Portalevel Standard

The Portalevel® Standard uses ultrasonic technology to identify the interface between liquid and air in any single skinned container. It has none of the user problems associated with radioactive liquid level indicators which require dedicated training, storage, Health & Safety documentation, and transportation. It also replaces the traditional means of verifying liquid levels by dismantling and weighing in which the system may be closed down or disconnected, risking potential damage in so doing and involving considerable time, expense and inconvenience.
