ABSTRACT:
The flow of liquid along a conduit or over a weir is measured by means of temperature-sensitive components positioned in vertically spaced relationship so that the number of components in contact with the liquid depends on the depth thereof. Thermal energy is supplied to the components in such manner that the components out of contact with the liquid are subjected to a substantial temperature increase. The components are periodically heated and examined after each period. Those of one temperature state are counted to indicate the depth of liquid and hence the flow rate.
A count linearly related to the flow in a given conduit or weir can be achieved.
