procedure to commission a drum level transmitter



procedure to commission a drum level transmitter..

Answer / guest

1.Fix the transmitter on the process line and connect the
power supply.
2.Connect the impulse line to the transmitter.
3.Ensure level transmitter HP and LP main isolation valve
is closed.
4.Open the HP and LP valve and close the equiliser valve to
the transmitter.
5.Close the vent plug to the transmitter.
6.fill the water (condensate pot via) on LP side of the
transmittre impulse line.
7.Ensure transmitter display showing is zero.
8.If not showing zero,release the air lock (vent plug via).
9.Open the HP and LP main isolation valve.
10.Ensure the level transmitter working is normal.

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 =
