The ST75 flowmeters from Fluid Components serve fuel gas, inert gas process gas, waste gases and air in small line sizes measurements and are also FM and CSA certified for the reliable use in robust process industry applications.
ST75 Flowmeters
The Media temperature compensation of the ST75 flowmeter offers steady operation and exhibits a precision of ±2 %delivering ±0.5 %repeatability.
It performs accurate flow measurement with no-mobile parts used in its configuration and features platinum RTD sensing devices integrated in identical mass thermowells having microprocessor electronics and are validated to laboratory standards for performing measurements of a wide range of gases including methane, nitrogen, CO2, natural gas, all inert gases, argon, compressed air etc. The flowmeters show a flow range in the order of 0.01 to 559 SCFM or 0.01 to 950 NCMH, based on the line size. The devices exhibit a factory-automated turndown in the order of 10:1 to 100:1 for different process.
Its small line sizes functionality ranges from 0.25 to 2.0 inches. The system is available with three outputs, comprising totalized flow, mass flow rate, and media temperature. The remote-base transmitter shows an entire digital display, which can be fixed up to 50 feet or 15 meters apart from the mass heat flow sensor in the process piping and are interfaced using dual 0.50-inch FNPT wires. The device has a completely scalable 4mA to 20mA and 0- to 10-V standard outputs that can be user-designed to allow flow rate and/or temperature, with a 0 to 1kHz total flow pulse output.
The temperature dispersion technology employed for its operation avoids the necessity of thermal sensing units, flow computers or other systems. The metal, dust and water proof NEMA Type 4X (IP66) enclosure features a sensing component fabricated with 316 stainless steel and Hastelloy-C tips. These unique flow meters are widely deployed for various purposes in numerous industries, including food and beverage, semiconductor advanced materials, chemical, electric power, pharmaceuticals, etc.
