VACUUBRAND's dry, chemical resistant pumps provide an ideal solution for use in process development, scale-up work, and kilo labs. With no sealing fluid to replace, our dry pumps provide a low maintenance, low operating cost alternative to oil-sealed rotary vane…
A Midwest chemical plant serving the automotive and OEM market needed to replace an aging carbon steel horizontal cylinder bulk storage tank with a new stainless steel vertical cylinder tank. The customer needed an overfill protection solution for the tank…
Endress+Hauser non-contact radar measures level in corrosive chemical tanks A U.S. water treatment plant operating at 85 MGD capacity was in need of accurate and reliable level measurement for chemical tanks with product density variations due to temperature changes, without…
Pirani gauges are a group of indirect measuring pressure gauges which measure the thermal conductivity of the gas sample. Pirani gauges are typically used in the fine vacuum range (1 torr - 10-3 torr), as this is the range where…
Determination of pH is a critical and ubiquitous operation whenever water is used in the chemical process industries (CPI). This one-page reference provides a review of pH chemistry and information on pH measurement equipment in CPI applications. Chemistry of pH…
In one of our prior posts, we talked about the key differences between direct and indirect vacuum gauges. One of the most common direct gauge technologies is the capacitive gauge. This post will review how these gauges are constructed and…
Finding a vacuum gauge for monitoring chemical processes can be a challenge. There are few gauges that simultaneously cover the appropriate vacuum range with sufficient accuracy and have the ability to cope with regular exposure to aggressive chemicals. VACUUBRAND's VACUU·VIEW™…
Because vacuum technology spans 15 orders of magnitude (103 mbar - 10-12 mbar, or 760 torr - 10-12 torr), there is no single vacuum gauge that can cover the full range. Consequently, a number of different gauge technologies have…
In our last post, we talked about our pump selection guide as one tool that we've made available to identify the right vacuum pump for your needs. This is a great tool to use to quickly narrow down your options, especially…
With a focus on flowmeters, this article shows how advances in measurement technologies help safety system designers reduce risk and cost in their safety instrumented systems (SIS) design and lifecycle management Successful implementation and management of a safety instrumented system…
