Dosing pump accuracy and preventing overdosing

Post by tngo »

How often would the dosing pump require calibration and how accurate are they? I was thinking about adding dosing pumps but I'm always concerned that a relay could get stuck to the on position and poof there goes the tank. Is there a separate timer or relay that I could add independent of the RA to would shut off power to the doser after a set time regardless of what the RA does?
