Datasheet: The Flow meter clamps onto a pipe, with two Flow sensing probes projecting into the pipes through 5mm. drilled holes. It seals directly to the pipe; no cutting or welding is required for installation. Because each Flow meters is made and calibrated for a specific size of pipe, the display indicates Fow directly, with no setup or adjustments. 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 larger 4 digit display 485 output and pulse output permit remote display, totalizing and data collection.
