A test weight is a calibration reference used to simulate a material impact force (test rate) on

the flowmeter sensing plate during the integrator span calibration. The test weight is also

used to perform a test to verify that the flowmeter sensing head is level.

The test rate should be 60 to 80% of the system design rate.

To determine the test rate produced by a specific test weight, calculate:

Alternatively, to determine the test weight required for a specific test rate, calculate:

Note

*For WF350 flowmeters, use 80 grams (instead of 65 grams) when calculating Test Rate or

Test Weight.

Example

If the test weight used with a WF330 flowmeter is 500 grams:

Note

Use metric tons per hour (t/h) or short tons per hour (STPH) as applicable for TPH.
