Wireless Hydronic Differential Pressure Manometer, Series 490W

Dwyer’s Series 490W Wireless Hydronic Differential Pressure Manometer is the most accurate and easy-to-operate manometer on the market. Along with wireless transducers and a mobile device, a single operator using a 490W can monitor and balance a hydronic system in less time and with less manpower than would be possible using a traditional hydronic balancer. In addition, being wireless, the 490W has zero hoses or manifolds – meaning there are no annoying attachments that need to be carried, that can snag onto equipment, or that need to be drained between readings.    Continue reading “On the Job with Dwyer: Series 490W Wireless Hydronic Differential Pressure Manometer”

Mitigating Methane in Landfills

landfill degassing

landfill degassingIn the ongoing narrative of environmental conservation, few adversaries are as concerning as methane gas emissions from landfills. This potent greenhouse gas poses a substantial threat to both our climate and community health, demanding immediate attention and sustainable solutions. 

Landfills contain several different gases and volatile organic compounds (VOCs) caused by the breakdown of waste, with methane and carbon dioxide making up over 90% of them (health.ny.gov). Once waste breaks down and forms landfill gas and particulates, it can potentially spread to nearby buildings or structures through openings like cracks, windows, or ventilation systems and settle in areas of poor ventilation like basements or crawl spaces (health.ny.gov).   Continue reading “Mitigating Methane in Landfills”

Navigating Health and Comfort in Airports

In the expansive world of modern travel, airports serve as dynamic hubs connecting people across the globe. However, amid the seamless connectivity and operational efficiency, there exists a nuanced concern—the potential health implications associated with prolonged stays in these bustling environments. From temporary discomforts to potential long-term health risks, both passengers and airport employees may encounter various challenges unique to airport spaces.  

Although the COVID-19 pandemic brought concerns about the impact of the built environment on health out of the proverbial “back room,” experts have been mulling over solutions to these problems for decades. Airports are of particularly high concern as they act as something of a mini city. Jet fuel, exhaust, and other chemicals have a large environmental impact on the outdoor air quality, while carbon dioxide and volatile organic compounds (VOCs), like formaldehyde, can greatly impact the health and indoor air quality (IAQ) of airport occupants.  Continue reading “Navigating Health and Comfort in Airports”

Flow Measurement with Orifice Plates

Dwyer Instruments offers many types of flow measuring products including orifice plates, which are used as a flow sensing element with a differential pressure monitor.

Orifice Plates

Orifice plates are a primary flow element, detecting the flow of a fluid passing through the plate by sensing the pressure drop across the plate. When a fluid flows through a restriction in a pipe, it creates a pressure difference between upstream and downstream of the restriction. This pressure difference is proportional to flow rate according to Bernoulli’s principal, similar to a Pitot tube.  Orifice plates are commonly used as they are simple to use, low cost, work with gases or liquids, and require low maintenance.  Adversely, they do have large pressure losses with about 50% of the pressure drop not recoverable.  Continue reading “Flow Measurement with Orifice Plates”
