Product Details
Thermal mass flowmeterThermal Mass Flow Meter is an instrument used to measure gas mass flow rate, mainly based on the principle of heat transfer. It determines the mass flow rate of gas by detecting changes in thermal conduction during gas flow, and is suitable for precise measurement of various gas flow rates.Thermal mass flowmeterHas the following main characteristics:
Principle:Thermal mass flowmeterMeasure the thermal conductivity characteristics of fluids through heating sensors. When gas passes through a sensor, it takes away a certain amount of heat. The higher the gas flow rate, the more heat it takes away, and the sensor will detect this change. Based on the relationship between heat loss and gas flow rate, a flow meter can calculate the mass flow rate of gas.
Applicability:Thermal mass flowmeterVery suitable for measuring gas flow, especially when not affected by changes in gas temperature and pressure. Common applications include flow measurement of industrial gases such as air, nitrogen, oxygen, argon, etc.
Thermal mass flowmeterAdvantages:
No pressure compensation required:Thermal mass flowmeterDirectly measuring the mass flow rate of gas is not affected by gas temperature and pressure fluctuations, avoiding the complexity of requiring additional pressure or temperature compensation.
Fast response time:Thermal mass flowmeterFast response speed, able to quickly reflect changes in gas flow rate.
No movable parts: Usually there are no mechanical parts, so maintenance is simple and reliability is high.
Suitable for low flow range: Thermal flow meters are suitable for measuring gases with lower flow rates, and are not as effective as other types of flow meters for measuring gases with higher flow rates.
In short,Thermal mass flowmeterWidely used in gas flow monitoring and control, especially in applications that require high precision, such as chemical engineering, environmental monitoring, laboratory research, and other fields.
