3. When adjusting the flow meter for atomization, there is no unified fixed value for the adjustment value of the flow meter matched with the atomization system. It needs to be matched with the type of atomization medium, nozzle specifications, target delayed detection lead atomization effect and working pressure. The common adjustment range is: gas medium flow meter 0.2~10 m ³/h, liquid medium flow meter 0.01~2 L/min.

1. Typical adjustment parameters for different media (1) Gas atomization scenario (such as compressed air assisted atomization) 1 Micro precision atomizing nozzle for laboratory and small-scale spraying: adjust the rotor flow meter to 0.2~2 m ³/h, and with a supply pressure of 0.2~0.4 MPa, it can generate fine mist with a particle size of 10~50 μ m; 2. Industrial level large flow atomization (dust reduction, cooling): adjust the vortex street/mass flowmeter to 3~10 m ³/h, cooperate with 0.5~0.8 MPa air supply pressure, and cover the range of 10~50 ㎡ spray. （2） Liquid atomization scene (such as water and drug atomization) 1 Laboratory small atomization device: equipped with a gear flowmeter adjusted to 0.01~0.1 L/min, it can achieve micrometer level uniform mist droplets, suitable for drug aerosol and small humidification scenarios; 2. Industrial spraying or humidification spray gun: Adjust the unperforated turbine flow meter to 0.1~2 L/min, with a supply pressure of 0.3~0.6 MPa, to match the flow requirements of conventional pneumatic spray guns.

2. Key points for adjustment and verification 1 First, confirm that the range of th

e flowmeter matches the rated flow rate of the nozzle. It is strictly prohibited to operate beyond the range and cause measurement errors to be amplified; 2. The flow rate and atomization pressure need to be adjusted in conjunction. When the pressure increases, the flow rate should be appropriately reduced to avoid excessive droplet size or strong jet flow; When dealing with corrosive and high viscosity media, it is necessary to refer to the flowmeter parameter table after viscosity correction of the medium for adjustment, and cannot directly apply the general range. 3. For atomization systems involving high-pressure gases, high temperatures, or corrosive media, the parameters must be adjusted by personnel with corresponding special equipment operation qualifications to avoid safety risks such as overpressure leakage and medium splashing.

4. What are the development trends of the thermal mass flowmeter industry in 2026?

The core development trends of the thermal mass flowmeter industry in 2026 can be predicted in advance from the current industry trends, mainly focusing on four directions: technology, scenarios, demand, and competition.
