I’m seeking help from everyone – how should the actual energy consumption of centrifugal oil pumps be calculated?

There are 4 oil transfer centrifugal pumps, 2 with an axial power of 110 KW and 2 with an axial power of 90 KW. Previously, two pumps were in operation: a high-power pump used as the power-frequency pump, and a low-power pump used as the variable-frequency pump. Now the oil volume is less than before; two low-power pumps are used, operating one at normal capacity and the other in reduced capacity. I want to know how much electricity has been saved – how should I calculate it?

Reduced power (kW) multiplied by time (hours)

Is there no ammeter? Just look at the readings on the gauge to compare and you’ll get the result
