Abstract
The invention provides a method of verifying the health of a liquid level detection device, preferably a vibrating fork level switch, while the device remains in situ. The method includes, independently of the device, verifying if the fork tines are fully wet or fully dry. This step can be carried out by a further, independent, level measuring apparatus.
