How do I correct my variable area flow meter for a gas with a different operating density? [FAQs]

September 27th, 2013 No comments

Now for the “gas” version of the equation…

Problem:
You want to get a quick flow check on a different gas because the process gas is changing or you might be experimenting with the process, but you don’t have a VA (variable area) flow meter that is calibrated for the different gas.

Solution:
Enter the necessary information into the equation below and you’ll get the flow rate for the different gas.

Variable Area Flow Meter Gas Correction Equation

Things to Keep in Mind:

  • The meter has to be a size 8 (1/2” nominal size) or larger and of course the flow meter has to be capable of measuring the flow of the different gas.
  • Absolute Scale Unit Conversions:
    • psia = psia + 14.7
    • °R = °F + 460
  • If your experiment is successful, I recommend you get a meter so you don’t have to calculate the flow rate every time you use the different gas.

Correction Equation for Liquid Flow

 

Things to Keep in Mind:

  • The meter has to be a size 8 (1/2” nominal size) or larger and of course the flow meter has to be capable of measuring the flow of the different fluid.
  • If the new specific gravity is drastically different, the meter may not be capable of registering a flow rate for the new fluid.
  • If your experiment is successful, I recommend you get a meter so you don’t have to calculate the flow rate every time you use the different fluid.

What I learned at SEMICON West 2013

July 26th, 2013 No comments

CelerityLogoIt never, ever fails – each time I get out of the office and into the marketplace, I come away with insights and ideas.

At SEMICON West 2013, there was so much to absorb about the industry, suppliers, competitors and customers. But when I hone in on my key insights and what they mean to Brooks Instrument and the people we have the honor of serving, this was numero uno:

What may be old news to us could be “new” news to the marketplace, for a very long time…

Here’s what I mean – back in 2009, Celerity, Inc. joined the Brooks Instrument family. Celerity brought its rich history of growth and innovation in the semiconductor market to Brooks, including well-known mass flow controller brands like:UnitMFC
• Celerity
• Unit
• Millipore
• Mykrolis
• Tylan General

Although we communicated this to the marketplace in a variety of ways, not a single visitor to our booth was aware. That means all of you out there who currently own one of these devices are missing out on getting the best factory certified service for your device as well as the opportunity to upgrade to the latest technology, like our GF100 Series thermal mass flow controllers. This technology platform has been designed to precisely measure, monitor, and control ultra high purity process gas chemistry in semiconductor device manufacturing processes.Mykrolis

We are here for you! If you’d like to know more, email or call us at 1-888-554-3569.

Brooks Featured in Solid State Technology Magazine

June 14th, 2013 No comments

Our own Shaun Pewsey was quoted extensively in the May issue of Solid State Technology in an article on page 10 titled, “New MFCs Mean Higher Yield.” The article discusses the latest advances in diagnostics for semiconductor production.

Brooks’ new GF135 is featured because it is the first MFC that can test process gas flow without stopping production. Instead of having to take the gas panel offline to run diagnostics, the GF135 uses real-time error detection by momentarily closing the valve. This promises semiconductor manufacturers increased accuracy and increased yield. “In short, the new technology identifies and corrects issues before they happen, preventing wasted time and wasted wafers.”

We hope you enjoy the article. Give it a read here.

XacTorr CMX guages revealed at SVC TechCon 2013!

April 23rd, 2013 No comments

Process production can be tricky. In the past, we’ve covered ways to ease the pain of process manufacturing, and today we’re excited to introduce a game-changing development to the industry. Our vacuum measurement expert Ken Tinsley will be presenting a poster session at SVC TechCon 2013 in Providence, R.I., where the XacTorr CMX line of vacuum gauges will take center stage.

The XacTorr CMX line will break new ground, as they’re the first digital capacitance manometers to enter the market. The secret is the Mark-IV sensor built into the gauges. The surface chamber has areas allocated for vapors and particles to group without affecting the sensor. This feature not only extends the sensor life but also increases productivity by reducing the need to re-zero.

Tinsley’s presentation, “Advantages of Digital Calibration in Second Decade of Capacitance Diaphragm Gauges”, will take place today at the Rhode Island Convention Center from 4:00 to 6:00 p.m. As a proud sponsor of the show, we’re offering free admission to anyone interested in learning more about our vacuum technologies. If you’re in the area and would like free admission to the show, simply email your name, company and email address to BrooksAM@BrooksInstrument.com.

We hope to see you at the show!

Our MT3809 VA Flow Meter is New and Improved!

April 19th, 2013 No comments

Big news here at Brooks. We’ve got another product launch underway. This one involves a redesign of our MT3809 VA flow meter. That great instrument just got even better.

The new MT3809 works accurately across a staggeringly wide range of operating temperatures — from -50°C to 420°C (-58°F to 780°F) — and at pressures to 1380 bar (20K psi). Even in the most demanding applications measuring gases, liquids, and steam, the MT3809 delivers 2% full-scale/1.6 VDI accuracy. We’ve given the new MT3809 an explosion-proof housing that meets the world’s most stringent hazardous-area classifications, and we’re offering a flameproof option for IIC/Class 1 Division 1 locations.

All in all, you’ve got unprecedented flexibility to use a single flow meter regardless of application, process configuration or flow rate.

Of course we always like to design for value as well as quality and durability, so you can expect the new MT3809 to save you plenty of time and money over the course of its long service life. For starters, installation is fast and easy. That includes retrofitting. Maintenance is simple, too. Weldneck flanges provide long-term durability in all configurations. You don’t need back pressure for gas applications, and we’ve met ASME sealing specifications with a standard gasket, saving you the cost of custom gaskets.

As always, we’d be happy to tell you more about it. Email me, or call us at 1-888-554-3569.

Brooks Team Members Participate in the SolarRun

April 18th, 2013 No comments

On a sunny Saturday in Holland, team members from Brooks Instrument hit the ground running for the SolarRun, a 5k/10k fun run that benefitted the Solar Without Borders organization.

Brooks Instrument was eager to participate in the event as it helps to increase funding and awareness for Solar Without Borders, a charity that works with a variety of industries to provide photovoltaic panels to hospitals, schools, and orphanages in countries with limited electric infrastructure. Solar Without Borders originally started in West Africa and now operates in numerous countries around the globe including Guatemala, Kenya, and Mongolia.

Poor conditions often exist in hospitals with no or little electricity. Solar panels on these buildings will help to keep medications refrigerated and thus fresh for longer periods of time. Electric lighting also reduces dependence on oil lamps commonly used in maternity wards. The lanterns are known to emit harmful chemicals into the air.

Solar panels can impact literacy rates in impoverished countries. In Burkina Faso, where the literacy rate is only 28.7%, Solar Without Borders hopes to increase literacy by providing electric lighting for children to complete their homework.

The SolarRun is organized by Tempress Systems, a Dutch customer of Brooks Instrument active in the solar industry. Tempress believes strongly that a healthy world is important and they encourage their employees to keep physically fit and to stay energetic. Brooks Instrument shares these values and was excited to both sponsor and participate in the event. Read more…
