Show 0 TYPE OF WATER METER the selection of the type of 0 meter to be employed in measuring the flow 0 of water through a pipe line should be based upon the consideration of the difficulties of installation stal lation permanency of operation accuracy of measurement and the cost of installation and maintenance tests to determine the practicability of employing thin plate orifices in pipe lines and the conditions most favorable for their use as measuring devices have been completed by the engineering experiment station of the university of illinois under the direction of R E davis associate in civil engineering and H H jordan assistant professor in general engineering drawing the tests were conducted with three sets of orifices of eight different diameters per set cut in 3 16 inch steel plates data were obtained from 4 inch 6 inch and 12 inch pipe systems respectively the results of these tests are given in detail in bulletin no entitled the orifice as a means of measuring flow of water through a pipe copies of bulletin no may be had without charge by addressing the engineering experiment station urbana illinois |
