DigitalYEWFLO Vortex Flowmeter High process Temperature Version / Cryogenic Version (DY-HTLT)
  The long term reliability of the digitalYEWFLO series also extends to the High Process Temperature and Cryogenic models.
Description

  一、 Product Information

  The long term reliability of the digitalYEWFLO series also extends to the High Process Temperature and Cryogenic models.

  With the High Process Temperature model, process fluids with temperatures as high as 450 degrees C can be accurately measured, this is ideal for your high temperature superheated and saturated steam applications.

  The Cryogenic model can measure processes at temperatures down as low as -196 degrees C, ideal for low temperature applications such as liquid oxygen.

  二、 Features

  - New functions with Spectral Signal Processing (SSP) technology

  SSP analyses the fluid conditions inside the digitalYEWFLO vortex flowmeter and uses the data to automatically select the optimum adjustment for the application, providing features never seen before in a vortex flowmeter.

  SSP accurately senses vortices in the low flow range, providing outstanding flow stability.

  - Advanced self-diagnostics

  Application conditions such as high pipeline vibration and abnormal flow are predicted and indicated.

  - High accuracy

  ±0.75% of reading (liquid)

  ±1.0% of reading (gas, steam)

  - Wide process temperature range

  High temperature version up to 450 deg C

  Cryogenic version minimum -196 deg C

  - Simple parameter settings

  Frequently-used selections grouped together in a quick-access format decrease commissioning time

  - Clear, concise indicator

  Convenient display of the simultaneous and total flow rates together with the process diagnosis

  - Dual output for analog/pulse

  Simultaneous output for flow rate and pulse

  - Alarm output

  An alarm signal is output when an alarm occurs.

  - BRAIN/HART communication and key switches for human-machine interface

  - NACE compliant

  - NAMUR 43 compliant

  - Remote cable length up to 30m
