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: Sensus-Protocol 8-Digit
- Encoded: Sensus-Protocol 6-Digit
- Encoded: Elster-Protocol 6-Digit
- Pulse-per-Volume
- Encoded: Sensus-Protocol 8-Digit + Pulse-per-Volume
Encoded and pulse signaling modules for the evoQ4 are detailed in the following Honeywell documents: HERE (pulse and K-Frame encoded) and HERE(Sensus encoded).
SCADAmetrics is pleased to report that our broad line of flow metering instrumentation has well-established compatibility with the Honeywell signaling modules; and it is well-poised to add value to challenging evoQ4 metering applications — especially with respect to SCADA connectivity and Visual Remote Displays.
1. Concurrent SCADA and AMI
The following illustrates how an evoQ4 can provide basic SCADA signaling (4-20 milliamp, pulse-per-volume, flow switch), plus AMI signaling (Sensus protocol). Excellent for custody-transfer stations and commercial buildings. Design Basis: Model APK Analog-Pulse Kit:
2. Concurrent SCADA, AMI, and Remote Display
The following illustrates how an evoQ4 can provide basic SCADA signaling (4-20 milliamp, pulse-per-volume, flow switch), AMI signaling (Sensus protocol), and a Remote Wall Display. Excellent for custody-transfer stations and commercial buildings. Design Basis: Model APK Analog-Pulse Kit and Model TMD TheMeterDisplay:
3. Advanced SCADA
The following illustrates how an evoQ4 can provide advanced SCADA signaling (Modbus, Allen-Bradley EtherNet/IP). Excellent for custody-transfer pumping and valve stations where revenue-grade accuracy is of paramount importance. Also excellent for military bases and educational facilities. The addition of a model SDA or SDAW Duplexer (not shown) may be added if concurrent AMI connectivity is desired. Design Basis: Model EM.100 EtherMeter:
4. Basic SCADA
The following illustrates how an evoQ4 can provide basic SCADA signaling (4-20 milliamp, pulse-per-volume, flow switch). Excellent for well and pumping stations, as well as commercial buildings. Design Basis: Model APK Analog-Pulse Kit:
5. Visual Batching, Visual Rate-of-Flow, plus SCADA Outputs
The following illustrates how an evoQ4 can provide basic SCADA signaling (4-20 milliamp, pulse-per-volume, flow switch), along with an always-ON operator flow and batch display. Excellent for well and pumping stations. Design Basis: SCADAmetrics Model APK.PLUS Analog-Pulse Kit, Plus:
6. Dual-AMI Connectivity
The following illustrates how an evoQ4 can provide AMI signaling to two separate systems. Excellent for custody-transfer stations, where both the water buyer and seller desire meter connectivity to their separate respective AMI systems. Design Basis: SCADAmetrics Model UDA Universal Duplexer for AMI:
7. Concurrent AMI Connectivity and Remote Visual Display
The following illustrates how a model TMD display can work with an evoQ4 to provide AMI signaling to the water utility, while concurrently providing a visual remote display whose reading is a perfect match to the evoQ4 register total. Furthermore, if an 8-digit Sensus-protocol encoded module is used, then display of rate-of-flow (gpm,lpm) is also available. Excellent for utility-owned water meters at commercial and industrial buildings, where the building owner desires a meter reading without requiring entry to a vault or confined-space. Design Basis: SCADAmetrics Model TMD TheMeterDisplay:
8. Retrofit SCADA Connectivity to AMI-Connected Meter
The following illustrates how a model EMP Signalizer display can be applied to an evoQ4 that is outfitted with an encoded output module to provide basic SCADA signaling, while preserving the existing AMI signaling to the water utility. The SCADA signaling is in the form of a pulse-per-volume output. Furthermore, if an 8-digit Sensus-protocol encoded module is used, then a 4-20 milliamp SCADA signal is also provided. Excellent for utility-owned water meters at commercial and industrial buildings, where the building owner desires a meter reading into its BMS system, without requiring the installation of a new water meter, or without interfering with the utility’s AMI system.
