Abstract
A positive verification of fluid flow from a reservoir through a metering pump is provided by monitoring the downstream fluid pressure fluctuations caused in the fluid conduit by inserting a pressure sustaining valve in it. A pressure switch or similar device coacts with a pulse timer to monitor the periodic pressure fluctuations in the conduit. A lapse in the periodic pressure fluctuations for a specified time allows the timer to activate an alarm signal.
