1. Unit of thermal gas flowmeter
The unit of thermal gas flowmeter mainly depends on the measurement principle and display settings, usually in volume flow units or mass flow units. 1. Absolute flow rate unit • cubic meter/hour (m ³/h): The most commonly used unit of volumetric flow rate, suitable for industrial process control. • liters per minute (L/min): commonly used in small pipelines or laboratory environments. • Standard cubic meter per hour (Nm ³/h): Refers to the volumetric flow rate of gas at standard conditions (0 ° C, 101.325kPa), used for trade settlement and energy consumption measurement
2. Mass flow unit • Kilogram per hour (kg/h): A unit for directly measuring gas mass flow rate, with high accuracy and not affected by temperature and pressure. • Ton/hour (t/h): Used for high flow gas measurement, such as power plant flue gas monitoring
3. Other commonly used units • Foot ³/minute (CFM): British unit, commonly used in ventilation systems in North America. • Gallons per minute (GPM): mainly used for liquid measurement, but some gas flow meters can also switch display
4. Unit conversion and setting - Contemporary thermal flow meters usually support multi unit switching and need to be set in the instrument menu. -If the display unit is SCFM (standard cubic feet per minute) or SLPM (standard liters per minute), it means that it has been automatically compensated to the standard state. -Attention: The volumetric flow rate in non-standard conditions can only be converted to accurate values by compensating with temperature/pressure sensors
5. Selection and usage precautions - For industrial sites, Nm ³/h or kg/h should be preferred to avoid measurement deviation caused by tempe
2. Introduction to Gas Mass Flowmeters
Currently, the gas flow meters used in China have the problem of a small range ratio, and the flow below the lower limit of the range is basically lost. However, this is unacceptable in some fields, especially in gas and other trade settlement situations.
. The hot gas mass flowmeter has successfully solved this problem. 1. Characteristics: 2 Usage: This product is widely used in industries such as steel plants, coking plants, petroleum, chemical, thermal, medical, thermal power plants, and environmental protection. Can be used for: ● Measurement of gas flow rate in steel plants and coking plants ● Measurement of boiler air flow rate and secondary air volume ● Measurement of flue gas flow rate discharged from chimneys ● Measurement of waterfall gas flow rate in water treatment ● Measurement of gas flow rate in cement, cigarette, and glass production facilities ● Measurement of compressed air flow rate ● Measurement of gas flow rate in natural gas, coal gas, liquefied gas, torch gas, hydrogen, and other gases3. What are the technical advantages of thermal gas mass flow meters
True mass flow meters do not require temperature and pressure compensation for gas flow measurement, making measurement convenient and accurate. The mass flow rate or standard volume flow rate of the gas can be obtained. Wide
