product overview

ZEF-GDL204QC flue gasUltrasonic flow ratecountDivided into integrated flue gasUltrasonic flow rateCalculation and injection type flue gasUltrasonic flow rateCalculate.Domestic independent research and development to solve all the difficulties in measuring flue gas flow, such as low wind speed, high accuracy, high humidity, and blockage prevention.Airflow passing through ultrasonic transducer probevelocity variationgeneratetime difference，Ultrasonic flowmeter utilizing the principle of time difference measurement.onebodyThe ultrasonic flowmeter for flue gas is easy to install, cost-effective, capable of measuring flow at a single point in the flow field, has poor relative accuracy, and operates in noisy environments,Jet type flue gasUltrasonic flow ratecountInstallation is relatively difficult, the product value is high, the entire cross-section of the flow field is measured, and the accuracy is high.flue gasUltrasonic flow ratecountCompared to the traditional differential pressure principle, the application of measuring emissions in the environmental protection industryFlow meters such as pitot tubes, multi-point matrices, and Venturi tubes have advantages such as low flow rate measurability, wide range ratio, resistance to blockage, and easy installation；flue gasUltrasonic flow rateCalculation andCompared to thermal flow metersIt has the advantages of not being afraid of temperature changes and being afraid of two-phase flow of steam and water.
