How you do a fuel flow meter installation can effect its performance, so pay close attention to these flow meter installation tips. Otherwise, your screen might read 2.0 when it should be reading 0.2.
1. Make sure all of your fuel lines are straight and supported for at least a foot in either direction beyond the meter. Bends in the line beyond a foot should be at as low an angle as possible. Abrupt bends cause turbulence, and when the air bubbles get sucked into the meter’s paddlewheel, it causes inaccuracies.
2. Ensure your hose clamps are stainless-steel. Many that are advertised as stainless (and are shipped with these units) have screws that are a lower grade metal, and will corrode away. Check out the hose clamps on this Northstar fuel flow meter:
