GH-6062E Intelligent Flue Gas Velocity & Humidity Analyzer

Overview

The GH-6062E Intelligent Flue Gas Velocity & Humidity Analyzer is a field-deployable, integrated environmental monitoring instrument engineered for simultaneous, real-time measurement of flue gas velocity, volumetric humidity, static/dynamic pressure, and gas temperature in industrial exhaust streams. It operates on two complementary physical principles: capacitive-resistive hygrometry for accurate moisture quantification across a wide dynamic range (0–40 vol%), and Pitot tube-based differential pressure sensing for velocity derivation under ISO 5167-compliant flow conditions. Designed explicitly for demanding stack and duct environments—including high-temperature (>150 °C), high-humidity (>90% RH), high-dust loading (>10 g/m³), and chemically aggressive atmospheres (e.g., SO₂, HCl, NOₓ)—the analyzer incorporates full-length heated sampling probe technology to eliminate condensation-induced sensor drift and ensure metrological integrity throughout extended field campaigns.

Key Features

• Heated sampling probe with uniform thermal profile (up to 180 °C) prevents water condensation and maintains sensor calibration stability during high-humidity sampling.
• Capacitive-resistive humidity sensor sourced from a Tier-1 European OEM, offering long-term repeatability (<±1.5 vol% RH over 12 months) and minimal hysteresis.
• Integrated Pitot-static probe assembly with dual differential pressure transducers enables direct calculation of gas velocity, volumetric flow rate, and mass flow (when combined with temperature and cross-sectional area inputs).
• High-resolution color TFT display (≥320 × 240 pixels) supports real-time visualization of all measured and derived parameters—including average velocity, mean static pressure, dew point estimation, and normalized flow volume.
• Onboard microprocessor performs automatic zero-point correction, linearization, and compensation for barometric pressure and gas composition (default air; configurable for CO₂-rich or N₂-diluted streams).
• Non-volatile flash memory stores up to 100,000 timestamped measurement records with full metadata (date/time, GPS tag if enabled, operator ID, probe ID, ambient conditions).
• Built-in Bluetooth 4.2 module enables wireless data export to certified field tablets or laptops running Genetc’s PC Utility Software; optional RS232 port supports direct connection to thermal printers or SCADA gateways.

Sample Compatibility & Compliance

The GH-6062E is validated for use in fixed emission sources compliant with China’s national environmental monitoring standards: GB/T 11605–2005 (humidity metrology), GB/T 16157–1996 (particulate and gaseous pollutant sampling methodology), and JJG 680–2007 (verification procedures for particulate samplers). Its mechanical design conforms to IEC 60529 IP54 ingress protection requirements for dust and water resistance. While not intrinsically safe or explosion-proof (ATEX/IECEx non-certified), the unit meets electromagnetic compatibility (EMC) Class B limits per GB/T 17626 series and operates reliably in electrostatic-prone environments due to grounded probe shielding and isolated signal conditioning circuits. Optional O₂ sensor integration (electrochemical cell, 0–25% vol) allows stoichiometric combustion efficiency evaluation per GB 13223–2011.

Software & Data Management

Genetc’s proprietary DataLink Pro software (Windows 10/11 compatible) provides secure, audit-ready data handling in accordance with GLP-aligned workflows. Features include encrypted database import/export (CSV, XML, PDF report generation), user-access level control (admin/operator/viewer), electronic signature support, and full audit trail logging for all calibration events, parameter edits, and data exports. The software complies with FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with configured authentication protocols. Raw sensor outputs (mV, Ω, Hz) are preserved alongside processed values, enabling traceable recalibration and uncertainty budgeting per GUM (JCGM 100:2008).

Applications

• Continuous compliance monitoring of coal-fired, biomass, and waste-to-energy power plant stacks.
• Performance verification of wet flue gas desulfurization (WFGD) systems—particularly post-scrubber humidity and velocity profiling.
• Emission testing in petrochemical refineries, ethylene crackers, and catalytic reformers where acid gas corrosion and particulate fouling challenge conventional probes.
• Process optimization in tobacco curing tunnels, industrial drying ovens, and climate-controlled environmental test chambers.
• Regulatory stack testing per local EPAs and third-party verification bodies requiring traceable, standards-aligned instrumentation.
• Research-grade flue gas characterization in university combustion labs and national metrology institutes.

FAQ

What is the maximum operating temperature of the heated probe?
The probe is rated for continuous operation at up to +180 °C ambient gas temperature, with active heating maintaining probe tip temperature ≥5 °C above dew point.
Does the instrument support multi-point traverse measurements?
Yes—built-in traverse mode automatically sequences measurement points based on duct diameter and ISO 16911-defined grid patterns, calculating area-weighted average velocity and flow.
Can humidity data be reported as dew point or relative humidity?
Dew point is calculated in real time using measured temperature, pressure, and volumetric humidity; relative humidity is not applicable in hot flue gas applications and is therefore not computed.
Is firmware upgrade supported in the field?
Firmware updates are performed via USB-C connection using signed binary packages verified by embedded cryptographic signature validation.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), including as-found/as-left data for humidity, pressure, and temperature channels.
