Compressed Air Flowmeters
Drill Guides are required in most situations to successfully install any CDI flowmeter. The meter's flow-sensing probes project into the pipe, and these guides ensure that the drilled holes are properly aligned. If the pipe can be placed in a milling machine to locate holes, a Drill Guide may not be necessary.
Drill Guides are reusable for multiple installations, so if you already have the right guide you're in luck. However, if you haven't purchased flowmeters from CDI before, you'll need a Drill Guide.
This universal guide is for use with all CDI-25, 5200 and 6200 meters (pipe sizes 1.5" or less). It includes a 3/16" drill bit, 3/16" and 1/4" hex wrenches, and an aluminum drill guide with two 3/16" drill bushings spaced 2.250" apart. These guides can be attached to the pipe with a band clamp, a C-clamp or a chain clamp.
This universal guide is for use with all CDI-5400 and 6400 meters (pipe sizes 2" or greater). It includes a 3/16" drill bit, 3/16" and 1/4" hex wrenches, and an aluminum drill guide. These guides can be attached to the pipe with a band clamp, a C-clamp, or a chain clamp.
This guide is for use with 2" (50 mm) and 2-1/2" (63 mm) CDI-5400 and 6400 flow meters. It includes a 3/16" drill bit, a 5/16" hex wrench, and an aluminum drill guide and is a cheaper option than the universal guide if you're only working with these specific pipe sizes. These guides can be attached to the pipe with a band clamp, a C-clamp, or a chain clamp.
These half-ring drill guides are for use with specific sizes of CDI-5400 and 6400 meters (3" or larger). They attach to the pipe by bolting into the rear half-ring that comes with the meter. They include a 3/16" drill bit, a 5/16" hex wrench, and a half-ring of the appropriate size to match your meter. When ordering, specify "XXX" to match your meter size (either 30C, 30S, 40C, 40S, 50S, or 60S). Guides for 4" pipe or smaller are $65, for 5" and 6" pipe are $95.
