CDI Meters 5400 Manual

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.

for copper pipe have smaller ranges. Meters will function at somewhat
higher flow rates but at reduced accuracy.
