The rotation of the rotor is detected by a non-drag Hall effect sensor. Output is a current-sinking pulse (square wave), which can be sent long distances (up to 2,000 feet) without a transmitter. This signal can be connected directly to PLC's, counters, and computer cards, as well as a variety of Seametrics controls and displays. 
Seametrics IP meters are ideal for chemical proportioning applications. If no display is required, a simple divider such as the PD10 provides adjustable pump pacing. For rate and total display, the FT415 (battery powered) or FT420 (loop powered) fow indicator can be mounted directly on the IP80-Series meter, or remotely on a wall or panel. The 
AO55 blind analog transmitter can be used to convert to a 4-20 mA output. IP meters are also compatible with the DL76 data logger and FT520 batch processor.The IP80-Series require special fttings that ensure correct depth placement in the pipe. Fittings come in a variety of materials for compatibility with specifc applications. Tee fittings are individually wet-calibrated at the factory and marked with the K-factor (pulses per gallon). Saddle fttings must be feld-installed on the pipe and do not come wet-calibrated. 
K-factors for saddles are based on factory-testing.
