One of the most harmful and common substances to greatly affect people’s health is lead. Lead is a carcinogen which can be found in some percentage of most everyday materials. Varying forms of lead exposure can come from paint in older homes, dust, soil, and drinking water. To avoid health risk, individuals should take precautions to reduce or eliminate the possibilities of exposure. Ensuring and minimizing livestock and poultry exposure to lead contaminants helps to reduce human exposure via the food supply. Continue reading “Reducing Lead in Animal Watering Systems”

Rotary Paddle Level Switches Re-Invented
The Proximity Controls Division of Dwyer Instruments, Inc. specializes in both bulk level monitoring and valve position indication. Rarely do these two sides of the business intersect. That is until the engineers at Proximity Controls came across a challenge to improve an industry standard level sensing technology. Continue reading “Rotary Paddle Level Switches Re-Invented”
Market Shifts & the Need for Backward Compatible Products
Technology markets shift. The shift can be incremental, radical, or sometimes disruptive.
Take, for instance, gages used in process automation markets. Gages command about $3.5 billion in global instrument sales, the major portion, over $11 billion now held by transmitters.
The technological shift from a visual indication gage to the first transmitter has been incremental. It has taken over 50 years for transmitters to go from concept to commanding 70% market share. Continue reading “Market Shifts & the Need for Backward Compatible Products”
Flow Measurement with Orifice Plates
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”
