In 2011, SCADAmetrics introduced the Radio-Read Filter — the device that enables two AMR devices to read a single water meter simultaneously.  This instrument serves a vitally important function in situations where both the water seller and buyer are interested in tracking water consumption. One example might be a utility-owned water meter in a commercial building.  In such a case, the water 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 →

Many petroleum industry flow metering applications feature the use of magnetic-pickup-type turbine meters.  (See Figure 1 below.)  Internally, these meters feature a steel turbine that rotates past 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, whose frequency and amplitude both increase as Read More →

When totalizing the total accumulated flow through a non-absolute-encoder flow meter, it is generally preferable to interface with a pulse-per-volume signal (eg. 1 pulse per gallon). However, certain flow meters only offer a 4-20mA signal that is proportional to rate-of-flow. Examples include certain Parshall Flume-Type Wastewater Flow Meters, Differential-Pressure Flow Meters, WH Power Meters, and many Read More →
