Electronic meters display the energy used on an LCD display, and some can also transmit readings to remote places. In addition to measuring energy used, electronic meters can also record other parameters of the load and supply such as instantaneous and maximum rate of usage demands, voltages, power factor and reactive power used etc. They can also support time-of-day billing, for example, recording the amount of energy used during on-peak and off-peak hours.
LCD displays are preferred in meter applications because of their cost advantages and power savings. LCD Displays are much lower cost than VFD, TFT or LED displays. Also the power consumption of the LCD displays is much lower than the alternatives.
