Hi,
You can purge this using a rotameter (variable area flow meter) which are quite inexpensive. The instrument should be zero'd on site.
Why is only HP side plugging?

Hi,
I agree with you that the pressure should be equal on both legs, therefore there is a restriction in one of the legs. Have the maintenance people ream out the tubing.
Hacksaw has a good point about the process surges. Try slowing down the rate that the spray operates.
