Elster® EnCal 3000 BTU Analyzer
Brand: Honeywell Process SolutionsHoneywell Elster® EnCal 3000 is a gas chromatograph analyzer specially designed for natural gas energy measurements.
This state-of-the-art analyzer uses chromatography components based on the latest Micro-Electro-Mechanical Systems - MEMS.
In natural gas energy measurement, calorific value is a key component that determines the energy content flowing through a pipeline, along with volume, pressure, and temperature measurements.
EnCal 3000 helps gas transmission & distribution companies as well as end-users consuming large amounts of gas accurately measure of single gas components since wrong measurements can directly impact the bottom line.
EnCal 3000 analyzer injects natural gas into a carrier gas stream that further proceeds to a column where natural gas is separated into its constituents.
The separated constituents then pass a calibrated detector in peaks and the area of these peaks is dependent on the constituent’s concentrations.
With collated data from the constituent’s concentrations, the heating value / Wobbe-index / density of the natural gas is calculated
