what type of power does a wattmeter measure
Wattmeter The wattmeter is an instrument for measuring the electric power (or the supply rate of electrical energy) in watts of any given circuit. Electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.
Watt The watt (symbol: W) is a derived unit of power in the International System of Units (SI) defined as 1 joule per second[1] and can be used to quantify the rate of energy transfer. Power has dimensions of    M L  2   T  − 3   {\displaystyle {\mathsf {ML}}^{2}{\mathsf {T}}^{-3}} .

In dimensional analysis it is described by    M L  2   T  − 3   {\displaystyle {\mathsf {ML}}^{2}{\mathsf {T}}^{-3}} .[2]
Weigh station "Weigh-in-motion" technology allows heavy vehicles that do not exceed limits of weight (and size) to pass the scale, thus improving both freight and weigh scale operation efficiency.
