Product Details

The CDI 5200 clamps onto a pipe, with two flow sensing probes projecting into the pipe through 3/16 inch drilled holes. It seals directly to the pipe; no cutting or welding is required for installation. 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 calculates the mass velocity from the amount of heat required, and then calculates the flow on the basis of pipe area. The flow rate, in scfm, is shown on a large, four digit display; a 4-20 mA output and a pulse output permit remote display, totalizing and data collection.
