If a differential pressure transmitter is calibrated for 0~2500 mmH2o and transmits a 4~20mA dc signal. The transmitter is placed across an orifice plate which is sized to create 2500 mmH2o differential at 5000m3/Hr a) what is the flow rate when the transmitter signal is 13.0mA DC? b) what is the signal output of the transmitter when flow rate is 2500 m3/Hr ?

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
