Measuring gas flow

In the factory i work for, many gas flows are measured. All flowmeters are vortexmeter and near all of them are Krohne's or Bob-Reuthers's.

We are in an investment period so i am about to purchase four new vortexmeters. Which brands do you advise?

I always use flowline gas meters (www.flowline.co.uk) in my applications. But remember you need to calibrate your meter for the pressure of your supply.

I have had very good luck with Yokogawa. Even though the name is Japanese, the meters are built in GA.

we use siemens

Foxboro

Anybody experienced with Endress+Hauser??

It has Profibus PA output , and price is not too high.

We use endress + hauser vortex technolgy to measure water steam with no problem. Hart communication.

I had quality and tech support issues with E+H stuff though that was a few years ago. I've used both Yokogawa and Foxboro vortex meters without any problems.

How do you get the flow info to the PLC or RTU?

I have more existing vortexmeters and i want to use HART to read them.But i could not manage to take the info to PLC or SCADA PC...

We use Foxboro and E&H. I prefer E&H simply because I cut my teeth on them as did a lot of folks. I would try this link for some help:
http://www.us.endress.com/

This is E&H home page here in the US. Search for help on HART comm. also they have a help line which I have used before. They have help centers worldwide. I have used both hart comm (which you can download the entire manual) and 4-20 mA for flow, pressure, DP, pressure what ever to PLC and DCS. You sould be good to go with E&H in the field.

It may be a device setup parameter problem biting you. Do you know for sure you device is functioning correctly. What exactly are you doing and with what instrument and I maybe able to walk you through it or somebody here ..... Lots of brain power on this forum ... Helped me many times

1) Any HArt device by definition has 4-20 mA signal, so you can always use a standard analog card.

2) Many brands of PLC have Hart communications I/O cards available. Check your supplier. These are often third party cards, so also search the web.
