AMS Instrumentation and Calibration announces the release of a new range of inline air/gas flow meters featuring an all-welded, no-thread connection and suitable for high pressure applications in demanding industrial environments.

The new Model ST100L air/gas inline thermal mass flow meters from Fluid Components International (FCI) is recommended for high pressure applications in oil and gas, chemical, and power generation sectors among others.

Delivering excellent reliability with the all-welded, no-thread flow element connection, Model ST100L thermal mass flow meters provide accurate flow measurement in demanding high-pressure industrial operating environments. An inline spool piece mass flow instrument developed for precise air/gas measurement, Model ST100L flow meter features a high pressure rating of up to 207 bar (g) and is capable of measuring a wide range of gases including natural gas, hydrogen, helium, methane, ethane, propane, ethylene, nitrogen and carbon dioxide among many other speciality gases.

The thread-less design of the dependable all-welded flow element connection incorporated into the design of the ST100L flow meter removes a potential leak path from standard meter compression fittings, which are threaded and can be a hazardous gas leak source.

Designed as a sophisticated thermal dispersion technology air/gas flow meter, the ST100L flow meter combines feature- and function-rich electronics with advanced flow sensors for advanced air/gas flow measurement. By offering direct gas flow measurement, the ST100L eliminates the need for additional sensors or flow calculating devices.

Key features include no-moving parts design virtually eliminating wear, breakage and maintenance; multiple communication options comprising of 4-20 mA analogue, frequency/pulse, or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485; and graphical, multivariable backlit LCD display offering sophisticated readout that continuously displays all process measurements and alarm status for easy on-site viewing by technicians.

A user selectable and programmable data logger in ST100L flow meter stores the readings in a removable, internal micro-SD card with a 2GB capacity or approximately 21 million readings. Recording time base is user selectable with a maximum rate of 1 reading per second. The logging feature is selectable via the front panel menu or the serial port and configuration software tools.

The feature-rich ST100L flow meter utilises constant power thermal mass flow sensing technology that measures flow with 100:1 turndown in ranges from 0.01 to 3140 NCMH. The transmitter/ electronics can be integrally mounted with the flow body or may be remote mounted up to 305m away. The transmitter enclosure is NEMA4X/IP67 rated and available in painted aluminium or stainless steel.

ST100L flowmeters are agency approved for hazardous environment installations. FCI products undergo rigorous agency testing and obtain their approvals on the entire instrument, not just the enclosure. Approvals available for the ST100L flow meter include FM, FMc, ATEX, IECEx, EAC/TRCU, CPA, NEPSI, InMetro, and CE.
