An instrument which indicates the amount of electric current supplied to a circuit is known as a watt meter. In the earlier days, this instrument was used only by professionals but today a variety of meters are available which is both easy to use and relatively cheap. It is usually used to measure the amount of electric power used by an electrical appliance and to calculate the electrical costs.
Watt Meter- The Different Types and Uses
The measurement is usually indicated in watts. There are mainly two types of meters- the analog and the digital meters. The analog meters are also known as the ammeters. It includes a compass needle and a scale indicator. This was in fact the first device used in laboratories by scientists of the earlier days.
Digital watt meter: The electronic meter displays the readings on an LCD. It is considered to be far more accurate and faster compared to the analog meters. It has the capability to measure even the slightest change in the power consumption. The digital meters are more easy to use at home. Today there are a variety of electronic meters which are in-built with a number of features.
Portable meter: Another type of meter is the portable watt meter which can be used for on-site jobs. It can be carried around easily by electricians for the purpose of monitoring the flow of current supply to a unit.
Audio watt meter: These meters can be attached to the amplifier to measure the voltage transferred from the amplifier to the speakers. These meters can be bought from authentic online stores listed in the business portals.
Professional meters: These meters are among the most commonly used meters seen outside homes and apartments. It is usually fixed by the power department to measure the total electrical energy consumed by the households. The reading on the device will help the officials to calculate the amount of power consumption.
Meter with plugs: There are meters that can be plugged-in to the appliance to measure the power consumption. This watt meter is one of the most useful meters as it helps in detecting electrical problems related to the appliances. Abnormal power consumption can also be detected with the help of the plug-in meters.
Things to Consider Before Purchasing a Meter
Authentic websites: As there are a number of online stores that supply these meters, it is quiet important to choose an authentic website that sells reliable products.
Specific voltage range: Each instrument is rated for a specific voltage and any excessive amount of current can damage the instrument. Therefore it is important to choose equipments which can be used to measure multiple voltage values.
Reliable manufacturers: It is also important to purchase these meters from reliable and authentic manufacturers. Most of these meters are available with a number of advanced features these days.
A watt meter is one of the most useful equipments that can be utilised to measure the overall power consumption. So it is important to purchase equipments which are in-built with a number of attractive features.
