Remote Mount Thermal Mass Flow Meter From Fluid Components

The ST50 Remote Mount Flow Meter from Fluid Components International measures air, compressed air or nitrogen and a variety of other processes gases, as well as plant HVAC systems in hazardous areas or difficult-to-reach, equipment-crowded locations.

Featuring an intelligent, no-moving parts thermal mass flow sensor design, the ST50 Remote Mount flow meter measures air flow from 1 to 125 SFPS (0.3 to 38 NMPS), nitrogen from 1 to 150 SFPS (0.3 to 46 NMPS) and compressed air from 4 to 400 SFPS (1.2 to 122 NMPS). Accuracy is +1% of reading, +0.5% of full scale, with repeatability of +0.5% of reading. It operates at temperatures from 40 to 100°F (4 to 38°C).

The ST50’s Remote Mount transmitter, comes with a full digital display, can be mounted up to 50 feet (15 meters) away from its thermal mass flow sensor in the process piping and connected via two 0.50-inch FNPT cables. It may be specified with either an 18-36 Vdc or an 85 to 265 Vac input power supply and is housed in an all-aluminum, epoxy-coated enclosure that is NEMA 4X (IP66) rated. It features a digital display with an LCD screen that is user scalable to flow rate units or as 0-100 percent. Approvals include FM, CSA and CE Mark.

The ST50 is also available with built-in wireless IR communication technology via a standard Palm OS PDA, and is field configurable for flow range in standard mass flow or volumetric engineering units. In addition to the wireless IR I/O, it features dual analog outputs (4-20 mA and 0-10 Vdc), which are field assignable as flow rate or temperature, and an RS232C I/O port. A 0-1kHz pulse output for totalizing flow is also available as an option.
