Waste water assessment

摘要

Waste water assessment apparatus, a method and a computer program are provided. The waste water assessment apparatus comprises: transceiver circuitry configured to transmit a microwave signal and to receive one or more reflections of the microwave signal; and processing circuitry configured to process the one or more reflections of the microwave signal to determine one or more characteristics of waste water flowing through a conduit.

主权项

1. An apparatus, comprising:
transceiver circuitry for periodically transmitting microwave signals through a wall of a closed conduit channeling waste water away from property and for receiving reflections of the microwave signals, from within the closed conduit, that have passed through the wall of the closed conduit; processing circuitry configured to:
process one or more of the reflections of the microwave signals to determine a distance between the transceiver circuitry and a surface of the waste water flowing in the closed conduit;determine that the determined distance has been constant for a period of time;distinguish between a constant determined distance corresponding with a steady flow of waste water in the closed conduit and a constant determined distance corresponding with a blockage in the closed conduit by determining that there is the blockage in the closed conduit if the period of time is longer than a threshold period of time; andcause a user to be alerted as to a presence of the blockage in response to the processing circuitry determining that the determined distance between the transceiver circuitry and the surface of the waste water has been constant for the period of time longer than the threshold period of time.
