Advantages of ultrasonic externally mounted liquid level switch

What are the advantages of ultrasonic externally attached liquid level switches? Ultrasonic external stick liquid level switch is a non-contact liquid level detection instrument using ultrasonic detection technology. With special probe design and non-immersion detection, it is especially suitable for applications with hygienic requirements, high pressure, radioactivity, toxicity, corrosion and other special occasions. Its simple installation method and high protection level ensure that the whole machine can work in harsh environments for a long time. The instrument is easy to adjust and easy to operate. It is a very easy-to-use instrument. In the past, when using the ultrasonic principle to measure the liquid level in the container, the ultrasonic residual vibration signal in the container wall is often regarded as a disadvantageous factor, because it will increase the measurement blind area, especially when the plate of the container wall is thicker , When the echo signal is weak, the residual vibration signal has a greater impact on the blind area. Trying to suppress the effects of after-vibration signals can be laborious. After years of research and experimentation, it is found that the attenuation characteristics of the ultrasonic residual vibration signal in the container wall are closely related to the liquid level of the container. Using this rule, the ultrasonic externally attached liquid level switch can easily realize the ultrasonic non-intrusive fixed-point liquid level detection. Compared with other non-intrusive fixed-point liquid level detection methods, this method has very significant advantages. The advantages of the ultrasonic externally attached liquid level switch are also reflected in the following four aspects: 1. Easy installation: during installation and maintenance, it does not fire, and the tank is not clear, which does not affect production. 2. Reliable and durable: There are no mechanical moving parts in the sensor and instrument, and they are strictly sealed, isolated from the outside world, and will not wear or corrode. 3. Widely used: it has nothing to do with the pressure, temperature, density, dielectric constant, viscosity and corrosiveness of the measured medium. 4. High safety: when measuring toxic, corrosive, pressurized, flammable, explosive, volatile, and leaky liquids, no valves, connecting pipes, joints, no leakage points, and no contact with the liquid and gas in the tank are used.
