Vortex flow-meter
Vortex PhDâ„¢ EMCO Flow Systems

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
