AMETEK' PROCESS INSTRUMENTS MEASURES: SO2/ NO, NO2 or H2S with mass flow PRODUCT DATA SHEET 909 Hot/Wet Single Gas Mass Flow CEM Specifically configured for monitoring stack emissions on a mass rate basis The AMETEK 909 is a single gas continuous emissions monitoring (CEM) system that measures stack effluent temperature and velocity, in addition to pollutant concentrations at stack conditions, enabling mass emission rates to be reported. With the addition of an optional zirconium oxide (ZrO2) sensor, the 909 is also capable of monitoring oxygen (O2). The sample cell and all components in contact with the sample are heated above the dew points of all gases in the sample stream. This results in a more accurate calculation of gas concentrations, compared to other CEM systems that require water removal or sample dilution. No corrections for condensed and dissolved components are required. It also results in a simpler, more reliable analytical system as there is no need for sample drying. The 909 has built-in zero and span calibration and four zone temperature control (sample line, probe, sample conditioning unit, and oven). Full function CEM As a full function CEM, the 909 performs all necessary sample gas and calibration gas flow management, as well as probe and sample line temperature control. Simply add a sample probe and sample line to be fully operational. Maximum reliability and durability With a no-moving-parts design, the 909 is built for maximum reliability and durability. It is a complete system with a sample extraction and transport system designed to ensure sample integrity. High resolution ultraviolet (UV) technology With a dual beam, dual wavelength configuration, a resolution of better than 0.02nm is provided by high-intensity line source lamps, enabling unparalleled linearity over a wide dynamic range, and leading to very accurate measurements. The dual beam configuration, combined with the reference measurement, ensures low noise performance with minimal baseline and span drift. • High reliability and reduced maintenance (no moving parts) • Sample and mass flow measurement in one device • Hot/Wet analysis - no water compensation or correction factors required • Accuracy better than 2.5 parts per million (ppm) SO2 • No water (H2O) or carbon dioxide (CO2) interference • Automated zero and span gas calibration • Incorporates flow measurements for emission rate calculations B5I APPLICATIONS • Sulfur recovery incinerators • Sulfuric acid plants • Gas processing sulfur recovery To find out more or request a quote visit our website AT ametekpi.com
