A flow meter has a span of 0-10,000 gallons per minute (gpm). What is the mA output at 5,000 gpm?
A. 8 mA
B. 12 mA
C. 16 mA
D. 20 mA
Answer:B
A flow meter has a span of 0-10,000 gallons per minute (gpm). What is the mA output at 5,000 gpm?
A. 8 mA B. 12 mA C. 16 mA D. 20 mA
Explanation: In the 4-20 mA current loop standard, the 4 mA corresponds to the minimum process value (0 gpm in this case) and 20 mA corresponds to the maximum process value (10,000 gpm here).
