Dwyer Instruments, Inc. offers many types of flow measuring products including orifice plates, which are used as a flow sensing element with a differential pressure monitor.
Orifice plates are a primary flow element, detecting the flow of a fluid passing through the plate by sensing the pressure drop across the plate. When a fluid flows through a restriction in a pipe, it creates a pressure difference between upstream and downstream of the restriction. This pressure difference is proportional to flow rate according to Bernoulli’s principal, similar to a Pitot tube. Orifice plates are commonly used as they are simple to use, low cost, work with gases or liquids, and require low maintenance. Adversely, they do have large pressure losses with about 50% of the pressure drop not recoverable. Continue reading “Flow Measurement with Orifice Plates”
The Mercoid® Division of Dwyer Instruments, Inc. offers four series of submersible level transmitters with different features suitable for different applications: the FBLT, PBLT, MBLT, and SBLT.
Submersible Level Transmitters are pressure transmitters manufactured to read hydro-static pressure from inside the fluid. These transmitters are submersed into the fluid that they are measuring and will give an output proportional of the fluid level above the sensor location.

Bimetal Thermometers measure temperature based on the differences in thermal expansion properties of metals. Pieces of metals with different thermal expansion coefficients are attached to each other in an assembly.
The Dwyer Instruments, Inc. website was launched 21 years ago and was one of the first instrumentation e-commerce websites of its kind. Over the years as new products and features were added to the site, navigation became more complex for new users. Dwyer continually strives to improve the user experience by making platform updates and reducing the number of clicks it takes to find and order a desired product. To that end, users will begin to see navigation updates on the W.E. Anderson® by Dwyer Valve Automation website (www.weavalves.com) in May. To round out 2017, these changes will incrementally be updated across the entire Dwyer platform. Continue reading “Find What You Want In Less Clicks”
Understanding the necessary requirements for your product’s enclosure ratings is important, particularly when looking to gain the optimum life from your product while avoiding any safety concerns. Included below is a straight forward easy to understand overview of enclosure ratings, including NEMA types, IP ratings, and the difference between the two. We will be looking at these two common standards for industrial enclosures, what they equate to, some alternatives, and how to best choose the right one for your application.
