5203 |a"A theoretical analysis complemented by experimental measurements was used to examine the behaviour of float activited water level recorder systems when used with the Stevens A-71 recorder. The equations developed can be used to predict measurement errors for any type of float type recording installation. The results show that for typical Water Survey of Canada installations, errors in measuring water levels can be kept to less than 3mm (0.01 ft.)"--Summary, page iii.
