Penlon, Ltd has identified the potential for the premature failure of a component in some Electronic Flowmeter sensor display unit PCB assemblies.

Penlon Limited sent a Technical Bulletin dated November 22, 2011, to all affected customers. The letter identified the product, the problem, and the action to be taken by the customer. As a precaution a field upgrade part was released that required all existing PCB assemblies to be removed and the updated item installed. The old PCB must be returned to Penlon with the serial number of the affected machine. The required replacement parts were included with the technical bulletin.
