits and fields of application as well as possible uses.
The Media 05 Differential Pressure and Flow Meter without limit contacts may be used to
measure flammable gases and liquids in which hazardous area conditions of Zone 0 are to
be expected, provided the operator observes the applicable regulations for measuring
flammable gases and liquids in Zone 0. This means that measuring instrument suited for the
connection to Zone 0 can be installed provided:
1. The pipes connecting the instruments have been sized and installed according to the
German Technical Regulations for Flammable Liquids TRbF 50 or
2. Flame arresters or endurance burning flame arresters have been installed in the two
measuring lines.
Whether you have to install flame arresters or endurance burning flame arresters depends
on the conditions on site. However, endurance burning flame arresters are preferably to be
installed. You are required to contact the appropriate regulatory authority to agree on the
necessary measures.
The operator is responsible for meeting the above specified requirements specified (1 and 2).
SAMSON does not assume any responsibility if the operator fails to do so.
