Thank you in advance.
I have a process where water and flour are mixed together in one tank in batches, before being pumped out of the tank for further processing. The tank is conical.
The original design was to use a level transmitter to indicate two conditions. One, when enough water has been added to the tank. Two, when the tank was empty.
I tried using an ultrasonic but it failed often at telling when the tank was empty. I tried using a laser but that fails at both.
The tank is sanitary, meaning it has to be cleaned between batches. I fill it with cleanser and run the mixer.
I considered putting the tank on load cells but that's expensive, and I'm worried the vibration from the diaphragm pump will make the signals too noisy to determine when it is empty.
Thank you very much.
Brad
