1. What are the commonly used models of low-pressure and high flow air flow meters? The commonly used low-pressure and high flow air flow meters mainly include thermal gas mass flow meters, Annubar/Velbar flow meters, LWQ series compressed air flow meters, and universal vortex flow meters.

1. Thermal gas mass flowmeter 1 Adaptation scenario: Suitable for low-pressure air metering with low flow rate, wide range, and large diameter, it can directly measure mass flow rate without additional temperature and pressure compensation, and has high sensitivity to low flow rate gases. Performance parameters: accuracy of ± 1.0% to ± 1.5% FS, diameter coverage of DN15 to DN2000, and plug-in models can be adapted to ultra large diameter pipelines for infiltration.

2. Anuba/Veliba flowmeter 1 Installation features: Plug in installation does not require pipe breakage, with minimal pressure loss, suitable for measuring large-diameter air ducts, such as factory ventilation and large fan supply scenarios. Advantages and limitations: The pointer type can be read directly on site, with a simple structure and resistance to temperature and visible car spine pressure, suitable for low budget routine monitoring. However, under conditions containing impurities, it is easy to cause blockage of throttling components and needs to be cleaned regularly.

III. LWQ Series Compressed Air Flow Meter 1. Standard Basis: Developed in accordance with GB/T32021-2015 standard, integrated with temperature, pressure, flow sensors and intelligent flow integrator

2. Performance Features: Excellent low-pressure and high-pressure metering performance, flow range ratio of 20:1, good repeatability, accuracy up to 1.0 level, low pressure lo

ss, low initial flow rate

3. Model Example: LWQ-25, nominal diameter DN25, starting flow rate ≤ 0.8m ³/h, flow range 2.5-25m ³/h.

4. Universal Vortex Flow Meter 1 Adaptation scenario: Suitable for low-pressure air metering scenarios with medium to high flow rates, stable flow rates, and relatively stable pipeline pressures. Performance features: no moving parts, low pressure loss, long service life, with temperature and pressure compensation, accuracy of ± 1.0% R, caliber range of DN15 to DN300. Model example: such as Duoqin DVS-DG15F11U, medium is air, DN15 caliber, body material is 304 stainless steel, working pressure is 1.6MPa, can display instantaneous and cumulative flow on site, supports 4-20mA output, 24V power supply, and ensures flow measurement range of 2.8-12m ³/h for sail accuracy.

2. What does the scfm on the flowmeter mean? The SCFM on the flowmeter refers to standard cubic feet per minute. It is a unit of measurement used to represent gas flow rate. It is very common in various applications, especially in compressed air and gaseous fuels. Here is a detailed explanation: Firstly, a flowmeter is a device used to measure fluid flow. It can perform continuous or periodic flow measurement in industrial production processes. Among them, SCFM is a unit in flow measurement used to indicate the flow rate of gas. SCFM represents the volume of gas flowing through a certain point during a specific time period, which is crucial for understanding the gas consumption and production process control of the system. Secondly, the "standard cubic foot" in SCFM refers to a unit of measurement for volume under specific conditions. The standard conditions here usually refer to temperature and pressure.
