Why do Ultrasonic Tank Level Sensors Fail?
There are several potential reasons why an ultrasonic tank level sensor may fail. Some common causes of failure include:
Ultrasonic tank level sensors should never be used on Tanks that contain chemicals that out-gas or create a vapor (also known as a vapor blanket). Some of the most common chemicals that creates a vapor or out-gas are Nitric Acid, Hydrochloric Acid (HCL), and Sodium Hypochlorite (Sodium Hypo/ Hypo/ Bleach)
Debris or contaminants in the fluid: If the fluid in the tank contains debris or contaminants, such as dirt, rust, or other particles, these may interfere with the operation of the sensor. The debris or contaminants may cause the ultrasonic pulse to be absorbed, scattered, or reflected in unexpected ways, which can result in inaccurate or unreliable measurements.
Temperature fluctuations: Ultrasonic tank level sensors may be sensitive to temperature fluctuations, and may not be able to provide accurate measurements if the temperature of the fluid in the tank changes significantly. This is especially true if the temperature range of the sensor is exceeded.
Vibration or shock: Ultrasonic tank level sensors may be sensitive to vibration or shock, and may not be able to provide accurate measurements if the sensor is subjected to excessive vibration or shock.
Turbulence: If the power supply to the sensor is disrupted, the sensor may not be able to operate properly. This can result in inaccurate or unreliable measurements.
Condensate: Small water droplets collect on the transducer of the tank level sensor causing the sound pulse to attenuate.
Sensor degradation: Over time, the sensor may degrade or wear out, which can result in inaccurate or unreliable measurements.
Overall, there are a number of potential reasons why an ultrasonic tank level sensor may fail. In order to ensure reliable and accurate measurements, it is important to properly maintain the sensor and ensure that it is operating within its specified temperature, vibration, and power supply range.
