Rosemount<\/a><\/strong> manufactures a broad line of process instrumentation and 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 instrumentation, Rosemount’s signaling options are focused upon 4-20 milliamp, pulse, Modbus, and HART.<\/p>\n\n\n\n

Today, the new SCADAmetrics model PTE Pulse Encodalizer\u2122<\/a><\/strong> is able to leverage the available Relay (Pulse) output from a Rosemount model 3490 Open-Channel Flow Meter Transmitter<\/a><\/strong> 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 3490 Transmitter, programmable relay outputs are available. One of these outputs can be configured to provide a pulse-per-volume output to a SCADAmetrics model PTE Encodalizer and thereby connect to a utility AMI system.<\/p>\n\n\n\n

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

The following graphic illustrates how the Pulse Encodalizer can be used to transmit Totalization to an AMI\/AMR system. Note the connection from the Rosemount 3490 Relay (Pulse) Output. In this example, 3490 Relay #1 (Terminals 11, 13) is connected to the Pulse Input (Terminals 2, 3) of the Encodalizer:<\/p>\n\n\n\n

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

The PTE Pulse Encodalizer<\/strong> translates the Rosemount 3490 totalizer 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 3490.<\/p>\n\n\n\n
