More of a sensor questions here:
I am working on a project where I am using an ultrasonic sensor to detect the level of sludge build up in a tank or pipe. I plan to install the ultrasonic sensor at the top of un upside down TEE fitting that is installed in-line of a sanitary pipe.
The goal is to be able to measure the build up of sludge at the bottom of the pipe using the ultrasonic sensor at the top of the TEE pointing down.
My questions is: Will the ultrasonic sensor be able to detect the build up of sludge at the bottom of the pipe? even considering the fact that water will be passing through periodically?
