Battery Care

•

The European Batteries Directive and equivalent legislation in other countries requires
that all batteries are disposed of correctly at the end of their working life. This means that
they must be collected and treated separately from other waste.

•

It is recommended to remove the battery from the battery compartment if the flowmeter
is not to be used for an extended period of time. Deep discharge of alkaline batteries
can result in the eventual leakage of battery electrolyte even from quality batteries and
can cause corrosion of the battery compartment terminals and potentially the flowmeter
printed circuit board.
