How the Dwyer Series IEF and IEFB Overcome Typical Sources of Error

There are a wide variety of technologies that can be used for fluid flow measurement, such as differential pressure, paddlewheel, electromagnetic, and ultrasonic. Furthermore, each technology has multiple installation configurations. It is important to understand the nuances of different technologies and installations in order to pick the right flowmeter for your application. 

When purchasing a flowmeter for an HVAC application, such as boiler feed water monitoring or chilled/condenser water monitoring, we found that our customers value the ability to hot-tap (or pressure tap) a pipe to install an insertion flowmeter. This is done by installing an isolation valve in a pipe, allowing an insertion flowmeter to be placed into and removed from a live system without having to drain it. Draining a system is time consuming, costly, and generally not a good option for HVAC systems in buildings because it requires the entire system to be shut down. Permanently installing a hot-tap valve followed by an insertion flowmeter (with hot-tap capability) is an ideal alternative to a costly inline meter. 

When considering an insertion flowmeter for an HVAC application, there are four key sources of error to be aware of:  Continue reading “How the Dwyer Series IEF and IEFB Overcome Typical Sources of Error”

Dirty Jobs | Measuring Livestock Manure Level

Imagine that you’re driving down a country road, and you roll down your window to feel the breeze from the wind. You happen to look to your side as you pass a large barn housing dairy cows. Most of us have seen these farms, but many don’t think about what happens to the manure of the animals or how it is utilized in our everyday lives. Manure slurries and lagoons are a vital function of large scale farms for swine, dairy, and poultry.  Continue reading “Dirty Jobs | Measuring Livestock Manure Level”

Decrypting Thermal Energy Meter Accuracy

“Simplicity is the ultimate sophistication” – Leonardo da Vinci

These days, energy conservation is on everyone’s mind. From cost savings to environmental concerns, there are many well-known benefits to conserving energy. But understanding exactly how to do so can be confusing. In order to conserve energy, you must know precisely how much energy you are using.

There are many different methods and tools that can be used to measure your energy consumption, depending on your application. In this post, we will focus on thermal energy measurement and management in hydronic systems. In keeping true to Da Vinci’s quote, we will keep our explanation as simple and straightforward as possible.

Well Water Monitoring for Irrigation Systems

Irrigation is fundamental to the production of food all over the world. Most of us have seen the large center pivot systems used on many farms today, and there are a number of other technologies that are designed to deliver water to crops to allow them to flourish. Less prominent, however, are the systems that collect and deliver water to these irrigation systems to allow for crop growth. Continue reading “Well Water Monitoring for Irrigation Systems”
