Abstract
A system and method for measurement of flow parameters in a sewer pipe that may be partially or completely filled. Flow parameters may include flow velocity, flow volume, depth of flow and surcharge pressure. Measurements are taken from a sensor head installed on the inside of the pipe at the top of the pipe approximately the larger of at least 1 foot or 1 pipe diameter upstream of a pipe opening. Flow velocity may be measured by two different technologies. The technology employed depends on whether or not the pipe is full. If the pipe is not full then flow velocity may be measured, for example, using a wide beam, ultrasonic, diagonally downward looking Doppler signal that interacts with the surface of the flow. If the pipe is full, then flow velocity may be measured using, for example, an average velocity Doppler sensor, a peak velocity Doppler sensor or an ultrasonic velocity profiler.
