Tunable diode laser absorption spectroscopy (TDLAS) is recognized as being the most effective technology for measuring trace moisture in a natural gas stream. It requires passing a state-of-the-art laser through the sample gas and measuring the amount of light absorbed by the water molecules at a specific wavelength before the laser strikes the photo-diode detector. Unlike other measurement technologies on the market, AMI’s innovative approach has significant advantages that make it the premiere choice for the Natural Gas Industry.
Among these advantages are:
Our TDL measurements respond with 90% full-scale in less than 2 seconds in both upscale and downscale, even after an ‘upset’ condition
Our MODEL 4010BR TDL Moisture Analyzer is very stable over temperature, pressure and ‘upset conditions’ and does not require calibration
Our TDL Analyzer or Spectrometer can withstand the harsh, corrosive elements in the natural gas stream because it contains a breakthrough, highly-engineered sample system as part of its design
Natural gas companies have chosen TDL to measure trace moisture levels because the measurement technology responds very rapidly in ‘up & down scale’. However, though TDL-moisture spectrometers have been on the market for years, competitive designs lack many features and options that would enhance ease-of-use or improve the customer experience as part of their standard options package. Additionally, customers feel that the price of these TDL Moisture Analyzers is not often economically viable for their application.
