Laser glass level gauge is a non-contact liquid level measurement solution designed for glass containers. It combines laser ranging technology with the optical characteristics of glass containers and is suitable for accurate monitoring of transparent or semi transparent liquids in fields such as chemical engineering and laboratories. The following provides a detailed explanation from the aspects of technical principles, application scenarios, advantages, and precautions:
Its main features and functions include:
High precision and high reliability: The laser glass level gauge can maintain high precision and reliability in high temperature environments (such as 1480 ℃), with a repeatability of up to ± 0.5mm.
Multiple output modes: Supports programmable analog 4-20mA output (three wire system), and can directly provide liquid level signals to the display controller through RS232/422 serial port.
Widely used: Suitable for various industrial application scenarios such as glass flow channel liquid level detection, melting furnace glass liquid level detection, and high-temperature glass product width and thickness dimension detection.
Precautions for use
Cleaning and maintenance: Regularly wipe the glass surface to prevent dust or condensed water from interfering with the laser.
Calibration cycle: Calibrate every 6-12 months (depending on the stability of the medium).
Electromagnetic interference: Avoid strong magnetic field environments (such as near frequency converters), and if necessary, choose fiber optic transmission type.
Installation position: Avoid the feeding port or mixer to reduce the impact of liquid level fluctuations.
Laser glass level gauges solve the limitations of traditional float or capacitive level gauges in glass containers, such as corrosion and adhesion issues, through non-contact and high-precision measurement. When selecting, it is necessary to consider the characteristics of the medium (temperature, corrosiveness), container shape (cylindrical/spherical), and environmental interference factors, and choose a model with multiple reflection suppression and refraction compensation functions. For complex working conditions, it is recommended to optimize performance through simulation testing or on-site debugging provided by the manufacturer.
