Emerson \/ Rosemount<\/a><\/strong> manufactures a broad line of flow meters, serving the industrial process, municipal water, and municipal wastewater industries. Here at SCADAmetrics (Wildwood, MO)<\/a><\/strong>, we manufacture flow metering instrumentation in support of these industries, with the stated mission of helping users extend such meters for enhanced SCADA and AMI interoperability and functionality.<\/p>\n\n\n\n

Like many manufacturers of process-oriented flow meters, Rosemount’s signaling options are focused upon 4-20 milliamp, pulse, Modbus, and HART. Today, the new SCADAmetrics model PTE Pulse Encodalizer\u2122<\/a><\/strong> is able to leverage the available pulse output on the Model 8750w magnetic flow meter<\/strong> (and others) to generate additional AMI signaling and display options \u2014 thereby bridging the gap to solve the unique challenges facing the Utility AMI sphere<\/strong>.<\/p>\n\n\n\n

Within each Rosemount 8750w (and certain other model) Transmitter, a pulse-per-volume output terminal is available. This output can be converted into a 3-wire encoded signal \u2014 using a SCADAmetrics model PTE Pulse Encodalizer \u2014 to provide a utility AMI system with forward totalized flow.<\/p>\n\n\n\n

Forward Totalization Reported to AMI System<\/h2>\n\n\n\n

The following graphics illustrate how the Pulse Encodalizer can be used to transmit Forward Totalization to an AMI\/AMR system. Most (but not all) municipal metering applications are uni-directional (forward flow only). Note the connection from the 8750w Transmitter Pulse Output Terminals (Pulse+,Pulse-) to the Pulse Input Terminals of the Encodalizer (Terminals 2,3):<\/p>\n\n\n\n

Conclusion<\/h2>\n\n\n\n

The PTE Pulse Encodalizer<\/strong> translates the Rosemount 8750w magnetic flow meter pulse count to a connected AMI\/AMR system using the industry-standard, 3-wire encoded protocols: both Sensus Protocol<\/strong> and Neptune Protocol<\/strong>. Therefore, all major AMI systems are supported.<\/p>\n\n\n\n

The Encodalizer is powered by a user-replaceable battery pack, which offers a life up to 10 years. The Encodalizer features a 9-digit LCD display of the Pulse Count \/ Totalization. When commissioning the Encodalizer, the user should pre-edit the 9 digits \u2014 in order to synchronize<\/strong> (match) with the totalization displayed on the LCD screen of the Rosemount 8750w.<\/p>\n\n\n\n
