Conventional liquid level indicators

Unexpected or accidental oil leakages can occur in a transformer’s lifetime. Clear and visible indication of the oil or liquid level is provided by dedicated dials suitable for oil-filled transformers, on-load tap changers, conservator tanks, and other components.

Hitachi Energy's liquid level indicators give off an alarm if the fluid reaches the minimum or maximum preset values.
