Emissions from sources, such as large boilers, steam generators, furnaces and process heaters generate a great deal of gaseous emissions (primarily NOx and CO). Many Air Quality Management Districts are regulating these devices to limit the associated air pollution, and health dangers. For example, in California, the Sacramento Metropolitan Air Quality Management District (AQMD) instituted Rule 411 to limit the associated NOx and CO emissions from these devices. One requirement of the rule is to continuously monitor each fuel line’s consumption with a temperature and pressure compensated flow meter that has a non-resettable totalizer. And in the County of San Joaquin, CA, the Air Pollution Control District (APCD) instituted Rule 4702 that requires measurement of fuel gas by a non-resettable fuel meter.
In New Jersey, the NJ Dept. of Environmental Protection (NJDEP) promulgated a new, more rigorous rule requiring all Boilers rated at Five Million BTUs (150 HP) or above to perform an annual combustion adjustment to minimize emissions, and to report the annual fuel usage of each boiler line over a 12 month period. The Sage Prime Thermal Mass Natural Gas Flow Meter meets this requirement to measure annual flow consumption. This regulation, Rule 2008-12A is in effect on January 1, 2010.
The Sage Prime Natural Gas Thermal Mass Flow Meter, with a non-resettable totalizer meets these requirements. The Sage Prime Flow Meter is offered in Integral or Remote Style
(which has lead-length compensation up to 1000 feet as well as an
Explosion Proof Junction Box). Specify any standard probe length
or flow body size. It has a 4-20 ma output as well as a Pulsed Output
of Totalized Flow (solid state [sourcing] transistor drive). In addition,
Sage Prime supports full Modbus® compliant RS485 RTU communications
(IEEE 32 Bit Floating Point).
