The ST75 Air/Gas Flow Meter from Fluid Components International is ideal for optimizing the fuel-to-air ratio for plant burner-boiler control, reducing plant fuel costs while protecting the environment in a wide range of industries including chemical, electric power, food/beverage, advanced materials, pharmaceuticals and semiconductor. The flow meter is designed for small line sizes ranging from 0.25 to 2.0 inches (6 to 51 millimeters) and provides three unique outputs: the mass flow rate, totalized flow and media temperature. The meter maintains consistent performance in rugged environments and features accuracy to ±2% of reading with ±0.5% repeatability over varying process temperatures. Its precision flow element has a no-moving parts design that employs platinum RTD sensors embedded in equal mass thermowells with microprocessor electronics calibrated to laboratory standards for a wide range of gases: natural gas, propane, methane, nitrogen CO2, argon, all inert gases, compressed air and more. The meter is equally well suited for low flow and high flow operations and operates over a wide flow range, from 0.01 to 559 SCFM (0.01 to 950 NCMH) depending on line size. For variable process conditions, the ST75 is factory preset to a wide turndown range at 10:1 to 100:1.
