1. Is the measurement of gas by a rotary flowmeter greatly affected by the ambient pressure?

When manufacturing and displaying a rotary flowmeter, there are two types of display: square grinding chamber potato type, one is the working condition and the other is the standard condition.. Operating condition: refers to the flow rate under working conditions, measured in m3/h; Standard condition: A flow rate of around 20 degrees Celsius at a standard atmospheric pressure. If the flow rate in the working state is different from the flow rate under standard conditions, the reading of the flowmeter needs to be converted:

2. How to determine the flow rate from the reading of a regular rotor flowmeter

When using a rotor flowmeter, the data read usually represents instantaneous flow rate, which can be volumetric flow rate or mass flow rate. If the reading is mass flow rate, then it first needs to be converted to volumetric flow rate in m3/s. Next, based on the diameter of the rotor flowmeter, the flow velocity can be estimated by dividing the volumetric flow rate by the cross-sectional area. It should be emphasized here that due to the non-linear relationship of cross-sectional area, the obtained result is only an estimated value. If more accurate data is needed, it is recommended to directly contact the manufacturer for accurate information. The specific steps for operation are as follows: First, confirm whether the flow rate you are measuring is mass flow rate. If not, it needs to be converted through density to obtain volumetric flow rate. Then, based on the diameter of the rotor flowmeter, calculate the corresponding cross-sectional area. Finally, divide the volumetric flow rate by the cross-secti

onal area to obtain the flow velocity. It is worth noting that due to the non-linear relationship between the cross-sectional area of the rotor flowmeter, the result obtained by this method is only an estimated value. If accurate data is required, it is recommended to contact the manufacturer for further confirmation. For example, if you measure a mass flow rate of 100kg/h and a density of 1kg/L, first convert it to a volumetric flow rate, which is 100kg/h ÷ 1kg/L=100L/h. Assuming the diameter of the rotor flowmeter is 25mm, the cross-sectional area is approximately 0.485e-3m2. Finally, the volumetric flow rate is converted to m3/s, which is 100L/h ÷ 3600s=0.027778m3/h, and then divided by the cross-sectional area to obtain a flow velocity of approximately 56m/s. However, please note that this result is for reference only and there may be deviations in actual situations. It is recommended to contact the manufacturer for more accurate data. In summary, the method of obtaining flow velocity through the reading of a rotor flowmeter requires conversion between mass flow rate and volume flow rate, as well as calculation of cross-sectional area based on the diameter of the rotor flowmeter. Although this method can provide a rough estimate, for applications that require high accuracy, it is recommended to directly contact the manufacturer to obtain accurate data. I hope the above information is helpful to you. It should be noted that as a commonly used flow measurement tool, the working principle of the rotor flowmeter is based on the buoyancy of the float in the fluid and the balance of fluid dynamics. Therefore, it is necessary to ensure the correct installation and maintenance of the flowmeter during use. In addition, differ
