The model evoQ4 is a popular magnetic flow meter manufactured by Honeywell (formerly Elster-AMCO); and it is available in pipe diameters 1.5-12 inch. Like many AWWA-style flow meters, the evoQ4 is available with several remote signaling options, including: Encoded and pulse signaling modules for the evoQ4 are detailed in the following Honeywell documents: HERE (pulse … Read More →
In certain industrial water meter applications, a pulse-per-volume output is required to provide signaling to a connected batching or telemetry system. When using a member of the electro-mechanical flow meter family from Neptune Technology Group (Tallassee, AL, USA), the traditional solution was to outfit the meter with Neptune’s Tricon/S register. The Tricon/S provided a visual … Read More →
You have an AMI-capable water meter, and you are quite satisfied with its ability to transmit revenue-grade readings into your system – but in certain situations, wouldn’t it be useful if two or more systems were able to collect the reading from the water meter? The patent-pending Model UDA “Universal Duplexer for AMI Systems” was … Read More →
The Boone IA Firmware is a customized EtherMeter firmware that was created to provide a simple solution to a customer who desired zoned leak detection. This EtherMeter version, which is now offered as an option at our eStore, signals an alarm annunciator when higher-than-normal flows are detected from a connected flow meter. In this project, the … Read More →
A new firmware version of the EtherMeter has been created that is tailored to transmit flow metering data over the Iridium Satellite Data Network. Iridium is a constellation of Low-Earth-Orbit satellites capable of receiving data from virtually anywhere in the world. Validation was successfully performed at a Water District in rural North Dakota. Value-added SCADA … Read More →
In instances where the pulse input signal is derived from a mechanical contact (eg reed-relay pulse signals from many gas meters), it may be necessary to install a “de-bounce” filter on the pulse-input wires to remove false pulses caused by bouncing and/or arcing contacts. The capacitor value is selected based upon the expected pulse duration. … Read More →
[2022 Edit: The technology in this article has been deprecated, due to our introduction of the Model EMP Signalizer™ and Model APK (and APK.PLUS) Analog Pulse Kit, which supplant the need for the equipment and techniques described in this article.] In most cases, EtherMeter users will collect flow rate data via the device’s digital Ethernet … 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 →
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 “E-Coder” is an excellent water meter register, manufactured by Neptune Technology Group, that features an all-digital LCD display activated and powered by an integral solar cell. The register as a whole does not contain a battery, and it is entirely powered by a combination of hydroelectric energy (water passing through the meter) and the solar cell. … 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 is the only known device that can calculate, transmit, and display rate-of-flow and totalization from all the major encoder-based water meters. And this fact can come in handy for a multitude of applications. For example, there are often occasions where bulk water users wish to visually monitor flow rate through a variable speed pump or … Read More →
A new application note has been posted to the support page of scadametrics.com. The note documents the procedures for programming a Sensus “ICE” register (index) for maximum metering resolution and EtherMeter compatibility. Maximized resolution improves the connected SCADA system’s ability to monitor realtime flow-rate and totalization from both water and gas meters. While it is preferable (and simpler) for the customer to … 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 →
A new application note has been published to scadametrics.com that details the steps required to connect an EtherMeter and a popular Koyo PLC using MODBUS/TCP. … 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 →
A new white paper has been posted to scadametrics.com. In this paper, methods are described for connecting a combination of water and gas meters to an automation network. Because Itron/Actaris offers encoder-type signaling, in the form of the “Cyble-Coder” technology — in both their water and gas meters — the Itron/Actaris models are emphasized in this article.
