Ultrasonic Sensor Mounting Tips

ultrasonic sensor mounting is critical to proper performance

Proper mounting is critical for the successful operation of an ultrasonic sensor. Mounting mistakes are one of the most common installation pitfalls with ultrasonics. However, it doesn’t have to be difficult.

Here are a few practical guidelines that can help ensure trouble free installation for your ultrasonic level sensors.

Make sure the face of the sensor is perpendicular to the target surface. If the sensor is a few degrees off perpendicular the target may not be detected.

Mount the sensor in a location that provides an unobstructed column of air from the sensor to the target. Generally speaking you need a 3-4 foot diameter unobstructed column even at longer ranges. Stilling wells provide a good solution for liquid level applications where an unobstructed path to the target is difficult.

Always mount the sensor above the highest anticipated target level by at least the minimum blanking distance. The blanking distance is usually between 4 – 12 inches depending on the model sensor you are using.

Mount the sensor away from any fill spouts. Mounting too close to the spout could result in false readings. White noise can also be a problem, as it can interrupt the sound wave.

Avoid mounting the sensor in the direct center of a tank if there is a domed top. The shape of the top could amplify small undesired signals inside the tank.

Mount the sensor away for tank walls especially if the walls are corrugated or if there will be product buildup on tank walls.

If the sensor will be mounted outdoors try to shade the sensor from direct sunlight. This can harm the sensor housing and cause overcompensation for temperature as the sensor heats up.

Following these simple guidelines can help your ultrasonic level sensor perform to its maximum capabilities and provide you with worry free readings.
