25 Flowmeter

The CDI 25 represents a price-performance breakthrough in compressed-air metering. It fills a need for low-cost measurement of air usage by individual pieces of industrial equipment. It indicates leakage and excessive usage locally with blinking lights, thereby eliminating the need for central monitoring and enabling equipment operators and maintenance mechanics to observe and respond to developing problems. $315.

Features

  • Low cost permits monitoring of loads throughout an industrial plant
  • Alarm functions indicate when leakage has developed or usage has become excessive
  • Totalizing function allocates usage and cost
  • Complete flowmeter in one package

​The CDI 25 is based on CDI’s proven technology, but it has been streamlined to reduce cost, reduce material usage and facilitate installation. The meter measures flow by maintaining one of its two probes warmer than the other; it calculates flow from the amount of heat required. Current flow, as well as minimum, average and totalized flows can be seen on a four-digit display.
