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
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.
