Pipe Adapters mount the flow meter to pipes of various sizes and schedules. Specific to each pipe size and schedule, an adapter for a 3" schedule 40 pipe will not work on a 3" schedule 80 pipe. The user can program the Pipe Mounted Display Meters or the Remote Display Flow Meters for any of these adapters. The same meter head can be moved to different locations by purchase additional adapters and plugs.
Most difficulties with all 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, biological growth, 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. Please read this page for selection and mounting location advice.
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. Schedule 40 and 80 pipe have the same outside dimensions. Therefore our schedule 80 section of pipe will glue up to your existing schedule 40 pipe. Installation consists of removing a section of the existing pipe, coupling in this new section of pipe, allowing the glue to dry and restoring the flow.
These pipe adapters mount directly on your existing plumbing. The adapter and pipe are cleaned and coated with either PVC cement or silicon sealer. Then, to secure the adapter to the pipe, stainless steel clamps are installed. Next, using the adapter as a guide, a 1½” hole saw is used to bore through the pipe. We stock adapters to accommodate schedule 40 and schedule 80 pipe. Other pipes will require a custom-machined adapter. (See section below)
These are saddle mounted adapters that are specifically machined to your pipe dimensions. A pipe with a smooth outer surface is required. In order to machine the adapters, the outside diameter and wall thickness of the pipe will be required. The adapters look and mount the same as the saddle style depicted above. The accuracy of the meter is greatly affected by the depth the paddle wheel is inserted in the flow. Therefore, wall thickness of the pipe must be accurate to within 0.010”. You need to call (715-523-1268) to have these custom machined.
The plug allows the meter to be removed and then the water flow restored. Allow for cleaning and servicing of the meter. One size plug fits all of the adapters.
The paddle wheel and pin are normal wear items. Typically, in clean water, they last for many years of continuous service. Silt/grit or chemicals in the water will shorten the life of the paddle and pin. Changing the paddle consists of pushing out the old pin and installing the new paddle and pin.
