Combined with highreliability and robust design, it delivers improvements inplant efficiency and reduced operating Multi-Variable Type (OPTION:/MV)build in temperature sensor, so that temperaturemeasurement and Mass Flow calculation is Reduced Bore Type (OPTION:/R1, /R2)Integrated and casting construction with concentricreduced bore benefits piping cost reduction and lower flow range.

2 * SSP is YOKOGAWA s original technology for digital signal processing. FEATURES New functions with SSP (Spectral SignalProcessing) technology :SSP is built into the powerful electronics ofdigitalYEWFLO. SSP analyses the fluid conditionsinside digitalYEWFLO and uses the data toautomatically select the optimum adjustment for theapplication, providing features never beforerealized in a vortex accurately senses vortices in the low flowrange, providing outstanding flow stability. Advanced Self-diagnostics :The application condition, such as high pipelinevibration and abnormal flow, is predicted andindicated.

3 High Accuracy : of Reading (Liquid)( of Reading : Typical Accuracy/ Non-Guaranteed) 1% of Reading (Gas, Steam) Wide Process Temperature Range : High temperature version up to 450 C Cryogenic version minimum 196 C Simple Parameter settings :Frequently-used selections grouped together in aquick-access format decreases commissioning time. Clear, Concise Indicator :Simultaneous flow rate or temperature (Option) andtotal flow rate along with process diagnosisconveniently displayed. Dual output for Analog / Pulse:Simultaneous output for flow rate or temperature(Option) and pulse. Alarm output, Status output (Flow switch)An alarm signal output, in case alarm occurs.
