Jim ‘Slim’ Mimlitz, SCADAmetrics<\/p><\/div>Recently, an interesting project was completed at the water custody-transfer point between Williamsville (IL)<\/a>\u00a0and Springfield (IL)<\/a>, where\u00a0Williamsville purchases bulk water from Springfield and\u00a0transmits it through a system of water towers, pumping stations, and distribution mains.<\/p>\n

\"\"<\/a>

Williamsville (IL) Pumping Station. Station features a Ground Storage Tank and Altitude Valve, a Master Meter, 2 Pumps, and a Bypass Valve. Williamsville’s station is run by an intelligent RTU connected to their Radio SCADA system. Springfield, the bulk seller, monitors the master meter using an Itron radio AMR system.<\/p><\/div>\n

In the scope of this\u00a0project, Williamsville installed EtherMeters<\/a> into their existing distribution SCADA system for the purpose of automated report generation, flow monitoring, and leak detection.The custody-transfer master meter was a Badger<\/a> 6 Inch T2000 Turbo Meter<\/a> outfitted with an ADE Encoder Register<\/a>\u00a0and supplied by Midwest Meter (Edinburg, IL)<\/a>.\u00a0\u00a0\u00a0Springfield\u00a0concurrently wished to read this meter using\u00a0a 60W ERT Endpoint<\/a> (manufactured by Itron<\/a>) as part of its radio-based AMR system.\u00a0 It\u00a0was important to both parties that Williamsville’s\u00a0SCADA\/metering system\u00a0and Springfield’s AMR system coexist without disruption to the other’s system.<\/p>\n

\"\"<\/a>

Vault-Set Master Meter: 6 Inch Badger T2000 Turbo Meter. Meter is equipped with an ADE encoder-type register and an Itron 60W ERT.<\/p><\/div>\n

To achieve\u00a0harmonious sharing of the master meter, it was necessary to split the meter signal using\u00a0a SCADAmetrics\u00a0RRF-50 “Radio-Read Filter”<\/a>.\u00a0 This unit\u00a0was installed\u00a0within a small junction box within\u00a0the master meter vault,\u00a0essentially allowing the two meter-reading devices to be connected in parallel to\u00a0the single encoder-based register.\u00a0 The vault did not contain power, but this was not\u00a0 a hindrance, since the Radio-Read Filter does not require an external\u00a0power source.<\/p>\n

SCADAmetrics Radio-Read Filter. This device allows two endpoints to share the meter readings. In this case, the two endpoints are the Itron 60W ERT (Seller) and an EtherMeter (Buyer). Although the Radio-Read Filter is not rated for an uncontrolled vault environment, the customer potted the unit with a two-part 3M epoxy compound to resist moisture.<\/p><\/div>\n

The flow-metering upgrade to Williamsville’s SCADA system provides tracking of total and zoned consumption \u2014 a vital tool for detecting and pinpointing leaks.<\/p>\n

A Few Useful Application Notes (Courtesy of Itron Technical Support):<\/strong><\/p>\n

1.<\/strong> The Badger ADE register for the 6 Inch T2000 Turbo Meter was pre-fitted\u00a0with an Inline Connector for\u00a0the Itron W60 ERT Endpoint.\u00a0 The internal conductor color-coding for this type of cable is non-standard.\u00a0 The color-coding is as follows: BLACK (Tx or CLK), RED (Rx or DATA), SHIELD\/DRAIN (CMN).<\/p>\n

2.<\/strong>\u00a0Before initially connecting an Itron 60W ERT endpoint to the ADE register, ERT initialization is sped up\u00a0applying the Itron-supplied shorting cap to the ERT.\u00a0 This places the ERT into fast-mode for 15 minutes or until the ADE register is recognized (whichever time period is shorter).\u00a0 Internally, the cap places a jumper\/short across the Rx\/DATA line (RED)\u00a0and the CMN line (SHIELD).<\/p>\n
