WLR meter: microwave water cut (water liquid ratio) meter for multiphase wellhead streams by Pietro Fiorentini
Water Content Meter

WLR Meter Microwave Water Cut (WLR) Meter

The WLR Meter is a modular, inline system for real-time measurements of water content in multiphase flow. The sensor utilizes microwave quarter-wavelength coaxial resonator technology with a high-pressure dielectric window that calculates permittivity and conductivity to determine water content. Available as a standalone unit or integrated within a multiphase flow meter.

Frequently asked questions

What is the difference between water cut and WLR?

Both describe the share of water in the liquid phase of a well stream. WLR stands for water liquid ratio, and in multiphase metering the two terms are used for the same measurement. The WLR Meter is Pietro Fiorentini's water cut meter: it measures 0 to 100 percent WLR in streams from 0 to 100 percent GVF.

How does a microwave water cut meter measure water content?

The sensor is a microwave quarter-wavelength coaxial resonator with a high pressure dielectric window exposed to the process. By scanning the resonance frequency, the meter calculates the permittivity and conductivity of the fluid and from them the water content. It can be supplied stand-alone or built into a multiphase flow meter such as the Totem or Xtreme S.

Can you supply the WLR Meter for fields in the GCC?

Pietro Fiorentini Saudi Industry in Al Khobar supplies and supports the WLR Meter, from 2 to 14 inch and rated to 345 bar, for oil and gas fields in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Share your line size and process conditions to get a quotation.
