corresponding to the average hourly rate of flow for the period since

the last preceding test, then any previous recordings of such

equipment shall be corrected to zero error for any period which is

known definitely but in case the period is not known or agreed upon,

such correction shall be for a period extending over one-half of the

time elapsed since the date of last test, not to exceed a period of

180 days.

installed and accurately registering; or, in the absence of (a);


(b) by correcting the error if the percentage of error is

ascertainable by calibration, tests, or mathematical calculation; or

periods under similar conditions when the meter was registering
