1. How to measure the quality of a thermal gas mass flowmeter?

A thermal gas mass flowmeter can be comprehensively judged for its quality through appearance inspection, power testing, flow comparison, signal detection, zero point inspection, and professional calibration.. 1. Appearance inspection: Firstly, observe whether the flowmeter housing is damaged or deformed, check whether the connection parts are loose, and whether the wires are broken or worn. Obvious physical damage often indicates that internal components may be damaged, which can affect measurement accuracy. 2. After connecting the power supply, pay attention to whether the instrument display is clear and stable, whether there are garbled characters or no display at all. Abnormal power supply usually points to power supply issues or internal faults in the instrument, which is the basis for determining whether the equipment is working properly. Flow testing comparison: Install the flowmeter in a stable gas circuit, introduce gas with a known flow rate, and compare the displayed value with the actual value. If the error continues to exceed the accuracy range indicated on the pro

duct label, it is likely that there is aging or damage to the measuring components. 4. Signal output inspection: Check whether the analog signal (such as 4-20mA) or digital output is stable and in line with flow changes through detection equipment. Abnormal or out of range signal fluctuations often indicate sensor or signal processing module faults. 5. Zero point check: When the gas is completely stationary, observe whether the displayed value returns to zero. If there is a significant deviation, it may be zero drift, and the sensor status needs to be calibrated or further checked. 6. Professional instrument testing uses high-precision calibration devices for testing, which can comprehensively evaluate the performance indicators of the flowmeter. Professional calibration can clearly determine whether it meets industry standards and is suitable for scenarios with high precision requirements.
