some guestion about volum corrector

[coclurcool]

Hi, everybody:
I am designing the gas volum correcteor, which is used to adapt to the turbin gas meter. But I can't select the appropriate chips and ciucuts.Help me! Thanks!

You have to know what it is that you are trying to do. Since we don't know what you are trying to do, we can't help. Apparently, you know something about turbine meters, but I don't.

which chips ?

 

[coclurcool]

yes,you are right ! Now ,I will expatiate on the question in detail. First of all, the turbine gas meter is used to log the volume of the gas that flowing through the meter. You know , the pressure and the temperature of the gas are variational continually. So I want to collect the pressure and temperature, then utilize the equation( p*v/T = C(constant) ) to get the volume of the gas in the condition of the standard status ( p=0.103Mpa,
T=20+273.15K). Now I don't know how to collect the temperature and pressure. In addition ,the temperature sensor I will use is Pt500.
Could you help me ?
Thanks!

The PT500 is just a resistor, so you need an ohmmeter circuit. For the pressure sensor, go to www.digikey.com and put "pressure sensor" into the search box. There are hundreds to choose from.
