meters including the items listed in 6.2.2 In lieu of performing additional tests to address those items, the manufacturer may provide data to show how their meter is affected by these items The Special Tests may include the following: — as per the manufacturers minimum upstream length with elbow in plane; — as per the manufacturers minimum upstream length with close coupled elbows out of plane; — as per the end user’s specific application requirements if it differs from the tests above Testi n g Proced u re The mandatory test procedure shall be as follows — The test points should cover the following velocities: 0.1 , 0.5, , 2, 5, 0, 20, 50, 00 ft/s (0.03, 0.1 5, 0.30, 0.61 , 5, 3.0, 6.1 , 5, 30 m/s) then at 50 ft/s (1 m/s) increments up to the maximum velocity or capability of the meter — Adjust the flow rate until stable and obtain readings as follows: — readings; — reading = data set = a minimum of 30 seconds of data with data point recorded per second Determine the standard deviation, average, and repeatability of the readings — Test should be run as follows ) Starting at the minimum or maximum point, run through the first three consecutive velocities gathering readings as described above 2) Drop back by one velocity point and perform a repeat (e.g 0.1 , 0.5, 0, repeat 0.5 if going up) The repeat point value should be within % of the initial run at that velocity point 3) Run through the next three velocities followed by another repeat point (e.g 2, 5, 0, repeat if going up) 4) Continue until all test velocities are covered — As noted previously, it is important that the tests are performed at a low pressure to mimic typical flare systems Additional testing, including ramping downward and testing at specific velocities of interest is discretionary 7 Test Faci l i ty Req u i rem en ts Au d i t Process In order to assure validity of tests performed following the testing protocols defined in this chapter, the laboratory or testing
