Fluid Components International ST98 air/gas flow meter

Sunday, 12 April, 2015 | Supplied by: AMS Instrumentation & Calibration Pty Ltd


The ST98 air/gas flow meter from Fluid Components International allows facility engineers to monitor and control the precise amount of fuel needed to run HVAC boilers efficiently.

The meter’s thermal mass flow sensor design provides direct mass flow measurement without the need for additional temperature or pressure sensors or density-calculating devices. Its insertion-style configuration makes the meter simple to install in existing piping.

The meter is suitable for service in plant natural gas and other process gases; hydrocarbon-mixed or dirty gases; biogases including methane; and plant-compressed air and HVAC systems.

The flow meter’s accuracy is ±1% of reading, plus ±0.5% of full scale, with repeatability to ±0.5% of reading. The flow range is from 0.21 to 172 NPS in air at standard conditions.

The thermal mass flow sensing element is constructed with two all-welded 316L stainless steel thermowells, protecting two matched platinum precision resistance temperature detectors (RTDs).

The meter’s transmitter converts the differential temperature signal to a standard 4-20 mA output signal. The transmitter and its RS232C communications port are housed in either a NEMA Type 4, Type 4X (IP66) enclosure or an explosion-proof enclosure, and can be integrally or remotely mounted

With no moving piece construction, the meter is unaffected by plant vibration and there is virtually no maintenance or recalibration required. The meter features a broad range of agency approvals: FM, ATEX, IEC, CSA, CRN, GOST/RTN, NEPSI, CPA, PED and CE Mark (system approvals).
