Use the AWWA M6 Manual
Ask the customer how much water they want to use
Variable, based on flow rate required
However much is needed to produce desired results

Question 24 of 38

How many tests are typically required for a single meter across different flow rates?

3 or 4, depending on the meter type
1 or 2, depending on the meter type
As many as needed to produce the desired results

Question 25 of 38

If you encounter questionable accuracy results (and have already double-checked both meter strainers), which of the following methods should you try next?

Re-run the test with a different tester
Re-run the test and decrease the water temperature

Question 26 of 38

How can you determine the crossover point of a non-OMNI compound meter?

Open the test valve to full and reduce flow until the pressure rises
Open the test valve to full and reduce flow until the pressure falls
Open the tester valve slowly until pressure rises–the rate indicates the crossover point

Question 27 of 38

What is the formula for testing a non-OMNI meter?

Meter under test volume divided by tester volume multiplied by tester accuracy from test tag.
Tester volume divided by meter under test volume multiplied by tester accuracy from test tag.
