Abstract
A tamper-proof cover for a fluid flow monitor comprises a guard portion at least partly disposed about the monitor when the cover sealingly engages the fluid system in which the monitor is disposed. Preferably, the cover comprises an assembly including a plate fixed to the cover of the flow monitor to seal the interior of the device. Access to the monitor and alarm or actuator circuits disposed therein is impeded by the assembly so long as the cover seals the fluid system, and access thereto requires breaching the fluid system by removing the cover.
