Minimum range is not a fixed property of a sensor. It is set by the blanking interval the electronics impose — and by whether the transducer stops ringing fast enough to let you shorten it.
TTL, PWM, and Analog Outputs: How to Get Distance Data Out of an Ultrasonic Sensor Read Post »
How electrostatic ultrasonic sensing turns distance readings into stockpile volume estimates — aiming at the peak, treating lost echoes off steep flanks as missing data, and matching a geometry model to how each pile is built. Key answers at a glance Can ultrasonic sensors measure stockpile volume? Indirectly. They measure distance to the pile surface,
Most false level readings trace to one of a handful of causes, and only two of them are solved by changing the sensor. Sorting the symptom first saves a lot of ladder time. Key answers at a glance Why does a bin read empty when it is full? The return off the peak of a
