Exploring Ultrasonic Blind Area in Ultrasonic Level Transmitters
Ultrasonic liquid level sensor users are well-acquainted with the existence of blind zones inherent in these devices. But what exactly constitutes the blind zone of an ultrasonic level sensor, and what factors influence it?
What is the Ultrasonic Level Sensor Blind Area
Comparable to the blind spot in human vision, the blind area of an ultrasonic water level sensor represents an area where the emitted ultrasonic pulses cannot simultaneously detect reflected echoes. This limitation arises from the specific time width of the emitted pulses, coupled with the ongoing vibrations of the sensor post-emission. The consequence is a small, immeasurable distance from the probe’s surface downward, known as the blind zone.
Factors Impacting Ultrasonic Level Meter Blind Zones
a. Working Principle: The blind zone is intricately linked to the working principle of the ultrasonic level meter. When encountering a measurement blind zone, pulse signals fail to reach that particular area.
b. Measurement Range: The blind zone correlates with the measurement range of the device. In industrial settings, regardless of the brand, ultrasonic level meters typically exhibit blind zones ranging between 300-500mm. Generally, devices with smaller measurement ranges tend to have smaller blind zones, while those with larger ranges often have correspondingly larger blind zones.
How to Deal With Ultrasonic Measurement Blind Zones
1.When aiming for precise measurements, it is crucial to consider the blind zone when determining the installation position of the device. Adequate margin and careful consideration of the transducer probe’s height during installation are essential for ensuring accurate level monitoring and safe instrument usage.
2.In situations where minimizing the blind zone is a priority, users can select ultrasonic level meters with smaller blind zones, typically ranging from 400-600mm. However, it’s important to note that devices with smaller blind zones often come with relatively smaller measurement ranges, usually around 600mm.
3.In the presence of foam, particles, or other substances on the liquid surface, measures can be implemented to ensure that ultrasonic waves are not excessively disturbed during propagation. Regular maintenance and calibration are essential to reduce blind zone issues stemming from equipment aging or errors.
