Radar level gauge analyzes float magnetic pseudo-level gauge based on its working principle
2012-4-11 14:08:34

适用于温度、压力变化大,腐蚀性工况,粉煤灰以及挥发腐蚀性液体等介质的测量。 The radar level gauge is suitable for the measurement of media such as large temperature and pressure changes, corrosive conditions, fly ash and volatile corrosive liquids. According to analysis, the radar level gauge has the following characteristics in measurement: accurate, safe and energy saving-the radar level gauge can measure under vacuum and pressure, and it is accurate, safe, and highly reliable. It can be applied to various occasions without any restrictions. The radar level gauge uses materials that are chemically and mechanically stable, and the materials can be recycled, which is highly environmentally friendly. Maintenance-free and highly operable-the microwave is almost undisturbed and does not come into direct contact with the measurement medium, and can be used in almost all occasions, such as vacuum measurement, level measurement, or level measurement. Due to the use of advanced materials, it is durable against extremely complicated chemical and physical conditions, and it can provide accurate and long-term stable analog or digital level signals. Suppression of interference echoes—for example, interference echoes caused by joints in the beam range and interference echoes caused by incoming or outgoing noise can be automatically suppressed by internal fuzzy logic control. Easy maintenance and simple operation-the radar level gauge has fault alarm and self-diagnosis functions. Analyze the fault according to the error code prompted by the operation display module, and determine the fault in time to eliminate it, making maintenance and calibration more convenient and accurate, and ensuring the normal operation of the instrument. Continuous and accurate measurement-due to the characteristics of electromagnetic waves, it is not affected by the environment. Therefore, its measurement applications are relatively wide. The probe of the radar level gauge has no contact with the surface of the medium, which is a non-contact measurement, which can accurately and quickly measure different media. The probe is hardly affected by temperature, pressure, gas, etc. (the effect is only 0.018% at 500 ° C and 0.8% at 50bar). Wide range of applications, can measure almost all media-from the shape of the tank body, the radar level gauge can measure the liquid level of spherical tanks, horizontal tanks, cylindrical tanks, cylindrical cone tanks, etc. Functionally, it can measure the liquid level in storage tanks, buffer tanks, microwave tubes, bypass pipes; from the measured medium, it can measure liquids, particles, slurry, etc.

测量时,我们应注意:测量范围从波束触及罐低的那一点开始计算,但在特殊情况下,若罐低为凹型或锥形,当物位低于此点时无法进行测量。 In addition, when measuring with a radar level gauge , we should note that the measurement range is calculated from the point where the beam touches the tank low, but in special cases, if the tank low is concave or conical, when the level is below this point Measurement is not possible at this time. If the medium has a low dielectric constant, when the tank is at a low liquid level, the tank can be seen low. At this time, in order to ensure the measurement accuracy, it is recommended to set the zero point at a low height of C. It is theoretically possible to measure the position of the antenna tip, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100 mm from the antenna tip. For overflow protection, a safety distance can be defined to be attached to the dead zone. The minimum measurement range is related to the antenna. Depending on the concentration, the foam can both absorb microwaves and reflect them, but it can be measured under certain conditions. It is understood that the float magnetic level meter is used in conjunction with a liquid level control switch and a liquid level remote transmission and transmission device, which can remotely control and display the liquid level. Then why does it have a false liquid level phenomenon? The radar liquid level gauge analyzes according to its working principle. The reasons for the false level of the float magnetic liquid level meter are as follows: the external interference signal is too large, causing the circuit to get false The signal is not the signal actually measured; the waveguide wire inside the float magnetic level gauge is faulty, such as looseness, poor sealing and water rust, etc., causing signal distortion; the signal processing circuit is faulty; the waveguide wire is incorrectly installed, and the signal transmission is distorted.

就目前市场分析,浮子磁性液位计是使用最广泛的一种液位计,其操作简单,被广泛地应用于电力、石油、化工、冶金、环保、船舶、建筑、食品等行业生产过程中的液位测量与控制。 The radar level gauge is currently on the market analysis. The float magnetic level gauge is the most widely used level gauge. Its simple operation is widely used in power, petroleum, chemical, metallurgy, environmental protection, ships, construction, food, etc. Level measurement and control in industrial production processes. Reliable use is favored by people, so the phenomenon of false liquid level can be ruled out according to the above information! In addition, the float magnetic level gauge has a phenomenon of false liquid level. The radar level gauge thinks that it is related to its working principle. This level gauge generally uses the principle of magnetostriction, and the signal of the magnetic float is transmitted by the waveguide wire. The circuit processes the signal to get the level value
