Ultrasonic level meter is a kind of liquid level instrument by calculating the ultrasonic emission and reception time difference to determine the height of the liquid level, is a representative of non-contact measurement, this period of time, we have received a number of inquiries, asked the ultrasonic level meter does not have a return wave, resulting in the inability to measure the situation, in response to this problem, we come to you today to unify to make an answer.
Probe Surface Adhesion:
Problem: Dust, oil, media residue, etc. adheres to the probe and impedes ultrasonic emission.
Solution: Clean the probe surface regularly to ensure that the probe is clean and free of dirt.
Gas-phase medium concentration:
Problem: The gas-phase medium concentration is too large, resulting in increased loss during ultrasonic propagation.
Solution: Control the gas phase content of the medium and reduce the amount of water vapor, soot, etc. generated.
Liquid Surface Foam:
Problem: Foam causes ultrasonic waves to be reflected in all directions, resulting in insufficient or unreceivable echoes.
Solution: Consider using an ultrasonic level meter with good foam suppression capability or install a foam suppression device.
Installation position and angle:
Problem: The installation position is too close to the vessel wall or not perpendicular to the measured liquid surface, increasing the measurement blind zone.
Solution: Make accurate measurements and calculations before installation to ensure that the installation position and angle are appropriate.
Occluded objects in front of the probe:
Problem: Occluded objects in front of the probe produce error echoes.
Solution: Ensure that there is no obstruction in front of the probe, and check the surrounding environment regularly to avoid obstruction at a later stage.
Ultrasonic level meter parameter settings:
Problem: Improper parameter settings, such as ultrasonic frequency, transmit power, etc..
Solution: Adjust the parameter settings of the ultrasonic level meter according to the actual application scenario.
Hardware failure:
Problem: Internal hardware failure of the ultrasonic level meter, such as circuit board damage, sensor failure, etc..
Solution: Contact the manufacturer for repair or replacement.
Environmental factors:
Problem: Environmental factors such as temperature and pressure have an effect on ultrasonic propagation.
Solution: Calibrate and compensate according to the actual application environment.
Finally, it is recommended that you carry out regular maintenance and inspection when using the ultrasonic level meter to ensure the normal operation and measurement accuracy of the equipment.
