The Wedge Meter: Mediedro

Product Summary

The Mediedro is a pressure differential flow measurement instrument designed according to the ISO-5167:6 guidelines. It is particularly suitable for measuring viscous, dirty, and/or laden fluids.

Main Features:

  • Application in Viscous Fluids: Designed for precise measurement in viscous fluids.
  • Use of Seals: Prevents clogging or damage to the pressure transmitter.

Operation:The Mediedro, like other orifice meters, operates based on the principle of pressure differential. It has a segmental wedge that creates an "H"-shaped opening at the bottom of the tube. This opening causes a pressure differential between the upstream and downstream taps, and through appropriate calculations, this pressure difference is used to measure the flow of the fluid in question.

Main Applications:
  • Oil and Gas
  • Petroleum Refineries
  • Chemical and Pharmaceutical Industry
  • Food and Beverage Industry
  • Mining and Energy
  • Pulp and Paper Industry
  • Steel Industry

Technical Specification:

  • Uncertainty: ±4%, for greater precision, calibration according to standards is required.
  • Repeatability: 0.1% (dependent on the transmitter)
  • Rangeability: 10:1
  • Standard H/D Ratios: 0.3; 0.4; 0.5.
  • Pressure Loss: Dependent on ΔP and H.
  • Straight Run Requirements: Refer to the technical specifications table.
