AMS Instrumentation and Calibration introduces a new range of precision air flow meters from Fluid Components International (FCI), designed to help engineers reduce the energy cost of air compressor systems by measuring compressed air usage more accurately and detecting system inefficiencies or expensive leaks.
FCI’s ST50 flow meter offers a cost effective mass flow monitoring solution ideal for compressed air flow measurement in plants employing point-of-use compressors. Using precision flow measurement, the flow meter helps manufacturing, assembly and process plants reduce air consumables and the energy required to support compressed air systems. FCI’s highly accurate thermal dispersion mass flow sensing technology is used to provide highly effective direct mass flow measurement at a lower cost.
When installed in large facilities with multiple air compressors, the ST50 flow meters allow operators to compare compressor usage and adjust them for optimum efficiencies. Using mass flow meters at the point of compressed air output helps to ensure peak performance at a given flow rate. The ST50 flow meter can also be used to compare the performance of multiple air compressors operating in the same environment, with higher flow rates indicating leaking valves or seals.
ST50 flow meters eliminate the need for temperature sensors, flow computers or any other device required with orifice plates, Venturis, Vortex shedding and other meters.
Key features of ST50 flow meters include built-in temperature compensation for reliable measurement over a wide temperature range with almost no pressure-drop; wide flow range from 0.23 to 122 NMPS for air, compressed air or nitrogen; accuracy at +1% of reading, +0.5% of full scale, with repeatability of +0.5% of reading; operating temperature range of 4°C to 38°C; field-configurable in standard mass flow or volumetric engineering units; dual analogue outputs, 4-20 mA and 0-10 Vdc, field assignable as flow rate or temperature and an RS232C I/O port; and optional 0-1kHz pulse output for totalising flow.
Featuring a rugged stainless steel sensing element with Hastelloy-C tips, the ST50 is designed for endurance and maximum performance in outdoor and field installation conditions. An all-aluminium, epoxy-coated enclosure housing the electronics is NEMA 4X (IP66) rated and withstands operational pressures up to 34 bar (g).
Three process connections, 1/2-inch MNPT or 3/4-inch MNPT with a stainless steel or Teflon ferrule; three field adjustable U-length probes, 152, 305, and 457mm to accommodate pipe sizes 51 to 610mm; and instrument powering options of DC (18-36V) and AC (85-265V) are all available for the ST50 high-accuracy flow meter. The ST50 comes with a 1-year standard warranty.
