Key facts about UTI’s
- UTI meters are portable liquid level gauges used to measure the amount of hydrocarbons and chemicals in a ship’s tank.
- UTI devices are used to measure the temperature and oil-water interface on tanker vessels using a sensor probe attached to a measurement tape.
- They comprise of a sensor probe, measurement tape, display unit and winding drum.
- The measurement tape length can vary from 15m to 40m and temperature range of -40°C to 110°C depending on the manufacturer.
- An annual shore service is advised to ensure that the UTI is in good order and has accurate measurements.
- They can be OPEN (Restricted) or CLOSED type. Closed type offers a gas tight body to prevent hazardous gases escaping from the measurement tank.
- Conversion fittings for UTI’s can be purchased to enable existing deck fittings to be used with a different UTI manufacturer.
- All UTI’s have earth grounding capabilities for safety implications.

- Crude Oil Tankers
- Clean Product Tankers
