Air/Gas Mass Flow Meter Point Measurement

February 6, 2013

FCI-ST75-Gas-CompressorsThe rugged ST75 Flow Meter from Fluid Components International (FCI) delivers precision flow measurement while reducing the consumption of energy fuel gases, specialty gases and pneumatic air. Installing ST75 Flow Meters in large process industry facilities and assembly plants with multiple gas compressors allows the operators to compare compressor usage and adjust them for optimum efficiencies. In addition, the use of mass flow meters at the point of compressed gas output helps to ensure peak performance at a given flow rate.  Comparing the performance of multiple gas compressors is also useful in predictive maintenance applications where higher flow rates may indicate leaking valves or seals in one unit versus other units operating under similar conditions. The ST75 Flow Meter is designed specifically for demanding process industry and manufacturing assembly plant environments with its rugged and highly reliable, proven performance. To ensure reliable performance under variable process and plant temperature conditions, the ST75 Flow Meter’s design includes media temperature compensation. It offers accuracy to ±1% of reading and ±0.5% repeatability. Its precision flow element has a no-moving parts design that employs platinum RTD sensors embedded in equal mass thermowells with microprocessor electronics that can be calibrated to laboratory standards for CO2 as well as many other gases.
