1. Why is the HKB capacitive target flow meter preferred for gas flow measurement? The HKB capacitive target flow fiber meter is mainly based on its unique adaptability and technical advantages in complex gas media. The specific reasons are as follows:

1. Resistance to dirt and blockage. Low sensitivity to impurities: Gas often contains impurities such as ash, tar, water, etc., which are easy to adhere to instrument components. The HKB capacitive target flowmeter adopts a third-generation chip level force sensor, without throttling elements and movable parts, with significant anti impurity and anti dirt characteristics, which can effectively avoid blockage problems. Adapt to low flow rates and complex media: Gas transportation requires control of safe flow rates, typically below 5m/s. This flowmeter directly measures the kinetic energy of the medium through the principle of force induction, with low requirements for the lower limit of flow velocity (up to 0.08m/s), and is not affected by changes in medium density and viscosity. It is suitable for complex gas media such as dust and tar.

2. Structural Design and Performance Advantages High Stability and Long Life: The sensor does not come into contact with the medium, has no worn parts, and is equipped with a fully sealed welding process (pressure resistance up to 42MPa). It can be used for a long time in high temperature (500 ℃) or low temperature (-200 ℃) environments, with high stability.

. Small pressure loss: Its pressure loss is only half of that of a standard orifice flowmeter, which can reduce energy loss, especially suitable for low-pressure gas transportation scenarios. 3. Easy installation and maintenance. Flexible installation method: Kaishi supports online plug-in installation, which can complete construction without stopping the pipeline, reducing installation costs and production losses. Maintenance free design: No movable parts and anti vibration and anti-interference, no need for frequent disassembly, cleaning or calibration, saving maintenance costs. 4. Measurement accuracy and safety High precision output: Microelectronics technology is used to compensate for nonlinear errors, with an accuracy of ± 0.2% and a repeatability error of ≤ 0.1%, meeting the requirements of industrial metrology. Intrinsic safety explosion-proof: The fully sealed structure combined with explosion-proof certification (such as ExdIICT4) complies with safety regulations for gas flammable and explosive places.

Fifth, Typical Application Scenarios: Large diameter gas pipelines: Support measurement of pipe diameters above DN500mm to meet the coarse pipe diameter requirements of gas stations.

. Complicated gas types: including coke oven gas, blast furnace gas, generator gas and other dusty and tar containing media. In summary, the HKB capacitive target flowmeter has become the preferred solution for gas flow measurement due to its anti fouling, low flow rate sensitivity, maintenance free, and high-precision characteristics, especially suitable for complex gas media in industrial scenarios such as metallurgy and chemical engineering.

2. Working principle of target flowmeter

Working principle of target flowmeter: When the fluid flows, it will generate a force on the target plate, causing a small displacement of the target plate. The displacement size is related to the flow velocity, and the flow rate can be calculated based on the mountain resistance relation
