How Ultrasonic Flowmeters Work

animation of flow moving through ultrasonic flowmeterUltrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. When the fluid moves faster, the frequency shift increases linearly. The transmitter processes signals from the transmitted wave and its reflections to determine the flow rate. Continue reading “How Ultrasonic Flowmeters Work”

Storing Food Safely: How Dwyer Can Help Meet HACCP Refrigeration Control Standards

Unless it’s recently stopped running (or run away), you probably haven’t paid much attention to your refrigerator lately. Despite enjoying status among the largest and most frequently used appliances in your home, the refrigerator is a bit of an unsung hero, quietly humming away in your kitchen, keeping lettuce crisp and ice cream velvety smooth. But refrigeration is about so much more than fresh greens and tasty frozen treats; the humble fridge is also the first line of defense against foodborne illness.

Historical trivia: The first practical, ice-cooled refrigerator rail car was invented in Chicago for Swift & Co. in 1878, revolutionizing the meat packing industry and changing the way we eat forever. (Wikipedia – Gustavus Franklin Swift)

According to the CDC, there are 31 pathogens known to cause foodborne illness. In the United States, these pathogens, including norovirus, salmonella, and even Staphylococcus aureus (Staph), are responsible for an estimated 9.4 million cases annually. Many of these cases go beyond typical food poisoning symptoms, resulting in 56,000 hospitalizations and 1,300 deaths.

The Operation of Gages and Switches in Hazardous Environments

In many industrial processes, the materials and the end product or by-products of the process, such as dust or vapors, can create conditions for a hazardous environment. Processes that have potential for hazardous environments include: water treatment, oil drilling, gas and chemical processing, power generation, pharmaceutical, and food manufacturing. The measurement and control of these processes are essential in maintaining optimal conditions of the manufacturing system and preventing catastrophic events.  Continue reading “The Operation of Gages and Switches in Hazardous Environments”
