1. Thermal mass flowmeter and differential pressure flowmeter

The main differences between thermal mass flowmeter and differential pressure flowmeter are as follows: range and selection: Thermal mass flowmeter has a wider range of applications, covering pressure ranges from vacuum to 100 bar, which enables it to perform well in multiple operating conditions. Differential pressure flowmeter: typically operates between atmospheric pressure and 10 bar, with a relatively narrow range of measurement. Physical performance: Thermal mass flowmeter: Its internal structure is based on generating predictable and repeatable flow diversion between laminar flow elements (LFE) and bypass sensors. The better the working effect of laminar flow components, the more accurate the prediction of gas flow rate and the more accurate the flow diversion, thus ensuring the high performance of the flowmeter. In addition, due to the mechanical size based diversion of the thermal bypass instrument, absolute temperature and pressure do not actually affect the diversion, making its readings more stable. Differential pressure flowmeter: Its reading is directly affected by the viscosity in LFE, which is greatly affected by temperature and pressure. This may result in the instrument being highly sensitive to small changes in flow rate, thereby affecting its accuracy and stability. Accuracy: Thermal mass flowmeter: Its total operational accuracy depends only on one sensor (measuring direct thermal mass flow), so there are fewer sources of error. This design enables the thermal mass flow meter to maintain high accuracy during the measurement process. Differential pressure flowmeter: Multiple sensors are required to calculate the mass flow rate ba

sed on the measured volume flow rate, temperature, and pressure. This design increases the possibility of error superposition, thereby affecting its overall accuracy. Specifically, differential pressure flow meters require measuring the temperature at two locations to compensate for temperature errors, which increases the complexity and uncertainty of the measurement. Complexity and maintenance: Thermal mass flowmeter: Due to its relatively simple structure, it requires fewer sensors, making maintenance and calibration relatively easy. This reduces the cost of use and improves the reliability of the equipment. Differential pressure flowmeter: Due to its relatively complex internal design and basic principles, it requires more sensors and measurement systems to achieve the same goals. This increases the complexity and maintenance costs of the equipment, while also potentially reducing its reliability. Applicable scenarios: Thermal mass flowmeter: Due to its wide range, high accuracy, good stability, and easy maintenance, it is suitable for flow measurement under various working conditions, especially in situations where high-precision measurement is required. Differential pressure flowmeter: Although its accuracy and stability may be slightly inferior to thermal mass flowmeter, it still has certain application value in certain specific situations (such as situations with small pressure range and low precision requirements). Image display: In summary, both thermal mass flow meters and differential pressure flow meters have their own advantages and disadvantages. The choice of which type of flow meter to use depends on the specific application scenario and requirements. In situations where high precision, wide range, and st
