Abstract The most commonly used flowmeter in mine air duct detection is differential pressure flowmeter. This paper introduces a del Taba flowmeter for measuring the ventilation performance of the air duct, briefly describes the measurement principle and basic structure of the del Taba flowmeter, and compares and analyzes the ability of different flowmeters in the air duct measurement. At the same time, combined with the application of the del Taba flowmeter in the actual air duct detection, it shows the advantages of the flowmeter in the air duct measurement.
