Description
IP800-Series are impeller (or “paddlewheel”) insertion meters designed for use with a wide variety of liquids in pipe sizes 1/2” to 8”. Sensors are available in brass, 316 stainless steel, PVC, and polypropylene. Bodies are machined from a solid rod for maximum precision. High-quality jewel bearings and nickel-bound tungsten carbide shafts are used for extreme low friction and long life. Low-flow performance is good, although other Seametrics flow meters are recommended where extremely low flows are being measured. The rotation of the rotor is detected by a non-drag Hall-effect sensor. Output is a current-sinking pulse, 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, a modular system of electronics can be installed directly on the flow sensor or mounted
remotely. The FT430 (externally powered with pulse), FT440 (loop powered), and FT450 (battery powered) all provide digital rate and total
displays, as well as a programmable pulse; the FT440 also provides a 4-20 mA analog output. Electronic modules can be wall- or meter- mounted. The IP800-Series require special fittings that ensure correct depth placement in the pipe. Fittings come in a variety of materials for
compatibility with specific applications. Tee fittings are individually wet calibrated at the factory and marked with the K-factor (pulses per gallon). Saddle fittings must be field-installed on the pipe and do not come wet calibrated. K-factors for saddles are based on factory-testing
