I am offering "Square Root Scales" for sale.
These scales are marked in "Percent of Flow" and will bolt directly to a Dwyer 246 inclined manometer.
They should be easy to adapt to any homebuilt inclined manometer. They are 20.5" long with a mirror finish for optimum viewing of the meniscus.
I am offering them at $35.00 each for our Flowbench & Dyno Forum members. That includes shipping in the lower 48 United States. Out of country sales will be handled on a case by case basis, if it comes up.
Contact me via "PM" on the forum, or e-mail me at:
