CDI flowmeters represent a radical departure from conventional designs. The meter clamps around the pipe with its flow-sensing probes projecting into the pipe through drilled holes. The low cost of the meters makes them ideal for installation throughout an air distribution system.
All of our flowmeters:
- measure mass flow via thermal dispersion
- are CE certified and RoHS compliant
- have built-in LED displays
- require no calibration
Our most popular thermal dispersion flowmeters, offered at a low cost ideal for installation in an air distribution system. 5000 Series (standard) are available in a variety of sizes for steel, copper, and aluminum pipe.
- Easy to install
- No moving parts
- Digital display
- Milliamp and pulse outputs
- No calibration or setup required
- Complete flowmeter in one package
- Optional RS-485 output for networking
This meter operates seemlessly with our HOBO data loggers for recording air flow in energy monitoring applications.
Models: U30, H22, U12, ZW are all suitable
Requires analog port selection during U30 system configuration and use of a S-FS-CVIA when using the H22-001 logger. When using a U12 logger, this sensor requires a 4-20mA input cable (CABLE-4-20mA).
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 and6400 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-5400and 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, for 5" and 6" pipe.
