Trade Show Update


Trade Shows have been cancelled for 2020 and we are disappointed as you are. BUT, in anticipation of this reality, we have been working hard to create a new-to-the-world virtual booth for our devoted Customers. You will hear more about this in the next weeks, but look for:

  1. Live streaming content with industry experts
  2. Demonstrations with service techs of our equipment
  3. Live chat with Sales and Service staff to discuss industry needs and innovations
  4. Watch as some of the most popular SuperFlow and DYNOMite products are being built
  5. the coolest opportunity the industry has ever experienced – YOUR chance to interact with our Innovation team to finalize versions of software and controls

SuperFlow views this year as an opportunity to engage with you in ways we haven't been able to in the past. Please visit our show page to register for additional information as it becomes available.

Test Pressures and Comparing Flow Numbers

February 15, 2020

The necessity of flow-number comparison is something that anyone involved in flow testing must endure. Even if the number comparison is done on the same components and flowbench, it is important to know how to compare the numbers so the time and effort is worthwhile. The comparison process is necessary to evaluate published numbers vs. your own developed flow numbers. The first thing you learn in flow testing is that you must ask (or qualify) at what test pressure the flow numbers were recorded.

Even though the SuperFlow instruction manuals provide a chart for comparing flow numbers from one test pressure vs. another test pressure, not everyone has one, so the following information is supplied for easy use.

The chart in the SuperFlow instruction manuals for flowbench operation is based on the square root of the pressure ratio method. If you have flow numbers at a known test pressure and want to compare those numbers at a different test pressure, it is easy to do.

As an example, if you have flow numbers at 10″H2O test pressure and would like to know what the flow should be at 25″H2O test pressure, . So you would multiply the flow numbers taken at 10”H2O test pressure by 1.58 to see what the flow should be at 25″H2O.
