i just noticed that the flow meter in my aquabay m1 is not spinning. i investigated it, no tubings where bent, pump is running, everything in my loop is ok. but then i saw that there are some small material (i have no idea what it is) inside the flow meter that is blocking the spinning thingy. my question is, is it ok if i leave this not spinning for the mean time? my temps are ok and not going up. i would flush out all the water and take the mateials out but i don't have any coolant at the moment. is it ok if i leave it till i get some coolants? will it affect anything?
