CDI 5400

FLOWMETER FOR COMPRESSED-AIR SYSTEMS - Rev. 3

•  Easy to install
•  Display rotates to facilitate use on horizontal  

or vertical pipes

•  No moving parts
•  Weather resistant and surge protected
•  Milliamp output
•  Pulse output convertible to threshold output
•  User-configurable scaling, filtering and units  

of measure

•  Optional wired and wireless outputs for networking

The CDI 5400 clamps onto a pipe, with two flow-sensing probes 
projecting into the pipe through 3/16-in. drilled holes. It seals 
directly to the pipe; no cutting or welding is required for installa-
tion. Because each flowmeter is made and calibrated for a 
specific size of pipe, the digital display indicates flow directly, 
with no setup or adjustment.
The meter measures flow by maintaining one probe warmer 
than the other. It determines the mass flow rate from the amount 
of heat required. The flow rate, in scfm or equivalent units, is 
shown on a large, four-digit display; a 4-20 mA output and a 
pulse output permit remote dis-play, totalizing and data collection.

(a)  Other sizes are available. Please contact CDI. For metering larger  

pipe sizes, please see our 5400 Series flowmeters.

(b)  Range of milliamp output and recommended maximum flow. Flowmeters 

for copper pipe have smaller ranges. Meters will function at somewhat 

higher flow rates but at reduced accuracy.
