What are the types of level gauges?

There are many types: differential pressure type, float type, radar type, ultrasonic type, air-blown type, electric contact type, magnetic flap type

Try to search for such topics on Baidu. If you want to provide support, you can actually find valuable samples, technologies, and other materials from reputable organizations. Or rather, what industry one is in, one’s current situation, what one needs, and so on.

That’s too general; what about the measurement method?

There are too many things I don’t want to say; you can just search for such topics on Baidu

There are too many varieties, and different working conditions require different choices. . :)

Suitable for the most demanding environments—capable of measuring liquids with any pressure, extreme toxicity, high corrosivity, absolute sterility, or extremely high purity, as well as those with known sound speeds. 2. Safe—when measuring toxic, corrosive, pressurized, flammable, explosive, volatile, or leaky liquids, since both the sensing element and the instrument are located outside the container, there is no contact with the liquids and gases inside the tank during installation, repair, or maintenance, making it very safe. Even when the instrument is damaged or under maintenance, there is absolutely no possibility of leakage. 3. Environmentally friendly – It features true isolation measurement, with no contact at all with the medium being measured; there is no possibility of liquid or gas leakage, and it does not contaminate the environment, making it a truly green and environmentally friendly instrument. 4. Convenience and cost-effectiveness — Online maintenance can be carried out without shutting down production. Since there is no need to make holes in the container, nor are flanges or connection pipes required, installation and maintenance are extremely convenient and cost-effective. 5. Durable and reliable—The measuring head and instrument contain no mechanical moving parts, and are tightly sealed to isolate them from the outside environment; as a result, they do not wear out or corrode, making them highly durable and reliable with minimal maintenance required. 6. Precision: It features temperature compensation and continuous automatic calibration to ensure the highest measurement accuracy at all times. The precision is 1 millimeter, with a maximum range of 3 meters. It can be used properly and provide accurate measurements even in different temperatures as well as on moving vehicles and ships. 7. It features an LCD display and is easy to use; simply apply coupling agent to the probe, press it firmly directly below the container, and wait until the echo is appropriate.
