| General Information The PW Series are impeller-type insertion meters designed for use in pipe sizes 1/2" to 8". High-quality jewel bearings and nickel-bound tungsten carbide shaft are used for maximum life and extreme low friction. Bodies are machined from solid rod for maximum precision. The rotation of the rotor is detected by a non-drag Hall-effect sensor. Output is a pulse-type square wave, which can be sent long distances (up to 2,000 feet) without a transmitter. This signal can be connected directly to controls, as well as PLC's, counters, and computer cards. PW meters are ideal for chemical proportioning applicaͭtions. For rate and total display, as well as pump pacing, the FT415/420 flow indicator can be mounted directly on the PW Series, or remotely on a wall or panel. The PW Series require special fittings, since they are not depth-adjustable. Installation in the fitting ensures correct depth placement in the pipe. Fittings are made of PVC, and are included in the model selection. Two inch diameters or less are installed with a pipe "T" (included). Three inch diameters or larger come in a "Saddle" which slips over the pipe and requires a hole to be drilled. | Specifications | ||||
