These units measure the water flow through your swimming pool type pipes.

It is often useful to see the water flow rate through the pipes on your pool or pond as this can be required to ensure that you have sufficient flow rate for heat pumps or filters

They can also be used for swimming pools or koi ponds or to measure the water flow through any 2" pipe.

A small hole is drilled in the pipe and the flow meter is mounted in the vertical (upright) position. A stainless steel clamp (included) holds the unit in place.
The units fit a standard 2" plastic pool pipe.


Other sizes are available for 1", 2", 2.5", 3", 4", 6" and 8" pipes - please email for details on these models


They show the flow in gallons per minute and litres per minute.

The range is between 40-150 Gallons per minute or 181-682 litres per minute

The unit straps around the 2" plastic pipes.
