Blue White F-300 Series 4 in. PVC Flow Meter for Horizontal Pipe, F-30400P

The Blue White F-30400P is the 4 inch F-300 Series PVC flow meter, a pitot tube (impact tube) design that mounts to existing horizontal pipe.

What it does

The meter measures flow from 2 to 10 feet per second, the pool industry standard, with full scale accuracy of +/- 5%. It needs no power. The body is one piece machined cast acrylic with PVDF internal float materials and no metals in the fluid path, so it is safe to use with salt chlorine generators. It has a UV and chemical resistant red cap and non-stick red float, and it is acceptable for outdoor installations in direct sunlight.

Installation

It mounts to existing pipe with no unions or adapters, and the stainless steel mounting clamps and gasket are included. It is calibrated to measure flow in Schedule 40 and Schedule 80 pipe (ASTM D-1785). F series meters must be mounted on horizontal pipe at the vertical, twelve o'clock position, and the pipe must be completely full of water at all times. For accuracy, allow a straight run of 10 times the nominal pipe diameter before the meter and 4 times after it, away from pumps, elbows, tees and valves. The design reduces straight run pipe requirements by 50%.

Ratings and before you order

The meter is rated to 150 PSI at 70 F and a maximum fluid temperature of 190 F at 0 PSI, with an ambient range of 14 to 110 F. These ratings apply to the meter only, and the rating of the pipe may differ. The meter reads flow in one direction only. Order the size that matches your pipe: this one is for 4 inch pipe.
