Installation Guidance

Where should I place the F-300 flowmeter along my plumbing system?

Blue-White specifically recommends installing the F-300 downstream from the filter to prevent debris from entering the meter. Putting it before the heater is also good — it stays in cooler water, and you avoid any turbulence the heater might add.

What kind of pressure can this F-300 flowmeter tolerate?

The F-300 (horizontal model like the F-30150P) is rated for 50 PSI maximum working pressure at 70°F.  That should be within range for most residential pools, unless it's a commercial application.  Check your filter pressure gauge to ensure your system is within tolerances.

What amount of straight-pipe length do I need before and after the flowmeter to ensure an accurate read?

Per Blue-White's current installation guidance, the distance required for accuracy is 5 times the nominal pipe diameter before the meter and 2 times the nominal pipe diameter after the meter.  Thus for 2" pipe that works out to:

• Upstream (before): ~10 inches minimum of straight pipe
• Downstream (after): ~4 inches minimum of straight pipe

Are there other important things I should be aware of for installing this flowmeter?

Yes, there are several that include:

• Must be mounted on a horizontal pipe run with the meter at the 12 o'clock (top) position.
• Pipe must run completely full of water at all times.
• It's calibrated for Sch 40 or Sch 80 PVC only — mounting on other pipe sizes may cause pitot tube interference or inaccurate readings.
• Flow direction matters — the pitot tube has to face into the flow (there's an arrow on the meter).
