(b) The system used by Wongsugeh Sdn. Bhd for maintained close tank water level is illustrated in Figure Q2(b). (i) Established linear equation to represent the relationship of electrical signal produce by Differential Pressure (DP) with close tank water level (H2). (5 marks) (ii) Test linear equation established in Q2(b)(i) to evaluate the correctness of equation in representing the relationship of electrical current produce by differential Pressure with H2. The test can be done by choosing minimum and maximum value of H2. (4 marks) (iii) Estimate close tank water level H2 when pressure measured by Differential Pressure (DP) is equal 20000 PA (pascal). (5 marks)
Maximum level H2 8 meter Minimum level P(gas) S=9910 N/m3 Wet Leg Н1 1.2 meter Figure Q2(b) HP Dry Leg Dry Leg 4-20mA LP Differential Pressure (DP) Transmitter
