Siemens<\/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, Siemens’ signaling options are focused upon 4-20 milliamp, pulse, Modbus, and HART. Today, the new SCADAmetrics model PTE Pulse Encodalizer™<\/a><\/strong> is able to leverage the available FM MAG 5000 pulse output 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 Siemens FM MAG 5000\/6000 Transmitter, a pulse-per-volume output terminal is available, as well as a flow-direction relay terminal. One of both of these outputs can be configured to provide a utility with an encoded AMI signal of forward totalized flow (one Encodalizer), or encoded AMI signals of both forward and reverse totalized flow (two Encodalizers).<\/p>\n\n\n\n

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

The following graphic illustrates 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 FM MAG 5000\/6000 Transmitter Pulse Output (Terminals 56,57) to the Pulse Input Terminals of the Encodalizer (Terminals 2,3):<\/p>\n\n\n\n

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

As a demonstration of even more advanced capability, the following graphic illustrates how two (2) Pulse Encodalizers can be utilized to transmit BOTH Forward Totalization and Reverse Totalization. This solution leverages the FM MAG 5000\/6000’s inherent ability to control an internal Form-C relay based upon flow direction, combined with its pulse output channel.<\/p>\n\n\n\n

The Siemens Mag 5000 pulse output should be set for the desired pulse weight (eg Gallons per Pulse) and pulse width (~100-150 msec is optimal). The following video by my friend Norm Kramer<\/strong> @ Siemens provides additional guidance:<\/p>\n\n\n\n
