5. A flow transmitter ranged 0 to 800 cc/min is tested by using a rotameter (visual flow indicator) in series as a reference standard. The fluid flow through a pipe is varied and both flow indications are recorded to test the transmitter against the rotameter. The results are shown below.
Input (%) Rotameter Reading (cc/min) Flow Transmitter Reading (cc/min)
0 0 0
25 200 180
50 400 360
75 600 540
100 800 720
