YZF-90 Series Pointer-type Oil Level Gauge
The YZF series pointer-type oil level gauge (abbreviated as oil level gauge) is an oil level testing device for transformer oil storage tanks. Its main structure includes: floating ball part, transmission part, magnetic coupling, indication part, and alarm part. The float part drives the indicator part through the transmission part and magnetic coupling to indicate the oil level, and finally indicates the oil level on the dial through the pointer. It also sends an alarm signal at the lowest and highest oil levels, achieving the purpose of remote monitoring.
