Pipe Adapters
These adapters mount the paddle wheel flow meter to pipes of various sizes and schedules.
Most difficulties with flow meters are traceable to improper mountings and/or improper pipe sizing. Paddle wheel flow meters rely on the momentum or movement of water to spin the paddle and keep it free of debris, sediment and air bubbles. Reduced accuracy and fouling problems are typical when pipes are over sized and flow rates are not within the recommend range. Pipes must remain full of water at all flow rates. This is especially critical when monitoring downward flows on vertical runs.
This system offers the simplest installation procedure
and is cost effective for pipes 4” in diameter and smaller. These
13” pipe sections are available in sizes ranging from ½” to 4”.
The smaller sizes are only offered in schedule 80. Installation
consists of removing a section of the existing pipe, coupling in the
Pipe Mounted Adapter, allowing the glue to dry and restoring the
flow.

Saddle
Mounted Adapter
These adapters mount directly to the existing plumbing. The adapter and pipe are cleaned and coated with either PVC cement or silicon sealer, then using the stainless steel clamps, the adapter is secured to the pipe. Next, the adapter is used as a guide, and 1½” hole saw is used to bore through the pipe. These adapters will only accommodate schedule 40 and schedule 80 pipe; other pipes will require a custom-machined adapter. (See section below)

Custom Saddle Adapters
These custom adapters are machined for pipes with smooth outer surfaces. In order to machine the adapters, the outside diameter and wall thickness of the pipe are required. The adapters look and mount the same as the saddle mounted adapter depicted above. The accuracy of the meter is greatly affected by the depth the paddle wheel is placed in the flow; therefore, wall thickness of the pipe must be accurate to within 0.010”.
