Oil flow indicator (referred to indicator below) is the device to monitor and indicate the variation of oil flow in the oil circulation cooling system of transformer. Specifically, it is used to indicate whether the rotation of oil pump is correct, the valve is turned on, the pipeline is clogged. The relay will send an alarm signal to the control unit when the oil flow reaches the operating value.
