Features

  • Ideal for high static pressure applications (e.g. upstream oil & gas, highpressure steam, boiler feed).
  • Excellent long-term stability reduces calibration burden and cost.
  • Flexible communication and diagnostics make it easy to integrate and maintain in modern control systems.
  • Combined DP + SP measurement helps reduce the number of devices needed.
