摘要
In order to measure water flow in sewer systems or other tubes, a sensor ring is inserted into a pipe with capacitive sensors at discrete levels along a circumference of the pipe. Speed is measured by heating up a resistor and measuring the rate at which heat is extracted from the resistor by the flowing liquid.
