Submetering is the installation of metering devices with the ability to measure energy usage after the primary utility meter. Submetering offers the ability to monitor energy usage for individual tenants, departments, pieces of equipment or other loads individually to account for their actual energy usage. With submetering, a clear and accurate picture of how and when energy is being consumed inside a facility is created.

The Internet of Things (IoT) is changing the way people run their homes. More and more devices are becoming available to consumers that allow them to automate their thermostats and regulate their power consumption, often-times controlling these systems from the phone in their pocket. Products like the Nest thermostat and the Sense home energy monitor provide homeowners convenient tools that also help save utility costs.
In commercial and industrial buildings, there are similar (albeit far more robust) systems and protocols used for the same purposes called building automation. Building automation is the automatic and centralized control of a building’s heating, ventilation, air conditioning, security, electrical, and other systems through a Building Automation System (BAS).

Absolute Pressure Defined
Absolute pressure is measured relative to a full vacuum. Alternatively, pressure that is measured against atmospheric pressure (also known as barometric pressure) is called gauge pressure. A full vacuum has an absolute pressure reading of 0 PSIA and average barometric pressure at sea level is ~14.7 PSIA.

Ensuring the accuracy of transducers used in the measurement of room pressure in critical environments is extremely important in order to maintain patient safety. Because the differences in measured pressure are so small (only fractions of an inch of water column) calibrating these devices can be very tedious and usually difficult to perform without the right tools and processes.
In general, there are two industry standard methods of low pressure calibration: hand pump calibration and automated calibration.

When first selecting a pressure transducer for a new project or piece of equipment, designers typically focus on key design parameters such as pressure range, electrical output, media compatibility and environmental conditions. However, those parameters are not the only ones to consider when making a smart choice for an application. There are three design considerations that are often overlooked when selecting a pressure transducer: transfer medium (oil filled vs. non-oil filled), construction, and type of sensing technology.

The Joint Commission (TJC) is a non-profit organization that evaluates and accredits healthcare organizations in the United States, ensuring that hospitals and other medical facilities are providing safe and high-quality care to their patients. Inspections occur every three years and take between 2 to 3 days. In most jurisdictions, Medicare and Medicaid funding is contingent on accreditation by TJC.
One of the most important standards scored in a Joint Commission evaluation is room pressurization (EC.02.05.01). According to ASHRAE Standard 170 (used specifically by TJC as its standard), over 60 different areas of concern within a facility need to be either positively or negatively pressured. Pressurization in these spaces is tested simply by holding a tissue at the bottom of a door and determining whether the tissue is blown back away or sucked towards the gap.

In hospitals, pharmaceutical compounding centers, and other sensitive healthcare environments, one of the biggest threats to patient health is the spread of pathogens. Exposure to viruses, bacteria, pollen, and fungi all pose hazards to patients and care providers and can compromise critical spaces like operating rooms and other procedure areas.

Did you know that companies spend hundreds of millions of dollars on research and development for off-highway vehicle engines? A portion of the R&D goes into developing specialized engine test stands to ensure that the engines are functioning properly.Engine test stands are complex, engineered systems designed to measure, control and record parameters during the different engine manufacturing stages.

Although hydrogen is in its infancy as a fuel source, its future is incredibly bright. The technology behind hydrogen fuel cells is improving by the day and its viability as a replacement to the internal combustion engine seems likely. Hydrogen is already being used in specialty vehicles such as forklifts and buses, and it’s only a matter of time before infrastructure is in place to serve the consumer automotive market. Why do hydrogen fuel cells have such great appeal? Because their only byproducts are heat and water vapor, making hydrogen fuel cells a truly zero-emission locomotive technology.
