ST98 Air/Gas Flow Meter from Fluid Components International measures biogases accurately with virtually no maintenance over a long life to provide a lowest lifecycle cost instrumentation solution.
Landfill gas flow is measured at several points in the system to provide landfill operators with critical information for optimal gas production, control, safety and reporting. Landfill gas is primarily a mixture of methane, carbon dioxide, hydrogen sulfide and traces of oxygen, nitrogen, and other gases and water. The ST98 Flow Meter with its thermal mass sensor provides direct mass flow measurement without the need for additional temperature or pressure sensors or density calculating devices. The meter’s insertion style configuration makes it simple to install in existing piping without cutting the pipe or welding, offering minimal interruption to plant operations.
With its rugged no-moving parts sensor design, the ST98 meter is suitable for service in biogas and natural gas, as well as numerous other process gases, hydrocarbon mixed or dirty gases and plant compressed air and HVAC systems.
The ST98 meter’s transmitter converts the differential temperature signal to a standard 4-20 mA output signal. The meter’s transmitter with its RS232C communications port is housed in either a NEMA Type 4 or Type 4X (IP66) enclosure that is explosion-proof and can be integrally mounted to the flow element or remotely mounted up to 500 feet away. In addition, an LCD display screen indicating flow rate, temperature and totalized flow is available as an option.
