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. The AO55 blind analog transmitter can be used to convert to a 4-20 mA output. Electronic modules can be wall- or metermounted. (Note: PD10 available only as wall mounted unit.) IP meters are also compatible with the DL76 data logger and FT520 batch processor.
