 Electrical Single-phase prepaid meters electricity and installed by a electrician is often used in homes or business where electricity is mostly used for general purposes  such as lighting and heating.

• Single-phase electric power refers to the distribution of alternating current in which all the voltages  of the supply vary in unison.
• Standard frequencies of single-phase power systems are either 50 or 60 Hz
• Single phase power availability varies in different countries. For example, in the UK a single-phase  household supply may be rated 100 Amps to 125 Amps. This may mean that there is little need for 3  phase electricity in a domestic or small commercial environment.

 Power stations supply three-phase electricity which is three times as much electricity along three wires as can be supplied through two wires, without having to increase the thickness of the wires.
Large buildings, shopping centers, factories, office blocks, and multiple-unit apartments generally have three-phase electricity.
The most important class of a three-phase load is the electric motor. Such motors are applied in industry for pumps, fans, blowers, compressors, conveyor drives etc. Large air conditioning equipment (units above 8.8 kW cooling capacity) use three-phase motors for reasons of efficiency and economy. Resistance  type heating such as electric boilers may be connected to three-phase systems. Electric lighting may also be similarly connected. These types of loads do not require the revolving magnetic field characteristic of three-phase motors but take advantage of the higher voltage and power level usually associated with three-phase distribution. we have the right prepaid meters for you intalled by registered electrician

 Typical prepaid meters such as water meters are mechanical flow meters. Commonly used meters are piston meters, also known as rotary piston or semi-positive displacement meters. The piston meter operates on the principle of a piston rotating within a chamber of known volume. For each rotation, a count for the amount of liquid is computed.
Various prepaid water meter are available depending on the nominal bore (NB). NB (nominal bore) also refers to Nominal Pipe Size (NPS). The Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures also indicating the required wall thickness.
The European designation equivalent to NPS is DN (nominal diameter) in which pipe sizes are measured in millimeters. Based on the pipe size, the outside diameter (OD) and wall thickness can is obtained by use of reference tables.
