Founded in 1899 as the Swiss branch of a measuring instruments company, GWF Group (Lucerne, Switzerland)<\/a><\/strong> has evolved into a globally leading provider of solutions for the water, gas, electricity, and heat industries.<\/p>\n\n\n\n

The Sonico Edge<\/strong> (pictured below) is a mains-powered ultrasonic water meter manufactured by GWF. <\/p>\n\n\n\n

Ultrasonic flow meters are based upon the principle of measuring liquid flow as proportional to transit-time of sound waves traveling across water flowing through a closed pipe. Read more here.<\/a><\/strong><\/p>\n\n\n\n

Ultrasonic flow meters have no moving parts, and also have no protrusions into the flow tube \u2013 thereby lending themselves as suitable for both filtered and unfiltered water applications.<\/p>\n\n\n\n

The Sonico Edge is available with optional SCADA connectivity modules, which include a pulse (totalizing) output, a 4-20mA (flow) output, Serial output, and the Modbus\/RTU (RS.485) industrial protocol.<\/p>\n\n\n\n

\n\n\n\n

Today, the latest release of the SCADAmetrics Model MBE Modbus Encodalizer<\/a><\/strong> now adds UI.1203 (Sensus) protocol and Neptune ECODER.PLUS protocol to this important flow meter, so that it may now be easily integrated into modern potable water AMI\/AMR systems.<\/p>\n\n\n\n

The operational convenience of the MBE Encodalizer is based upon the principle that the User sets the Meter Type (Make & Model) via Encodalizer DIP switches, connects the Encodalizer to the meter via Modbus\/RTU (2-Wire RS.485), and the Encodalizer interacts with the target meter using the meter\u2019s factory default Modbus\/RTU settings. Therefore, zero setup of the Sonico Edge is required.<\/p>\n\n\n\n

\n\n\n\n

Important Note:<\/strong> As of the date of this Article, the MAXIMUM MODBUS TOTALIZER VALUE of the GWF Sonico Edge flow meter is 9,999,999.9 Gallons. When the meter exceeds this maximum, its Modbus totalizer rolls over, and the totalizer counter restarts from 0.0 Gallons. For comparative reference, a typical AWWA-style 6 Inch flow meter generally features a MAXIMUM TOTALIZER of 999,999,990.0 Gallons before rollover. The relatively low rollover value of the Sonico Edge may result in an excessive rollover frequency for your application.<\/em><\/p>\n\n\n\n
