1. Measurement range of DN80 gas vortex flowmeter
The measurement range of DN80 gas vortex flowmeter does not have a unified fixed value, and may vary greatly depending on the product model and usage conditions (gas distribution type, temperature and pressure). The common reference range is as follows
1. Conventional mainstream product parameter range - gas flow rate range: generally 5m/s~50m/s - corresponding volume flow rate range: about 100m ³/h~1000m ³/h. 2. Some niche/customized product parameter ranges. The gas flow rate range of some products is 4m/s~35m/s. Selection precautions: When selecting and using, please be sure to refer to the official manual and technical parameter table of the corresponding product.
2. Selection and specification of steam flow meter
The selection and specification of steam flow meter should consider the following points: diameter: DN25: suitable for liquid flow range of 1-10m3/h to 60m3/h, gas flow range of 25m3/h to 60m3/h. DN32 and DN40: The flow range varies depending on the type of liquid and gas. DN50 to DN200: The flow range gradually expands to accommodate a wider range of liquid and gas flow rates. DN300 and above: It is recommended to use a plug-in flowmeter. Temperature and pressure compensation function: N: No compensation function. Y: There is a compensation function. Output model: F1: Two wire system 420mA. F2: Three wire system 420mA. F3: RS485 communication interface. Type of tested medium: J1: liquid. J2: Gas. J3: Steam.

3. Understanding the caliber of thermal gas mass flow meters: Choosing the correct size to ensure accurate measurement
The selection of the caliber of thermal gas mass flow meters should be based on flow range, flow rate, accuracy requirements, and application pressure drop. Thermal gas mass flow meters are a key flow measurement device, and the choice of caliber is crucial for ensuring accurate gas flow measurement.. The following will discuss in detail the importance of the diameter of a thermal gas mass flowmeter and how to choose the appropriate size.
1. Definition of Diameter of Thermal Gas Mass Flow Meter The diameter of a thermal gas mass flow meter refers to the internal channel diameter or cross-sectional area of the flow meter, usually measured in inches (inches) or millimeters (millimeters).
. The size of the aperture directly affects the measurement range and sensitivity of the flowmeter, and is one of the key factors to consider when choosing a flowmeter.Second, the principle of selecting caliber: Flow range requirements: Choose the caliber based on the expected gas flow range in the application.
. Larger caliber flow meters are typically suitable for high flow applications, capable of handling larger gas flows without easily clogging or generating excessive pressure drop. Smaller caliber flow meters are suitable for low flow applications and can provide higher measurement accuracy and
