Three different level gauge principles and features
First, ultrasonic level gauge
Measuring principle: The liquid level is calculated by measuring the distance from the liquid surface with ultrasonic waves from the opening of the tank top.
Features: It can measure high viscosity liquid and mud without contact with liquid.
1. The pressure vessel cannot be measured;
2. The absorption of ultrasonic waves by the vapor and dust above the liquid surface may not measure the echo;
3. The antenna is immersed in the vapor of the liquid to be tested, and is not suitable for the measurement of self-polymerization, high-purity, flammable, aseptic, corrosion, toxic,high-viscosity liquid.
Safety: It is not safe to measure toxic, corrosion, pressure, and flammable liquids.
Price: low to medium
Second, smart electric float level gauge
Measuring principle: buoyancy principle
Features: measurable interface and liquid level, intelligent.
Disadvantages: Not suitable for measurement of pressure vessels and highly corrosive liquids
Safety: It is not safe to measure pressure, corrosion, toxic, and flammable liquids.
Third, ELL-FI external measuring level gauge
Measuring principle: Using microvibration analysis.
Features: No opening, continuous measurement outside the tank, it is completely non-contact measurement, the pressure inside the container is unlimited, and it can measure flammable, high cleanliness, highly toxic, strong corrosive, explosive, self-polymerization and other media. Easy to install, no need to fire, no need to stop production.
Safety: the safest
