Re: Tutorial: Reading Water Flow rate with Water Flow Sensor

The best possible solution for filling glasses or other "reasonably" sized containers, is to use a dummy measuring container in between the storage container and practical container. Arrangement goes like this: You have flow sensor and automated valve on bottom of the measuring container. The measur...

dnordenberg: No, you don't care about them. We need to look only the pulses during the 1 second period for our calculation of flow. The problems will come up only if the flow will change a lot in a short period of time, instead of being (almost) constant.

Re: Tutorial: Reading Water Flow rate with Water Flow Sensor

eltoddo: Yes, it will be off 1.5cl in the worst case. If, and only if, the accuracy is constant for a certain device, it can be configured. Lets say you have constant -1% error in measured vs. real value, (aka. 50cl measured, 50.5cl real) you pull 1.01 as multiplier into the code. In +1%, you use 0...
