A pressure transmitter with a range of 0-100 bar.The accuracy of the instrument is 1% of upper range value? The pressure indicating transmitter is showing the system pressure is 50 bar. b. When you include the error, what is the minimum possible pressure in our fuel gas system? i. 49.5 bar ii. 49 bar iii. 1 bar iv. 0.5 bar We want to change the filter cartridge. We must depressure the fuel gas system. c. After we depressure the system in preparation for maintenance, the transmitter displays a pressure of +0.1 bar. At this time, what is the possible range of pressures in our fuel system? i. +0.099 to +0.101 bar ii. 0 to +0.2 bar iii. -0.1 to +0.3 bar iv. -0.9 to +1.1 bar
