Flow meter
(OP)
Does anyone have info about flow meter which have input "WHAT VOLUME WE NEED TO FEED IN BATCH REACTOR " ???
e.g. i need 100kg or 100m3 is set point on meter , after feeding fluid supply pump auto stop.
pl do needful ( provide link for proper deal)

I am having difficult determining what your question is. If you are having difficulties with the language, you might go to forum1529: Translation Assistance for Engineers and ask the question in your native language and see if the helpful people over there can help you put it into a form that will lead to the answer to the question you are asking.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.
The plural of anecdote is not "data"
RE: Flow meter
i need info about flow meter.... which has future of measuring mass of fluid required ....
e.g. if i need batch of 100kg fluid, then on flow meter i will set 100kg . that much liquid should discharge by pump.
Understood dear??
RE: Flow meter
We normally do this with load cells beneath the receiving tank. Measure weight as it fills, and turn off the supply at a time that allows the fluid still in the pipe downstream of the valve to complete the batch load. This correction we call in-flight adjustment.
I do not know of a flow controller that will do this as a stand-alone device in the way that you want to use it. I would have a PLC monitor the flow transmitter and take the action to start and stop flow to achieve the batch weight. Note that you will still need to account for in-flight quantities downstream of your valve.
I have installed one similar system in the US in a case where load cells are not feasible. There are manufacturers of totalizing flow transmitters such as Data Industrial, Flowline, Fluidyne, Thermo Scientific.
Best to you,

RE: Flow meter
You would need a small PLC to start and stop your delivery system, but again there are many vendors able to supply a total package. What you describe is similar to a tanker loading system where so long as you want to measure volume and not mass, you can just punch figueres into a meter head and it will count down and stop flow automatically.

There are also separate electronic batch controllers that take the flow rate signal from the flow meter and have the buttons to easily enter batch preset values, reset, and what-not.
RE: Flow meter
i.e in 1 ton reactor if we have to feed 500 kg or 500 liter of water , which type of arrangement or flow transmitter ll help us ???
pls mention link if any company is supply that type of arrangement.
Thanks all above for giving good reply.
RE: Flow meter
Will the meter always be wetted (liquid filled) or will it run empty from time to time?
Good luck,

Also, the safety of your chemicals come into play. If you accidentally overfill, does everything go BOOM? Simple might not be the best in that case, you may need a parallel manual and automatic approach using new and old technologies.
