The Honeywell (Elster) evoQ4 is a very popular magnetic flow meter in use throughout North America. It is available with an Absolute Encoder Output signal, pulse signal, or both. At time of purchase, the AMR encoder signal may be specified as either “Elster K-Frame” protocol or “Sensus” protocol. If you would like to connect an … Read More →
SCADAmetrics is pleased to introduce the B202-v.108 Modem — a new release of our non-proprietary modem OEM module that is targeted for use within Radio Telemetry / SCADA Systems! This new modem constitutes a major re-design of our first-generation modem, the B202-v103; and it offers the following new features: 100% compatibility with existing telemetry/SCADA systems … Read More →
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 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 →

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: https://scadametrics.com/PDF/App_Note_014.pdf Note that the Sensus … 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: Latest EtherMeter: … 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 →
In response to customer requests, pulse-based batching capability has been added to the EtherMeter. This new ability will be included on all future EtherMeter shipments dated 01 Feb 2010 and beyond. In most municipal water applications in which a pulse-based water meter is used, the pulse count is generally preferred to totalize without reset. However, … 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 →
