Question 3 (3 points)

Level Tank

For the above system, "Water Level Tank", find the range of the pressure transmitter?

Where, A = 150”, B = 10”, and C = 5.

.

Question 3 options:

	0-140"wc
	0-150"wc
	10-145"wc
	0-145"wc

Answer 1

Considering the maximum water level height of A=150'' and Transmitter position inside the tank at B=10'' above the base level of the tank. The transmitter would only detect the pressure head above it which would be:

PressureMax= A-B = 150''wc-10''wc = 140''wc

PressureMin= 0 (Since there would not be any water head above the transmitter for water level at C or below it)

Range = PressureMax - PressureMin = 140''wc - 0

That is the option 0-140''wc.
