Fluid Components' ST75 Air/Gas Flow Meter is engineered to ensure an accurate and low-maintenance measurement solution
The ST75 Air/Gas Flow Meter from Fluid Components International (FCI) is designed to optimize the fuel-to-air ratio for plant burner-boiler control. The ST75 Flow Meter from FCI is designed for line sizes ranging from 0.25 to 2.0 inches (6 to 51 millimeters). The ST75 meter provides three outputs: the mass flow rate, totalized flow and media temperature.
The ST75 meter is made for 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 range of gases: natural gas, propane, methane, nitrogen CO2, argon, all inert gases, compressed air and more. The ST75 Flow Meter is suited for low and high flow operations and operates over a flow range from 0.01 to 559 SCFM (0.01 to 950 NCMH) depending on line size.
The ST75’s Flow Meter’s remote mounting capabilities are engineered to ensure an accurate and low-maintenance measurement solution for small line size gas and air flow applications in hard-to-reach locations. It is made for hazardous factory areas and crowded plants where explosive, flammable or toxic gases may be present near transmitting electronics. The remote mount transmitter, which includes 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 or M conduit connections.
The ST75 Flow Meter’s fully scalable dual 4-20mA standard outputs are user assignable to flow rate and/or temperature and a 0-1kHz pulse output of total flow. The instrument can be ordered for input power with either 18 to 36 Vdc or 85 to 265 Vac, with or without a built-in LCD digital display.
