Hello friends,
I am dealing with the automation of a fuel dispensing facility, to deliver fuel from storage tanks to heavy vehicles. From the tanks there is a PD pump (actually a few) and then a meter and a valve. I understand about taking the pulses from the meter (to count the volume) and controlling the valve (to control/stop the flow). But what I am not sure of is what to do with the pumps. Are they supposed to be on all the time? Should I shut off the pump after I have closed the valve? (i.e. desired quantity is reached)
Thank you
