I am currently working on my senior project at California State Polytechnic University of Pomona. The project is to rebuild a Cummins 24 valve 5.9L diesel engine and couple it with an older dynamometer we have. The dynamometer uses some archaic rotameters for the flow rates of diesel and a drum with a specific opening that you have to then use a chart to find what the mass flow rate of air is. I am looking for a meter for each application that has a remote display so it can be mounted inside the lab room.

Thank You,

A thermal dispersion (hot wire anemometer) flow meter for the air flow would have the turn down necessary for low speed through high speed. Sierra Instruments is out your way, Kurz does that, too.

For fuel metering, a turbine meter is the classic choice for accuracy.

Google will find you lots of others, too.

For Air Kurz Thermal Mass would be an ideal choice. Use Hoffer Turbine Meter for liquid provided it is to be measured in volume else for mass use Micromotion Coriolis.

You are not wrong in your recommendations, Rohit, but since this is a neutral, non-commercial forum, I'd like to expand it a little bit. That way, other people get to play too. Since Robert is a student, he may need to ask vendors to comp him some equipment. The more vendors we can give him, the more likelihood he can find one willing to help with his project.

There are at least 25 manufacturers of thermal mass flow meters, including FCI, Fox Thermal, Sierra Instruments, Bronkhorst, Aalborg, Brooks div. of Emerson (at least for now... next month they'll be a division of somebody else) and many more who you didn't list. And they are all as good as Kurz.

Hoffer makes a good, workmanlike turbine meter, but so do over 100 other manufacturers including Racine Federated, EMCO, Trimec, McMillan, AW, Sponsler div. of IDEX, and lots more... this isn't alphabetical because I'm doing it cold out of my head.

And in the mass flow area, Micromotion isn't the only player there, either... and isn't even always the best choice. For a complete evaluation of all types of coriolis meter, see David Spitzer's and my "Consumer Guide to Coriolis Mass Flow Meters" available from ISA press and Amazon.com or direct from httP://www.spitzerandboyes.com. Endress+Hauser, Krohne, FCI, Yokogawa, and others make excellent coriolis meters that compete quite well with the Micromotion meters.

Good luck.

 

Yes, there are many players who do manufacture quality products. If you know them all you can better evaluate the best one or the one that can help you solve your flow metering application. As every coin has two faces so do every manufacturer hence your analysis & evaluation to suit your application is key to a great product performance.

I referred the one that I have used, sold & experienced it to be a reliable products.

 

That's one of the reasons David Spitzer and I started to publish the "Consumer Guide to..." series, many years ago. We found it impossible for an average engineer at a plant to do a detailed enough evaluation, and there was no such thing as a completely unbiased comparison tool available. So, David and I made one.

We now have published guides to magmeters, vortex and fluidic meters, coriolis meters, ultrasonic and correlation flowmeters, and differential pressure flowmeters, as well as guides to several types of level measurement devices. The heart of each of these is an exhaustive listing of vendors, a list of products by feature, and a list of performance (accuracy) by model number.

We're continuing to publish guides as fast as we can publish them, and people keep asking us for more and different ones, like the Consumers Guide to pH, ORP and Conductivity by David Mills, that we published last year, and the Fieldbus guide that Dick Caro wrote, and more.

We're working on a DCS guide, too.

The fact is, the average automation professional needs this kind of help to be able to do the evaluation.

 

I treat you, Mr. David Spitzer & Mr. Jesse Yoder as Flow Measurement Guru...if Corporate Management can have Management Gurus you guys have done excellent work in flow measurement & automation to be very well called as "Guru" in Control & Instrumentation or Flow Guru. Why don't you write a article on the same.....Gurus in Automation & Controls.
