Features & Benefits

Patented Cell Block For An Incredibly Compact Leak-Free Design

A low volume Herriott cell has been directly mounted to our patented ELIMINATOR CELL BLOCK™. This combination provides a very compact and complete sample system approach. Precision cross-drilled intersecting gas passages eliminate the need for long lengths of tubing and leak-prone compression fittings. Additionally, we have integrated a liquid rejection membrane, bypass metering valve, flow control metering valve, and flow meter into the compact set of blocks. Sample gas travels a short 4” distance from the compression fitting prior to entering the measurement cell, resulting in the industry’s fastest and most reliable measurement.

Proprietary TDL Technology

AMI’s patented Tunable Diode Laser (TDL)-based technique for moisture measurement is noninvasive, with no sensor in contact with the sample gas that can become contaminated or cause drift. This means unmatched performance for ultra-fast response times, accuracy, and reliability, with no cross interferences with other gases in the stream, including mercaptans, alcohols or heavier hydrocarbons.

Unmatched Reliability – The First Time And Every Time

AMI’s non-contact TDL technology means the factory calibration remains stable over time. Long-term reliability is further enhanced by AMI’s proprietary analysis software that provides a quick and simple adjustment to correct for any long-term laser power drifts or zero level drifts. Prior to shipment, every Analyzer undergoes an intense battery of performance tests over its entire range for pressure, temperature and linearity specifications to ensure the unit meets our strict quality control standards.

Optimized Optical Cell

Sample gas flows through AMI’s compact multi-pass optical absorption cell, or Herriott cell. This special cell contains two plano-concave mirrors at each end of a precision-machined block with small holes in each mirror to couple incoming and outgoing light. The AMI design minimizes the volume of sample gas in the Herriott cell and eliminates any air gaps between the laser output and the detector, ensuring that only H2O within the space between the two mirrors is measured. AMI further enhances its measurement technique by utilizing wavelength modulation spectroscopy (WMS) to increase sensitivity and reduce noise. The result is a small-volume sample cell with an optimized optical absorption path length, tailored specifically for the measurement of H2O in natural gas over the 0.25 to 20 lb. range.
