Mass flow meter
Sierra Instruments, Inc. has introduced an ultra-high-purity gas mass flow meter for bulk gas delivery service in semiconductor, pharmaceutical and other ultra clean applications. The new flow meter, Model 760-UHP, is constructed of 316 stainless steel tubing with a 7-10 RA interior finish. The ends of the tubing are prepped for orbital butt welding. The sensor and transducer electronics are designed for easy removal, service or replacement via VCR fittings. The Model 760-UHP delivers direct reading of gas mass flow rate, independent pressure, or temperature changes in the gas stream. The measurement principle is the most stable, reliable and accurate method available for bulk gas flow measurement applications, and does not exhibit the zero drift tendencies typical of capillary-type mass flow meters and controllers.
