Abstract |
A research and development program to develop a portable device which is capable of measuring wastewater flow in sewers was undertaken. This work consisted of an investigation of the theoretical approach to be used, laboratory investigations and experiments to develop design criteria, design and fabrication of two prototype units, and field testing and evaluation of these units. Measurement of the cross-sectional area of flow was done by the use of capacitor plates to sense the change in water level in the sewer pipe. The method selected to measure the velocity of the flow involved the timing of a heat pulse as it traveled down the pipe. Theoretical evaluations and laboratory experiments were performed to prove the mode of operation of the proposed gage. (Modified author abstract) |
