In this experiment, input heat flux is given to the evaporation region by using variac and can be measured by wattmeter. The power supply was turned on and the power incremented at this point in the tests, it took approximately 50 to 90 minutes to reach steady-state.
power meter (wattmeter) (according to the technical specifications) 2 units, 19 200 byn3.
These instruments make true power measurements using matched voltage and current input circuits for each wattmeter. They have the capability to make single phase, three phase-three wire, and three phase-four wire power measurements.

The second feature is the concept of a virtual wattmeter using the BACnet Accumulator standard object type indicating power consumption allocation to each indoor unit in the VRF system.
The inlet and outlet water temperatures measured with calibrated thermocouples, flow rates are measured with a laboratory-grade turbine flowmeter, and power is measured with an isolated true power wattmeter. A schematic of the hydronic network is shown in Figure 7.
The power consumption of the mill was measured using a Weston Wattmeter (ac and dc, model 310).
To ensure continuity between the new switched-coupler measurement system and the older, low frequency Bramall system, [8] comparison measurements were performed on a feed-through wattmeter. Figure 10 shows how these two systems compare at 30 MHz.
Cutting-power consumption was measured with a digital three-phase wattmeter and a pen recorder.
The input electric power to the compressor was measured by a Wattmeter with an uncertainty of [+ or -]5 W.
