At times, it’s necessary to splice a meter’s integral signal cable with an extension cable to increase the overall cable length.

For splice hardware, I recommend the UY2 Scotchlok connectors by 3M:  Datasheet Link

For 3-conductor extension cable, I recommend 5521FE cable by Belden (Part No. 5521FE 008 1000): Datasheet Link.  Note that this Belden cable has three (3) solid, 22-gauge, copper conductors with color-coded insulators (RED, BLACK, WHITE), an outer foil shield and a drain wire.  This cable is riser-rated (CMR).  The drain wire should be tied to ground on only one end (preferably the control cabinet end).

For 4-conductor extension cable (for certain Radio-Read Filter applications), I recommend 5522FL cable by Belden (Part No. 5522FL 002 1000): Datasheet Link.  Note that this Belden cable has four (4) solid, 22-gauge, copper conductors with color-coded insulators (RED, BLACK, BLUE, BROWN), an outer foil shield and a drain wire.  This cable is riser-rated (FPLR). The drain wire should be tied to ground on only one end (preferably the control cabinet end).

An alternate 4-conductor extension cable that features stranded conductors (for certain Radio-Read Filter applications) is the 5502FE cable by Belden (Part No. 5502FE 008 1000): Datasheet Link.  Note that this Belden cable has four (4) stranded, 22-gauge, copper conductors with color-coded insulators (RED, GREEN,BLACK,WHITE ), an outer foil shield and a drain wire.  This cable is riser-rated (CMR). The drain wire should be tied to ground on only one end (preferably the control cabinet end).  However, keep in mind that the other solid conductor-type cable will likely work better with Scotchlok splicers.

All of the above hardware may be purchased from Newark Electronics or other electronic supply vendors.

The evoQ4 MagMeter by Elster-AMCO offers three (3) SCADA signal connection methods:

  • Elster-AMCO encoder protocol (K-Frame)
  • Sensus encoder protocol
  • Pulse-output

The EtherMeter is capable of interfacing with each of these methods.  However, this article will focus for now on the Elster-AMCO protocol.

Connecting an Elster-AMCO evoQ4 MagMeter to an EtherMeter is straightforward.  First, the Elster-AMCO protocol encoder module should be installed onto the meter:

After the module is successfully installed, follow these simple steps:

1. Strip away a couple inches of outer cable jacket, exposing the three inner conductors, and connect them to the EtherMeter.  When using meter channel #1, connect according to the following key: WHITE (Terminal 14), RED (Terminal 15), BLACK (Terminal 16).

Alternatively, when using meter channel #2, connect according to the following key: WHITE (Terminal 17), RED (Terminal 18), BLACK (Terminal 19).

Apply power to the EtherMeter, and watch the EtherMeter auto-detect the MagMeter:

Connecting an Elster-AMCO (ABB-Kent) ScanCoder water meter register to an EtherMeter is straightforward.

Just follow these simple steps:

1. Expose the communication wires by cutting the cable short of the ERT communication adapter:

2. Strip away a couple inches of outer cable jacket, exposing the three inner conductors, and connect them to the EtherMeter.  When using meter channel #1, connect according to the following key: BLACK (Terminal 14), RED (Terminal 15), BARE-SHIELD (Terminal 16).

Alternatively, when using meter channel #2, connect according to the following key: BLACK (Terminal 17), RED (Terminal 18), BARE-SHIELD (Terminal 19).

Apply power to the EtherMeter, and watch the EtherMeter auto-detect the meter register:
