American Meter pressure regulators are used (a) upstream
of a gas meter to reduce inlet pressure to the meter and
eliminate fluctuations which can affect meter accuracy
and (b) downstream from the meter to provide reduced
pressure for gas operated equipment.
Factors which determine the selection of a regulator
are:
1)
inlet pressure to the regulator
2)
outlet pressure which the regulator must maintain
3) the
required capacity of the regulator in btu/hr or cfh
4)
type of gas, eg, natural gas or propane
Regulators frequently include options for the protection
against upset conditions. The most common of these
include:
- OPSO-overpressure
shutoff: the ability to shut down the gas supply if
outlet pressure exceeds a predetermined value
-
UPSO-underpressure shutoff: the ability to shut down the
gas supply if outlet pressure falls below a
predetermined value - partial or full capacity internal relief: the ability to maintain downstream pressure under upset conditions by venting excess gas to the atmosphere. |
