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 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 →

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.

When connecting a Sensus Omni Meter (T2, C2, R2, or F2) to an EtherMeter, it is important to connect to the proper Omni cable.  A potential point of confusion is that the Omni meter features two identical, integrated cables.  In order to clarify the wiring, an application note (Application Note #6) has been published on scadametrics.com with wiring Read More →
