What is a Hydronic System and What is Needed to Balance it?

A hydronic system is a system designed to circulate chilled or hot water with the connections between piping and terminal units (heating and/or cooling devices). Most hydronic systems are closed and are usually made in a series loop. In addition to pipes and terminals, valves are placed in this series as a port to balance the differential pressure in the system. The balance of this type of system is often referred to as hydronic or hydraulic balancing. Continue reading “What is a Hydronic System and What is Needed to Balance it?”

What is Pressure and How is it Referenced?

Many Dwyer Instruments, Inc. products sense and measure pressure. This includes: gages, manometers, transmitters and switches.

Pressure is the amount of force acting on a specific area and is equal to the force divided by the area.

There are many types of pressure that are used and measured, including: atmospheric, absolute, gage, vacuum, differential and hydrostatic. Continue reading “What is Pressure and How is it Referenced?”
