KGD - WQ - 526 Vehicle Exhaust Flow Analyzer
Product Introduction
The KGD - WQ - 526 Vehicle Exhaust Flow Analyzer uses the ultrasonic and vortex street principles to measure the flow rate of diluted motor vehicle exhaust, and employs a zirconia sensor to measure the concentration of the diluted gas. It is one of the core components of the VMAS system. It is used to measure the flow rate, pressure, temperature, and diluted oxygen concentration of the exhaust gas emitted by gasoline engines of motor vehicles. It complies with the requirements of the national standard GB 18285 - 2018 "Limits and Measurement Methods for Emissions from Gasoline - fueled Vehicles (Double - Idle Speed Method and Simple Driving Cycle Method.
