As a member of the Profibus International Organization (PNO), the FCI ST98 flowmeter is fully approved with Certification Number Z01212.
The ST98 advanced thermal dispersion mass sensing element with highly intelligent digital electronics delivers precision flow and temperature measurement over a wide flow range.
It features high accuracy to +/-1% of reading, plus +/-0.5% of full scale.
Exceptionally consistent, the ST98 offers repeatability to +/-0.5% of reading.
The inline style ST98 features an exceptionally wide flow range from 0.00062 to 1850 SCFM [0.01 to 3140 Nm3/h] in air at standard conditions for 70F [21.2C] and 14.7 psia [0C and 1013,25 bar(a)], typical for most gases.
The ST98 offers low-flow sensitivity yet is able to operate from 10:1 to 100:1 turndown ratio and is field adjustable within the calibrated range.
The ST98 is an exceptionally versatile and reliable flowmeter.
It is suitable for service in numerous process gases, hydrocarbon mixed or dirty gases, biogases including methane, and plant compressed air and HVAC systems.
The ST98 has been installed in plants worldwide, including a wide range of industries such as chemical, energy production, food/beverage, oil/gas, pharmaceutical, pulp/paper, steel, wastewater treatment and more.
The ST98 thermal mass sensing element is comprised of two all-welded 316L stainless steel thermowells that protect two matched platinum precision resistance temperature detectors (RTDs).
With a highly reliable no-moving parts design, one RTD is heated relative to the reference RTD, and the temperature difference between the two is related to the process gas mass flow rate.
The ST98 transmitter converts the differential temperature to a standard 4-20 mA output signal that has been linearised during the FCI factory NIST traceable calibration of the flow element.
The ST98 transmitter with its RS232C communications port is housed in either a NEMA Type 4, Type 4X (IP66) enclosure or an explosion-proof enclosure 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 totalised flow is available as an option.
