For example:
If the design flowrate is 6 T/H, then:
Test weight 60% = 6 t/h × 60% × 45 g/t/h
= 162 g
Test weight 80% = 6 t/h × 80% × 45 g/t/h
= 216g
Therefore the test weight should be between 162 and 216 g.
If an available test weight of 200 g is used, then:
Test rate = 200 g ÷ 45 g t/h
= 4.444 t/h
Perform the zero calibration as described in the Calibration section of the integrator manual.
After the completion of the zero calibration, a span calibration, as described in the integrator
instruction manual, can be performed with the test weight(s) applied.
Span
1. Install the calibration pulley to the bracket on the flowmeter housing.
2. Hang the test weight over the calibration pulley using the test weight cable.
3. Perform the span calibration as described in the calibration section of the integrator
instruction manual.
