Impurities inside a pipeline system carried by gas may cause mechanical damage to the gas
meter or at least reduce its measurement accuracy. Therefore, a filter with efficacy not worse
than 10 m should be installed upstream the gas meter (particularly when the flowing gas
contains high amounts of impurities). In addition, the inflow side of the system should be
thoroughly cleaned before installing the gas meter. Conical sack filter may be placed
on the inlet of the inflow section; the filter should be removed after 1 2 months of operation.
If the filter is not removed, monitoring of the filter impurity level should be provided
by means of pressure drop measurements or regular check-ups. If clogged, the sack filter may
be destroyed by the gas pressure, and filter debris may seriously damage the gas meter.
