i need some objective type questions in instrumentation
dear friends, i have seen flow as the selection critriea in presure guage (bourdon tube) and i would like to know what is the relation between flow and performance of pressure guage other parameters i found in the data sheet are pressure max. 1ksc temperature max. - 50 deg c line size - 80NB operating range - 1ksc pr. guage range - 0-2 ksc thank u,
Drum level tx with GP4 with zero elevation:7300mmh20 on HP and 8050mmh2o on LP as range but on commissioning the tx readiing is max,Why this reading?

What is furnace draft control?
Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =
