How CDI Meters Provides Monitoring Software and Serial Communication

Updated

CDI Meters flowmeters support serial communication and work with free monitoring software, so you can read compressed-air flow data without building a custom data pipeline. The meters themselves install in minutes, and the software is provided at no cost according to the site. This setup fits sites that want cost-effective compressed-air monitoring and can connect a serial interface to a computer or compatible system. If your existing control system only accepts other protocols, you will need to confirm compatibility before relying on this path.

What the monitoring setup includes

CDI Meters describes three connected pieces:

  • Flowmeters that install in minutes.
  • Serial communication between the meter and a monitoring device.
  • Free monitoring software for viewing the data.

The purpose is insight that helps manage compressed air and save energy. In practice, the meter measures flow, sends readings over a serial connection, and the software displays them so you can spot waste or verify savings.

How the data path works

The general flow is:

  1. Meter measures compressed-air flow at the installation point.
  2. Serial communication carries the readings to a connected computer or system.
  3. Monitoring software receives and displays the data.

Because the site specifies serial communication rather than a network or cloud protocol, the practical question is what your receiving device supports. A typical setup uses a computer with a serial port or a USB-to-serial adapter, running the provided software.

What you need to confirm

  • Serial interface availability on the device that will run the software.
  • Cable and adapter matching the meter's serial connection to your computer.
  • Software installation on a machine that stays connected if you want continuous monitoring.

Available meter models

The site lists these models: 5200, 5250, 5400, 5450, and 5100. Model choice affects the installation scenario — for example, hot-tap meters are offered for systems that cannot be shut down. If uptime matters, that option lets you install without stopping the compressed-air system.

Why this matters for energy management

Compressed air is an expensive utility, and unmeasured leaks or misuse often go unnoticed. Continuous flow data from a meter plus monitoring software turns that into something you can act on: you see baseline consumption, detect abnormal flow, and verify whether efficiency measures actually reduced usage. The site frames the whole package — quick installation, serial communication, free software, hot-tap options — as a way to make this monitoring cost-effective and easy to implement.

Common sticking points

  • No serial port on your computer. Use a USB-to-serial adapter, and confirm the software recognizes it.
  • Existing system uses a different protocol. The site describes serial communication; if your plant network expects Ethernet or another standard, verify how you will bridge the two.
  • Intermittent monitoring. If the computer running the software is not always on, you lose continuous data.
  • Installation during operation. Choose a hot-tap model if the system cannot be shut down.

If your goal is simply to read compressed-air flow data and act on it, the CDI Meters approach — meter, serial link, free software — covers that with minimal setup, provided your receiving device can accept a serial connection.
