Calibration is the comparison and adjustment of a reading from an instrument
in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
Many people think that we get cold and flu viruses more often in the winter due to the cold temperatures outside; however, this can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.

Air balancing is the process of testing and adjusting an HVAC system to deliver the correct amount of air to each room of a building. The most common tool used in air balancing is an air flow hood, which measures the volume of air coming out of a diffuser in order to find areas of the system where the flow is limited. The 2016 Dealer Design Award-winning SMART Air Hood® Balancing Instrument, Series SAH, was designed by your HVAC market leader to be the most accurate and easy to operate air flow hood on the market. But what exactly gives the Series SAH an advantage against comparable products? Continue reading “8 Reasons to Buy the SMART Air Hood® Balancing Instrument”
Introduction
Ball valves are designed to be used in a variety of applications and markets, but a V-port ball valve offers the added ability to be used as a control valve where necessary. The main differentiator is a contoured V-port in the ball, most commonly available with a 15°, 30°, 45°, 60°, or 90° angle, which produces an equal percentage flow characteristic for better control. V-ball valves are known to offer a variety of advantages in flow control applications, especially when compared to larger and more expensive control valves.

Valves are a vital part of any piping system, which means that they play a key role in the oil and gas industry. They can be used to control flow rates, to isolate and protect equipment, and guide and direct the refining process of crude oil. In this post, we will discuss five common valves that are used in the industry and what Dwyer Instruments, Inc. has to offer. Continue reading “Common Valves Used in the Oil & Gas Industry”
