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. In many instances, it is desirable to connect Read More →

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 2012, SCADAmetrics introduced the Model 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 analog telemetry radios, including models from Ritron, Tecnet, MDS, and RF Neulink, and Calamp. An interesting application is the use of Allen Bradley MicroLogix Read More →

Many industrial flow metering applications feature the use of Insertion-type paddle wheel sensors.  (See Figure 1 below.)  Internally, these meters feature a paddle wheel that rotates in the near vicinity of a magnetic pickup, similar in principle to a string pickup in an electric guitar.  The signal output from this type of meter is a low-level sine wave, Read More →

Telemetry, SCADA, and Building Automation System Integrators have wrestled for decades with totalization errors associated with pulse-output flow meters. The EtherMeter was designed to eliminate these errors.  We call the result: Revenue-Grade-Accurate Flow Metering. By leveraging absolute-encoder AMR technology — which is offered as a low-cost option by all of the major AWWA-type water meter manufacturers — the Read More →

In order to track and minimize utility costs, a growing number of forward-thinking, modern factories have initiated efforts to monitor utility usage in realtime — including electricity, water, and natural gas. And such monitoring does not only occur at the utility-owned meters, but within the factory itself so that a breakdown of the utility costs 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 →

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 →
