Class-leading accuracy of new Michell moisture analysers offers peace of mind in custody transfer of natural gas

AMS Instrumentation and Calibration introduces a new range of
high-accuracy moisture analysers designed for companies to meet international
standards of gas quality for transport and use. The new OptiPEAK TDL600 analysers
from Michell Instruments deliver a class-leading moisture measurement accuracy
of ±1% of the reading.

Pipeline networks are highly complex transmission and distribution
systems used to move natural gas across states, countries or even continents. Companies
responsible for these pipelines are required to maintain gas quality within the
requirements of the main international natural gas quality harmonisation
guidelines, including those specified for moisture content.

The new OptiPEAK TDL600 moisture analysers harness the latest
developments in laser spectroscopy to deliver high accuracy of ±1% of the
reading or 1ppmV verified by calibration traceable to NPL (UK) and NIST (US). The
lower detection limit of 1ppmV makes the OptiPEAK TDL600 moisture analyser the
most sensitive instrument in its class on the market, as well as one of the
most reliable.

A unique laser lock system developed by Michell ensures the laser
remains locked to the correct water absorption signal, maintaining a high
integrity measurement at all times.

OptiPEAK TDL600 moisture analysers also employ D-MET, the Dynamic
Methane Compensation System to measure moisture reliably in natural gas with
varying compositions (such as blended gas from multiple fields or following
bio-methane or re-gasified LNG injection) without the need for manual software
correction.
