The HFS-xx is designed to spray up to 1600 cc/min. At lower, you willbe operating at the boottom end of the designed range. In this range, unless the inlet restrictor is well, match, you will be getting some overflow.

All the turbine flow sensor also over reads a little as it accellerates towards a steady flow. We are bring put a range of smaller valves in the next few months. Beta test is available now. Howerton do have a few but not many untill full production.
