Remote register that counts pulses from a transmitting energy meter and repeats its reading at another location.

## In plain English

### What does Energy meter repeater mean?

An energy meter repeater has no measuring inputs of its own. It counts pulses from a transmitting meter and displays the resulting energy at a control room or tenant panel, so on the drawing it connects only to a signal circuit rather than to CTs and VTs.

### A simple example

Because it counts pulses, the repeater can drift from the master meter if pulses are lost or the supply is interrupted. The symbol does not show whether it has non-volatile memory or how it is reconciled with the master, which matters if the repeater is used for billing.

### What the drawings help you do

Confirm the repeater has no direct measuring inputs. Check the pulse weight matches the transmitting meter. A repeater counts pulses from another meter; a summation meter adds pulses from several meters.

### Terms

- Normally open / normally closed: The contact state in the normal condition defined for the drawing.
- Signal: Electrical information passed between devices, rather than necessarily the main power supply.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

An energy meter repeater has no measuring inputs of its own. It counts pulses from a transmitting meter and displays the resulting energy at a control room or tenant panel, so on the drawing it connects only to a signal circuit rather than to CTs and VTs.
Because it counts pulses, the repeater can drift from the master meter if pulses are lost or the supply is interrupted. The symbol does not show whether it has non-volatile memory or how it is reconciled with the master, which matters if the repeater is used for billing.

## How to read it

- Confirm the repeater has no direct measuring inputs.
- Check the pulse weight matches the transmitting meter.

## Information to show or reference

- Reference the master meter
- State pulse weight
- Show signal supply

## Important distinction

A repeater counts pulses from another meter; a summation meter adds pulses from several meters.
