i/p converter always for supply pessure from 3~15 psi only !! And from where this converter bleed the air.
2 5519My flow transmitter range is 0-1000mmwc.DCS range is 0- 100m3/hr.What is correspond out put in terms of milliamps if my flow is 65m3/hr
4 9673Coriolis flow meter coil supply is 24vdc but why still we given 230ac for this transmitter let me explained detailed review please
1 4841Q1: 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 =
19911)why we are using mostly Ultrasonic Flow meters to measure flow, rather than Radar waves? 2)why we are using Ultrasonic waves and Radar waves to measure the Level?
NTPC,
1 4776Air pressure in a pressure vessel can rise or fall at up to 2.5kpa/s.The pressure is sampled every 0.5 seconds.If range of the the pressure indication is 0 to 1500 kPa, what is the max value of the error due to sampling in % of Span
2 4379a pressure transmitter with a range of 0 to 2500kpag has a specified accuracy of 0.5 % of span.It is to be calibrated using a comparison gauge to have an accuracy of 0.1% of span.The comparison gauge has a range of 0 to 3000kpag What is the accuracy ratio? is this ratio acceptable?
