In 2012, SCADAmetrics introduced the B202 — an Industrial Bell 202 Modem designed for Radio Telemetry Applications. The B202 is designed to provide external, non-proprietary data modulation/demodulation for a wide range of popular narrowband analog telemetry radios, including models from Ritron, Tecnet/Maxon, GE/MDS, RF Neulink, and Calamp. We recently performed extensive laboratory and field validation Read More →

In recent months, we’ve been receiving regular requests from non-industrial-controls clients who wish to build an AMR System around the EtherMeter.  Examples include owners and managers of commercial properties, such as apartment buildings and strip malls.  In most cases, this category of client works in the commercial sub-metering realm, and therefore does not have prior Read More →

This article describes how to use an EtherMeter to connect a Tipping Bucket Rain Gauge to a SCADA System, yielding a realtime rainfall measurement system that communicates using Modbus, DF1, and EtherNet/IP. This rain measuring instrumentation was a component of the new SCADA System at the DesMoines & Mississippi Levee District (Alexandria, MO).  The electronics were Read More →

In addition to its ability to read most encoder-type flow meters, the EtherMeter also features pulse-input support. The following Application Note details the procedures for connecting a Sensus High-Speed Pickup (Pulse) Register to an EtherMeter; and it also describes an example of modified Setup Menu parameters for the High-Speed Pickup: http://scadametrics.com/PDF/App_Note_014.pdf Note that the Sensus Read More →

Recently, an interesting project was completed at the water custody-transfer point between Williamsville (IL) and Springfield (IL), where Williamsville purchases bulk water from Springfield and transmits it through a system of water towers, pumping stations, and distribution mains. In the scope of this project, Williamsville installed EtherMeters into their existing distribution SCADA system for the purpose of automated report Read More →

The EtherMeter contains an RS485 port for Modbus/RTU and DF1 communications in multi-drop applications. When using the RS485 port, the following EtherMeter terminals are used: 19  –  RS485A (-) 20  –  RS485B (+) 21  –  Signal GND Reference (contains current-limiting resistor) In order to use RS485, attention should be given to the EtherMeter’s dip switch positions: Switch 1  Read More →

The Preciseline Pressure Transducer (manufactured by Keller-America ), like our EtherMeter, offers a digital Modbus-based solution to a water telemetry problem that was previously solved by analog (4-20mA) instrumentation. In the case of the Preciseline, the water pressure signal is converted into Modbus; whereas in the case of our EtherMeter, error-free totalization and flow-rate data is collected Read More →

The EtherMeter can be used to enable a SCADA system to collect both water and gas meter totalization and instantaneous flow-rate — even simultaneously. An interesting application is the use of a single EtherMeter connected to an encoder-based water meter plus an encoder-based gas meter.  In the example illustrated below, a Sensus SR-II water meter and a Sensus R-275 temperature-compensated Read More →
