Standard Material Test Protocol

Test Equipment Setup: See below for drawing.

Test Protocol:

I. Equilibrate: Material batches of 10 to15 gallons will be run through meter 10 times to equilibrate the unit. Equilibrate means allowing the material to build up on the measurement surfaces to a point where the material can not build up any further.

II. Calibration: Run five 10 to 15 gallon batches of material through the meter and record the meter�fs mass flow output versus the weight of each batch falling into a weighing bucket as measured on a certified scale. Take the average differential between meter�fs mass flow output and the scale readings and determine the calibration voltage offset. Adjust the calibration voltage accordingly.

III. Test: Run five 10 to 15 gallons batches of material through the meter at the desired rate(s) and record the meter�fs mass flow output. Record the weight of each batch falling into a weighing hopper as measured on a certified scale.

IV. Calculate Accuracy as a percent of Reading. Calculate Standard Deviation.

Test Costs (Customer to check off one of the following):
Testing at one flow rate; we match the percent of volumetric flow, full scale, for the test meter that the customer�fs actual sized meter will see. Test Charge: 0 *

Testing at two flow rates; (75 to 100%, and 30 to 50% of volumetric flow). Test Charge: 0 *

Testing at three flow rates; (80 to 100%, 50 to 70%, and 20 to 40% of volumetric flow). Test Charge: 0*

Video tape the test; a VHS format tape will be furnished: 0.

* If the customer decides to purchase a meter(s) within 90 days of the test, the test charge, less 0, will be deducted from the purchase of the first meter.
