There are different types of flowmeters according to their principles which are listed below. (1) Mass flow meter (2) Magnetic flow meter (3) Vortex flow meter (4) Thermal mass flowmeter This flowmeters are often used in the chemical industries,petrochemical industries,refinery etc. Now,Brifely explain the principle of different types of flowmeter. (1) Mass flow meter Mass flow meter works on "Coriolis principle" which is states that it contains a vibrating tube in which a flowing fluid causes changes in frequency,phase,shift and amplitude. The output is carried out on pc-board and the output is directly proportional to the mass flow rate. This flowmeter is most accurate and reliable. This flowmeter consist a two tube and when the fluid flow in this tube,it is oscillate symmetrically and sensor sense a signal and the result produced in the form of sinewave. As shown in fig,there is a three parts,(1) Pick up 1 (2) Pick up 2 (3) Driver. The

What is instrumentation and control?

-
      What is instrumentation and control ? Instrumentation and control was two different terms. This both term play a significant role in chemical,agrochemical,petrochemical,dairy,food industries etc. "Instrumentation" means,which gather information from the field. "Control" means,to changing the field parameters like flow,pressure,level,temperature. Instrument which is mounted in the plant to gather data from the field in which different types of instrument is used like valves,flowmeters,pressure transmitter,temperature transmitter,level transmitter etc. By using control system or controller we can control or changing the field parameters. In large manufacturing industries DCS (Distributed control system) is used and in small scale industries PLC (Programmable logic controller) is used. The goal of an IC engineer is to improving productivity,optimization,stability,reliability etc. A IC engineer is responsible for installing,designing,developing,managi
