DN150 Die Casting Iron Transformer Oil Indicator Wholesaler

Oil flow relay (hereinafter referred to as the relay) is the device to indicate oil flow variation in the forced oil circulation cooling system of transformer. It is used to monitor the oil pump operation in the forced oil cooling system, whether oil pump rotation is correct, the valve is turned on, the pipeline is clogged, etc. When the oil flow reaches the motion oil flow or reduces to the return oil flow, the relay will send an alarm signal.
