The CDI-5400-20S is a flowmeter for compressed air systems.
It measures flow by maintaining one probe warmer than the other.
It calculates the mass velocity from the amount of heat required, and then calculates the flow on the basis of pipe area.
This model fits 2' steel pipes.

Analog or Pulse output, user selectable.
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 adds the ability for users to be able to measure compressed air flow (SCFM).
  • Easy to install
  • Digital display
The CDI-5400-20S Sensor is for use in Indoor environments

The CDI-5400-20S Sensor supports the following measurements : Compressed Air Flow
Power supply:
We supply each meter with a wall-plug DC supply for 110 V to 230 Volt AC main with a 1.5 meter cable plus a 4.2 m extension cable. Prongs for Euro-pean, UK and US outlets are provided, as appropriate. The meter may alternatively be hard wired to a 24-Volt dc supply. Eighteen Volt supplies furnished with some earlier CDI flowmeters must not be used.
