Now featuring an all-welded, no-thread flow element connection for superior reliability, the ST100L Air/Gas In-Line Thermal Mass Flow Meter from Fluid Components International (FCI) provides accurate flow measurement in the most demanding high-pressure industrial operating environments.
The ST100L Flow Meter is an in-line spool piece mass flow instrument developed for precise air/gas measurement. With its all-welded flow element connection the ST100L meter features a high pressure rating of up to 207 bar. It measures a wide range of gases: natural gas, hydrogen, helium, methane, ethane, propane, ethylene, nitrogen, carbon dioxide and many other specialty gases.
The dependable all-welded flow element connection incorporated into the design of the ST100L Flow Meter is inherently thread-less. The elimination of threaded connections removes a potential leak path from standard meter compression fittings, which are threaded and can be a hazardous gas leak source.
The ST100L Flow Meter is a sophisticated thermal dispersion technology air/gas flow meter. It combines feature- and function-rich electronics with advanced flow sensors for advanced air/gas flow measurement. Offering direct gas flow measurement, no additional sensors or flow calculating devices are required for measurement. Its no moving parts design also virtually eliminates wear, breakage and maintenance.
When selecting the ST100L Flow Meter, users have multiple communication options: 4-20 mA analogue, frequency/pulse, or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485.
The ST100L Flow Meter’s electronics include a user selectable and programmable data logger. Readings are stored in a removable, internal micro-SD card. The micro-SD card has a 2 GB capacity capable of storing 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 via the serial port and configuration software tools.
The feature-rich ST100L Flow Meter uses constant power thermal mass flow sensing technology that measure 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 to 305m away. The transmitter enclosure is NEMA4X/IP67 rated and available in painted aluminium or stainless steel.
Approvals available for the ST100L Flow Meter include: FM, FMc, ATEX, IECEx, EAC/TRCU, CPA, NEPSI, InMetro, and CE Approved.
