Overview of Common Level Gauge Measurement Principles and Types

2026-05-11

Proper selection and regular maintenance are essential for ensuring the measurement accuracy of level gauges.

Classification by Operating Principle

Direct-reading: Utilizes the principle of communicating vessels to allow direct observation of the liquid level through a transparent window

Buoyancy-Type: A float rises and falls with the liquid level, driving an indicator mechanism to display the height

Pressure-Type: Measures the static pressure generated by the liquid column and converts it into a liquid level value

Ultrasonic-Type: Emits sound waves and receives echoes, calculating the liquid level based on the propagation time

Electromagnetic-Type: Utilizes the principle of radar wave reflection; suitable for high-temperature, high-pressure, or corrosive media

 

Common Types and Application Features

Glass Tube/Panel Level Gauges: Simple structure, local display, suitable for normal temperature and pressure conditions

Magnetic Flip-Plate Level Gauges: Red and white dual-color display, can be equipped with remote transmission modules

Ultrasonic Level Gauges: Non-contact measurement, suitable for viscous or corrosive liquids

Radar Level Gauges: Stable measurement, less affected by medium characteristics

Understanding the basic principles of various level gauges helps in making preliminary selection decisions based on on-site conditions.
