Magnetic Oil Level Gauge (Indicator)are most commonly fitted on conservator of Power/Distribution Transformers.These Gauges give a visual indication of oil level and provide Alarmfacility at the desired level.Float movement due to rise and fall of oil level gives rotary movement to indicating pointer through bevel gears and magnets.General:-This gauge measures the contents of liquid inside a static tank and continuously indicates the contents on its calibrated scale. It has numerous applications but in the transformer industry for visual indication of oil contents inside the conservator's vessel, this gauge is most popular. Even electrical contacts are also provided to establish indication on the remote mode of abnormal position.
