Frequently Asked Questions

How do I know what size meter I need?

You determine this not by matching pipe size, but rather by the flow rate of the water moving through the water line. Once you know your flow rate as measured by gallons per minute (gpm), you may then click on the “Technical Specification” icon at the top of this page. Each meter technical specification page defines maximum flow rates that our meters will handle. Please be advised that continual operation of a meter at/or close to the maximum gpm capacity defined may reduce the functional life of the meter. Carlon offers meters from ½” – 20”.

How do I correctly install my Carlon meter?

•Flush the line thoroughly to eliminate the possibility of foreign material reaching the meter and in-line valves.

• Install horizontally, register facing up and the meter inlet port facing the water supply line.

•Provide the following minimum length of straight unobstructed pipe section upstream of meter as follows:

 

Inlet path – one bend = 5 x diameter

Valves = 12 x diameter

Two bends or one tee and one bend or 

bends at random = 25 x diameter

in an inclined orientation?

It is recommended that you install your Carlon meter horizontally with the register facing up and the meter inlet port facing the water supply line.
