Three different level gauge principles and features

Last Update Time: 2019-06-12 14:48:45

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.

 

Disadvantages:

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.

Price: high

 

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

 

Price: Medium
