what is the working principle of vortex flowmeter
Answer Posted / yugesh shah
Working principle is piezo electricity..
When liquid or vapor passing from vortex meter at that time sensor activate and produce mechanical distoration so at the end emf produces.
In the between of the metal body there is a piezo electric crystal, amplifier in upper side and analog meter in other side...
Both side flange in line of vortex meter
Emf produce and given to amplifier
There is 24v dc to operate an amplifier
Output of amplifier connected with i --> p
Produce 0.2 to 1.0kg/cm2
Given to recorder or controller
Output of controller given to control valve
From that changes in output of controller, valve changes its position as per set point

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 =
