Thermal Mass Flowmeter for Rugged Applications
Fluid Components has introduced the ST100 series thermal mass flowmeter, designed for process and plant gas flow measurement applications. The ST100 is able to continuously measure, display and transmit an extensive array of parameters and is designed with a migration path so instrument, process and plant engineers have the flexibility to adapt to plant and control technology they might deploy in the future. Whether the need is for conventional 4-20mA analogue, frequency/pulse, alarm relays or advanced digital bus communications such as HART, Foundation Fieldbus, Profibus or Modbus, the ST100 is the solution.
If a plant's needs change over time, the ST100 flowmeter adapts as necessary with a plug-in card replacement that can be changed out by plant technicians in the field. The ST100 flowmeter features a graphical, multivariable, backlit LCD display, which provides information with continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics. The ST100 measures gas mass flow rate, total flow, temperature and pressure, depending on the model range. It stores up to five calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1,000:1 turndown.
An optional Spectracal gas equivalency calibration method allows the user to select and switch between 10 common gases. Also standard is an on-board data logger with an easily accessible, removable 2GB micro-SD memory card capable of storing 21 million readings. With the ST100, Fluid Components offers three different types of flow sensors to best match user applications. The FPC style is a fast-response type that features an integral flow conditioner and protective shroud optimised for compressed air and clean gas applications. The FP style is a fast-response, general-purpose design with a protective shroud and is also the sensor used with Fluid Components' Verical in-situ calibration option.
For applications with wet or dirty gases or erratic flows, the unshrouded S-style facilitates easy cleaning and provides a smoothed response. The ST100 series is comprised of two core model ranges: the ST and STP. The ST range measures mass flow and temperature, and the STP range measures mass flow, temperature and pressure. Both ranges include single-point and dual-element models as configurations outfitted with Fluid Components' Verical in-situ calibration option. The ST100 can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases. The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.25-1,000sfps (0.07-305nmps) with accuracy of +/- 0.75 per cent of reading, +/- 0.5 per cent of full scale.
ST100 flowmeters are designed for rugged industrial process and plant applications, including service up to 454C. Both integral and remote (up to 1,000ft) electronics versions are available. The ST100 is agency approved for hazardous environments, including the entire instrument, the transmitter and the enclosure. Instrument approvals (submitted and pending) include: FM and FMc: Class 1, Division 1, hazardous locations, Groups B, C, D, E, F, G; ATEX and IECEx: Zone 1, II 2 GD Ex d IIC T4; the rugged enclosure is NEMA 4X/IP67 rated.
