PWLs and TATKs

It’s been a while since we last posted and a quick update is long overdue. In the past few years, we’ve added the Tightwire Alignment Tool Kits (TATKs) to our portfolio in addition to the Precision Water Levels (PWLs). Both are high quality tools that are made in the U.S.A. We continue to assemble them at Equipment Development Services in Schenectady, NY and continue to operate out of our office in Pittsburgh, PA.

We are open and safe!

In light of the ongoing COVID-19 coronavirus pandemic, please note that our facilities are fully operational. We have excellent disease containment procedures in place and do not have any reported infections or symptoms.

The PWL-2 Has Arrived!

The Precision Water Level (PWL) version 2 is now available. It is more accurate than our PWL-1, less impacted by temperature, and additional water cups to expand the system are priced much lower. PWL-2s utilize many of the same components and processes as PWL-1s allowing owners of PWL-1s to upgrade with minimal cost. Please contact us or see our PWL page for more details.

New Standard PWL Kits are Here!

Our new Standard PWL Kits use precision made urethane water cups, which are durable, highly accurate, and inexpensive. An entire 4-cup kit is under $2,000, providing most users with a full return on investment in a single use. Visit our PWL page to learn more.

PWL’s Patent Protection

The PWL device, system, and method used to measure level and flatness are protected by U.S. Patents 9,587,940 and 9,273,988 “Precision Hydrostatic Level and Flatness Measuring Device, System and Method”. The PWL-2 is protected by these patents and elements specific to the PWL-2 are patent-pending. The use of any tool to measure level or flatness according to the methods recited in our claims that we (EDS Precision Systems or Equipment Development Services) do not manufacture infringes on our patent, regardless of the reason the tool was created. It’s also important to know that we haven’t authorized anyone else to make, sell, advertise, or import the tools recited in our claims. Owners of our PWLs are granted a license to use our method only for a PWL device we manufacture. For example, if you purchase an eight-cup PWL kit, with a second micrometer assembly and four additional cups that we made, you are receiving a license to use our method to conduct one level or flatness measurement at a time per micrometer assembly at one measurement location per cup, so in this case two measurements at a time at twelve measurement locations. In other words, we’re selling a tool that should not be copied. Never purchase any duplicates or knock-offs and please let us know if you come across any. While we will rigorously enforce our patent, we hope to avoid this by offering great value through low prices, excellent customer service, and a high quality tool that often pays for itself within one or two uses.

Featured GE Supplier

We’re happy to announce that we’re the only GE supplier in Virginia featured on the Faces of GE website. Our Precision Water Level (PWL) reduces the time needed to take measurements on large leveling and flatness projects by 80% or more. GE saves nearly two days of time with every steam turbine assembly they do (which doesn’t count the time savings when leveling the turbine foundation), resulting in a return on investment (ROI) for the PWL of less than 6 months. To put that in perspective, at the 2016 International Manufacturing Technology Show in Chicago, the consensus was that an ROI of 2 years is normal for a new tool. Update: Although we’re still listed as a Virginia business, we’ve moved to Pennsylvania and the link to our interview on the Faces of GE website does not work.

Made in the U.S.A.

We very much appreciate our U.S. customers asking if our Precision Water Levels are made in the United States, especially since we are a veteran-owned business. The answer is, yes, all of our PWL parts are made in the U.S.A and all assembly, calibration, customer support, and other office functions are done in the U.S.A.
