Multiphase Meter

The simplest and most effective multiphase meter in the market:

  • Non Radioactive solution
  • Real three-phase meter based on mass measurement techniques
  • Two methods of calculations converging to guarantee correct results
  • No need of PVT data information. Only densities are required
  • No flow conditioning requirement
  • It covers the whole range of flow regimes: 0-100% GVF & 0-100% WC without loss of accuracy



WELKER PRODUCTS

ALS Analyzer Liquid Shutoff

The Welker ALS Analyzer Liquid Shutoff prevents any liquid from entering your gas chromatograph, keeping the analyzer columns safe from damage and protecting sensitive equipment from expensive repairs.

Features

  • Fail-safe shutoff in the presence of liquids
  • Sight port for instant visual confirmation of flow status
  • Corrosion resistant material

Benefits

  • Optimizes profitability by protecting sensitive equipment from liquid damage
  • Quick and easy installation Simple maintenance.

F-4 and F-5

The Welker® F-4 and F-5 Filter/Dryers help to remove aerosols, odorant, and liquid hydrocarbons from gas or instrument air. Add a filter to help reduce line freezing, increase instrument performance, and cut down on maintenance. When the filter cartridge becomes saturated, it can easily be removed and replaced. The included standard cartridge contains silica gel (F-4) or a blend of silica gel and activated charcoal (F-5). Other media options are available to suit specialized applications. Supply clean, dry gas or air with the F-4 and F-5 Filter Dryers.

Key Features

  • Spin-on and off filter body simplifies cartridge swaps
  • Filter natural gas to use as an instrument supply source
  • Helps remove water, aerosols, liquid hydrocarbons, sulfur, or odorant based on media selected
