We talk a lot on this blog about the importance of indoor air quality in schools to boost students’ well-being. Also important to the school building is ensuring that the building is energy efficient – the dollars saved by reducing energy consumption can be used to further improve school facilities and enhance students’ learning environments.

Concrete is used all around us as foundation for buildings and exterior surfaces, parking lots, sidewalks, countertops, and more. Although walking or riding a car on concrete is a daily occurrence, it’s easy to overlook the basic elements that go into this essential of modern living.
Concrete is made of a few basic components:
Of these components, the ratio of water to cement is particularly important. Continue reading “The Importance of Water in Concrete Mixing”
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”
