Fig^ure 35. — Calibration of flowmeter — sample copy of record for meter ^1179 on June 21, 1966. The meter, with 

 others on a board (see Fig. 33 and 34), is pushed over a measured distance at a number of speeds, in this instance 

 13 runs at approximately 15 to 40 sec. The meters per revolution are plotted against revolutions per second for 

 part of the calibration curve shown in Figure 36.
