Flow-measuring device for the purpose of diagnosing the cause of rising water pressure in a closed water system

A flow-measuring device for measuring a rate of flow of a liquid comprising, in combination:

• a housing having a top and a bottom and defining a central opening, an entry at the top of the housing, and a central chamber, wherein the central chamber is connected to the entry by the central opening;
• a circumferential lip extending from the central chamber where the central opening meets the central chamber, wherein the circumferential lip is adapted to collect droplets of the fluid at a rate proportional to the flow rate of the fluid;
• an exit in fluid communication with the central chamber;
• a pair of metal elements each mounted in the exit, wherein the pair of metal elements are separated by a hoop distance and operatively connected to a sensor;
• and
• both metal elements are adapted to receive and be in contact with the droplet when the droplet falls from the circumferential lip for a contact time, and the sensor is adapted to sense when the droplet is in contact with both metal elements.
