| Schematic diagrams of both types of demand meters and their registers are shown in Fig. 17-22. |

| Demand meters for two- and three-phase circuits are similar to the single-phase-demand meter, the dials being used to read the two- and three-phase demands. |

| Similar demand meters for measuring reactive volt-amperes and reactive volt-ampere-hours operate in a similar fashion, being basically watt-hour meters with the voltage displaced 90° by means of added reactances. |

| Recording Meters |

| Almost all the meters described above are fitted with recording mechanisms. A recording device, either spring- or motor-driven or motor- |
