What is the difference between the standard diameter DN3 and nominal diameter 4mm for flow meters? DN3 and nominal diameter 4mm refer to the same thing, only in different ways. DN is the abbreviation for the French standard "Non descriptor", also known as the European standard size (DIN, Deutsches Institut f ü r Normung). The DN standard is a system based on nominal diameter, used for the size design of pipeline systems and fittings. DN3 indicates that the nominal diameter of the flowmeter is 3 millimeters. The nominal diameter of 4mm is expressed in metric units, indicating that the diameter of the flowmeter is 4 millimeters. Therefore, both DN3 and nominal diameter 4mm refer to the caliber size of the flowmeter, but they are expressed in different ways. Of course, in practical applications, selecting a suitable flowmeter also requires comprehensive consideration of factors such as the specific requirements of the application and the performance parameters of the flowmeter.

2. What are the models of flow meters for low-pressure and high flow air measurement?

Flow meters that can be used for low-pressure and high flow air measurement mainly include LWQ series, V10FD-L type, Songye Bian LUGB type, P100-PLG type, etc.

1. LWQ series compressed air flow meters. The spine finger series includes multiple products that are suitable for low-pressure air measurement. Among them, Guangzhou Dongyi Automation Technology Co., Ltd.s universal integrated temperature, pressure, flow sensors and intelligent flow integrator have the characteristics of wide flow range ratio (Qmin/Qmax=20:1), 1.0 level measurement accuracy, low pressure loss, low starting flow rate, and sensitivity to fluid disturbance. Low, support

2. The V10FD-L low-pressure field defect type MFC/MFM product from Beijing Sersus Instrument Technology Co., Ltd. is suitable for non corrosive gases below 1MPa. The measurement range covers 5SCCM-250SLM and is divided into three levels: small range (5SCCM-10SLM), medium range (10SLM~30SLM), and large range (30SLM~250SLM). It adopts the principle of differential pressure mass flow measurement without thermal drift and response lag, with a response speed of 100ms and no need for preheating. It supports digital analog compatibility and can communicate with a computer through analog secondary meters, PLC or digital interfaces to complete parameter setting and flow display.

III. LUGB type compressed air flowmeter is a product of Jiangsu Xianda Instrument Co., Ltd., which supports multiple calibers such as DN12

5, DN150, DN200, etc. Different calibers correspond to different flow ranges, and functional codes such as temperature and pressure compensation, output signals, and connection methods can be selected as needed to adapt to low-pressure and high flow air measurement scenarios of different specifications.
