Historically, Hot and Chilled Water flows have been measured by mechanical flow meters. However, as with any mechanical system, the meters are subject to wear and tear, poor repeatability and require regular maintenance and calibration. In addition, accuracy is relatively poor (1%-5% typical) and turndown is very limited (Usually 10:1 at best). Taken with the rapid rise in energy cost extreme scrutiny has been placed on an efficient, accurate, repeatable, and maintenance free flow measurement. This has taken the end user to look at non-mechanical flow measurement technology, which the Cadillac® Magnetic flow meters (CMAG & EMAG) were designed for and are ideally suited. Even though magnetic flow meters have been on the market for years, their high cost of manufacture has limited their use in these applications. Current manufacturing technology has made the Cadillac® magnetic flow meter a cost effective solution, especially in applications requiring high accuracy, low maintenance, obstruction free mounting, and analog (rate) or pulse (totalized) outputs.

The Cadillac® offering consists of two meters the CMAG and the EMAG. Sharing the same electronics platform the difference can be found in the flow tube design. Both meters offer a turn down of 100:1 or better.
