1. What are the requirements for installing a flowmeter on the main steam outlet pipeline of a steam boiler? When installing a flowmeter on the main steam outlet pipeline of a steam boiler, it is important to pay attention to factors such as pipeline conditions, steam characteristics, installation location, and match corresponding supporting facilities. The core requirements can be summarized as follows:

1. Pipeline conditions • Straight pipe section requirements: A straight pipe section with a diameter of 10-50 times should be reserved upstream of the flowmeter, and a diameter of 3-10 times should be reserved downstream.

. If the pipeline cannot meet the requirements, it is necessary to adjust the flow state through a rectifier to ensure stable steam flow. • Pipe diameter matching: If the flow meter does not match the diameter of the pipeline, a tapered or expanding pipe should be used for transition. After installation, pressure testing should be conducted to confirm the sealing and prevent leakage.

2. Steam characteristic adaptation • Temperature and pressure: Flow meters made of high-temperature and high-pressure resistant materials such as 316L stainless steel should be preferred, such as vortex street and differential pressure flow meters. It is recommended that the long-term operating temperature be lower than 80% of the design value. • Dryness control: For wet steam (dryness below 95%), a steam water separator should be installed at the inlet of the flow meter, or a dual parameter instrument with temperature and pressure compensation should be used to correct the measurement value. • Anti water accumulation design: When installing horizontal pipelines, the flow meter should be located at the to

p of the pipeline at a 15 ° -45 ° inclined section, with a matching drain valve for regular drainage.

4. Electrical safety protection • Grounding treatment: The grounding resistance should be less than 4 Ω, the cross-sectional area of the grounding wire should not be less than 2.5mm ², and it should be independently separated from the grounding system of the electrical cabinet. • Signal anti-interference: The signal is transmitted using twisted pair shielded cables, and the shielding layer needs to be grounded at one end. The distance between the signal line and the power cable should be kept at least 30cm.

5. The supporting system is complete. • Pre filter: A Y-shaped filter with a mesh of not less than 80 is selected, and the installation position is within 5 times the diameter of the flowmeter inlet, with the discharge outlet facing downwards for cleaning impurities. • Maintenance isolation measures: Install globe valves before and after the flowmeter, and connect them to the bypass pipeline. It is recommended to use gate valves for bypass valves to reduce pressure loss.

2. What is your understanding of automotive air flow meters? Air flow meter, also known as gas air flow meter, is an indispensable part of electronic fuel injection engine. It converts the incoming cyclone into an electronic signal and sends it to the electronic device control module (ECU), which serves as a sensor to accurately measure the cyclone entering the car engine and is one of the basic data signals for determining the ignition advance angle. With the application of microcomputer controlled gasoline and diesel fuel injection, several other types of gas air flow meters have emerged, such as gate valve gas air flow meters an
