EMCO's model Vortex PhD® is an in-line vortex shedding flow meter capable of measuring liquids or gases, including steam, for pipe sizes from 1" to 12", available in stainless steel and carbon steel. The PhD flow meter has no moving parts, rugged construction, and microprocessor-based electronics for high accuracy in many flow metering applications. The Vortex PhD flow meter, with no moving parts, provides accurate measurement with lower maintenance, and lower total cost of ownership than other flow meter technologies. Features Accuracy * ± 0.7% of rate accuracy for liquids * ± 1.0% of rate accuracy for gas and steam * ± 0.15% of rate repeatability * Advanced digital filtering scheme used by the microprocessor ensures accurate and reliable flow measurement and control * Calibration is traceable to NIST Reliability & Safety * No moving parts or holes that can clog * No internal gaskets that could fail and cause hazardous leaks * The industry's first fully-welded sensor construction * Sensor can be removed under full-flow conditions without process shutdown or risk of exposure to hazardous fluids * No need for bypass piping installation * FM, CSA, and CENELEC approvals Ease of Operation * Factory calibrated and programmed for specific applications * Setup and use without any additional calibration or programming * The local display alternates between flow rate and totalized flow * Menu-driven EZ-Logic™ user interface enables local programming * HART® protocol communication
