Digital Vortex Flowmeter digitaiVT=WFI_a Series The clear path to operational excellence

Series Simple body construction for easy installation and high level of safety Standard Type / Multi-variable Type High Process Temperature / Cryogenic Type Reduced Bore Type Stainless Steel Housing Measurement principle When a shedder bar is placed in a flow, Karman vortices are generated on the downstream side of the bar. The Karman vortices are detected by two piezoelectric elements installed in the upper part of the shedder bar. The vortex frequency is proportional to the flow velocity in a specific range of Reynolds numbers. Therefore, flow velocity or flow rate can be determined by measuring...

Standard Type Reduced Bore Type Yokogawa’s proprietary filter (SSP) for digital signal processing analyzes vortex signals and automatically selects the optimum settings for the best possible measurement. Minimum measurable flow up to five times lower than conventional vortex flowmeter. Integrated construction with reducers built into the flowmeter body. Noise Reduction Noise caused by strong piping vibration may affect the accuracy of vortex frequency detection. The two piezoelectric elements in the digitalYEWFLO are installed in a configuration that is polarized, so they are not affected by...

Multi-variable Type High Process Temperature Version / Cryogenic Version The world’s first two-wire Multi-variable vortex flowmeter (with builtin temperature sensor) can directly output the mass flow rate of saturated steam. For high temperature or cryogenic flow measurement. Measurable temperature range: Maximum 450˚C, Minimum -196˚C Shedder bar with built-in temperature sensor has a temperature monitoring function and a mass flow rate calculation function. z Easy installation and high level of safety with minimum fugitive emission points. z Same face-to-face dimension as the Standard Type z...
