Flow meters
show you exactly what your flow rate through your system is at any time. Your
price is $65 for the 2" mount.
They can be used for balancing different inputs like multiple bottom drains
and skimmers.
The meters fit into a hole drilled in the PVC pipe, and then
their rubber saddles are held tightly against the pipe with hose clamps.
The
flow meters are designed for the pipe diameters in either PVC or copper.
