1. Introduction to Target Flow Meter

Target flow meters have been applied in industrial flow measurement since the 1960s, mainly used to solve the flow measurement of high viscosity and low Reynolds number fluids. They have gone through two stages of development: pneumatic meters and electric meters. The SBL series intelligent target flow meter is a new type of flow meter developed based on the measurement principle of the original strain gauge (capacitive) target flow meter, using the latest force sensing sensor as the measurement and sensitive transmission element, and utilizing contemporary digital intelligent processing technology.

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 relationship between displacement and flow velocity.

. Detailed explanation: Fluid force: The core component of a target flowmeter is a target plate. When a fluid (gas or liquid) passes through the flowmeter, it will generate a force proportional to the flow velocity on the target plate. This force will cause slight displacement of the target plate. The relationship between displacement and flow velocity: There exists a definite mathematical relationship between the displacement of the target plate and the flow velocity of the fluid. By measuring the displacement of the target plate, the flow velocity of the fluid can be indirectly measured. Flow calculation: After knowing the flow rate, combined with parameters such as the cross-sectional area Image of target flowmeter

of the flowmeter, the flow rate of the fluid can be calculated using a flow formula (such as Q=Av, where Q is the flow rate, A is the cross-sectional area, and v is the flow rate). The working characteristics of the target flowmeter are: sturdy structure: the entire instrument structure is sturdy, without movable parts, and the plug-in structure makes disassembly easy, maintenance and replacement convenient. Diverse materials: Various anti-corrosion and high/low temperature resistant materials can be selected, such as Hastelloy, titanium, etc., to meet the needs of different fluid media and working environments. High pressure sealing: The whole machine can be made fully sealed without dead corners (welded form), without any leakage points, and can withstand high pressure up to 42MPa, ensuring the accuracy and safety of measurement results. Self check program: The instrument is equipped with a self check program, which makes it easy to identify and solve problems in a timely manner when a fault occurs. Safe and reliable: The sensor does not come into contact with the measured medium, and there is no problem of component wear. It is safe and reliable to use, which extends the service life of the flowmeter. Wide measurement range: It can accurately measure gas and liquid flow rates under various normal temperature, high temperature (up to 500 degrees), and low temperature (-200 degrees) working conditions, with a wide range of applications. Picture display: This picture shows the structure and working principle of the target flowmeter. Through this picture, we can more intuitively understand how the target flowmeter calculates flow by measuring the displacement of the target plate.
