AMS unveils new high pressure air/gas flow meters

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

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

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.
