Laser liquid level transmitter is an instrument that uses the principle of laser ranging to measure liquid level. It emits laser pulses and measures the time required for the pulses to travel back and forth. Based on the time difference, the height of the liquid level can be calculated.
Laser level transmitters have the following advantages:
Non contact measurement: The laser liquid level transmitter does not come into contact with the liquid, so it will not contaminate or be corroded by the liquid.
High precision: The measurement accuracy of the laser liquid level transmitter can reach the millimeter level.
Good stability: The laser liquid level transmitter is not affected by environmental factors and has good measurement stability.
Long service life: Laser liquid level transmitters have a long service life and low maintenance costs.
Laser liquid level transmitters are widely used in industries such as petrochemicals, power, metallurgy, and water treatment.
The following are some common laser level transmitters:
ABB LM80
Siemens SITRANS L
Endress+Hauser Prosonic FDU90
VEGA VEGAPULS 69
Application field:
Petrochemical industry: used to measure the liquid level inside containers such as oil tanks, storage tanks, and pipelines.
Electricity: used to measure the liquid level inside equipment such as boilers and steam turbines.
Metallurgy: used to measure the liquid level in equipment such as steelmaking furnaces and blast furnaces.
Water treatment: used to measure the liquid level in containers such as water pools and tanks.
Selection guide:
Measurement range: Select the appropriate measurement range based on the range of the measured liquid level.
Accuracy: Select the appropriate accuracy according to the application requirements.
Output signal: Select the appropriate output signal according to the application requirements.
Protection level: Select the appropriate protection level based on the application environment.
Installation precautions:
The laser liquid level transmitter should be installed in a horizontal position.
The distance between the laser liquid level transmitter and the surface of the measured liquid should be maintained within the specified range.
Laser liquid level transmitters should avoid exposure to strong light.
Maintenance:
Regularly check if the installation of the laser liquid level transmitter is secure.
Regularly clean the lens of the laser level transmitter.
Regularly calibrate the laser liquid level transmitter.
