YWZ Series Oil Level Gauge
The YWZ series oil level gauge combines the oil level testing device and oil temperature testing device of the transformer oil tank. The float part drives the oil level indicator through a transmission part and magnetic coupling; the bimetallic temperature sensing rod converts temperature changes into pointer rotation for on-site observation.
