Yokogawa releases OpreX vortex flowmeter VY series


Yokogawa Electric Corporation announces the release of the OpreX™ Vortex Flowmeter VY Series. These flowmeters comply with major explosion-proof standards (IECEx, ATEX, FM, FMc) and are SIL2 certified. The new product series, which is part of the OpreX Field Instruments family, will be released first in Southeast Asia, Oceania, India, the Middle East, and South America, excluding Brazil. It will be rolled out in other markets after compliance with each countries’ standards has been certified. When used in combination with specialized software that is sold separately, the OpreX Vortex Flowmeter VY Series supports remote maintenance functions that enable planned and efficient condition-based maintenance.


Enables calculations by the flowmeter itself
Utilizing readings from a built-in temperature sensor and data from pressure gauges and other external instruments, the VY Series of vortex flowmeters can perform precise temperature and pressure-compensated calculations and energy calculations, eliminating the need for external calculation devices.

Enhanced self-diagnostics and condition-based maintenance through DX
The digitalization of internal signals is taken further in the VY Series, enabling self-diagnostics to cover all components, including the vortex shedder bar and sensor element. This improves reliability and qualifies these flowmeters for use in safety instrumented loops (compliant with SIL2).

A unique and proven design
The sensing mechanism, face-to-face lengths, and the size range (from 15mm to 400mm), are fully compatible with previously released YEWFLO Series products, so individual devices can be replaced without the need for additional piping work. The vortex shedder bar has a robust and integrated design, and is the only such device in the industry to feature dual built-in flow sensors and a built-in temperature sensor.
