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. What are the common units of measurement for gas flow meters

1. L/min: liters per minute, used to represent the flow rate of fluids

2. ml/min: milliliters per minute, used to represent the flow rate of small volume fluids

3. L/h: liters per hour, used to represent the flow rate of fluids over a certain period of time

4. m ³/h: cubic meters per hour, used to represent the flow rate of larger volume fluids

5. Nm ³/h: cubic nanometers per hour, which is a very small flow unit, usually used for special scientific research or Industrial Applications

6. T/H: Tonnage per hour, used to represent the flow rate of fluid mass

7. Liters per minute. Hail transportation: Liters per minute, the same as L/min, used to represent the flow rate of fluid

8 L/h: The number of liters per hour, similar to L/h, used to indicate the flow rate of fluid in the sail room at a certain time. 9. Cubes per hour: The number of cubes per hour used to represent the flow rate of a fluid, typically used for large-scale fluid measurement. 10. Ton/H: The hourly tonnage, similar to T/H, used to represent the flow rate of fluid mass.

3. What is the difference between sccm and ccm in the units read by gas mass flow meters? CCM represents a gas flow rate of 1 cubic centimeter per minute, which is equivalent to cubic centimeters per minute (㎤/m
