Protect Your Capital Assets: Water Leak Detection

When it comes to Building Automation and Management Systems, companies invest in the latest and greatest technologies to optimize their process efficiency. Many hours and thousands of dollars are spent to ensure minimum power consumption and reduced heating and cooling costs. However, the conversation of protecting these capital investments are a less frequent topic of discussion. Additionally, protecting the structural integrity of the facilities can be an afterthought. Any sign of moisture and leakage can be the beginning of a serious component failure. For this type of monitoring, Dwyer Instruments, Inc. offers the Model WD Water Leak Detector for protection against potential water or liquid damage.

Open Channel Flow Monitoring

Open channel flow monitoring is a method of measuring water flow rates in irrigation channels, streams, and storm water systems. It’s also used in wastewater processing for monitoring the effluent discharge. In most applications for open channel flow, weirs and flumes are used. For those of us not familiar, weirs and flumes concentrate the flow into a known cross sectional area, relating an accurate level reading to an accurate flow rate. The height of the water in the channel, going over the weir or flume, is directly proportional to the flow rate. Continue reading “Open Channel Flow Monitoring”

Outside Air Humidity

This week is Air Quality Awareness Week, which is promoted by AirNow to discuss the importance of healthy air for everyone. One vital part of air quality involves monitoring humidity and temperature, so using an accurate outside humidity and temperature sensor can have a significant impact.

Most air handling units (AHUs) use what is called an economizer cycle. This is when outside air is mixed with the return air to cool the building dependent upon the outside temperature. However, if the air is too dry and requires humidification to accomplish this process, your cost savings may have been eliminated due to the AHUs humidity control, which provides excessive steam for this humidification procedure to take place. Consequentially, sometimes based on weather conditions, your economizer may just be costing you money instead of saving it. Continue reading “Outside Air Humidity”

Manufacturing an Economic Dust Filtration System

Solenoid Valve Enclosure with Timer, Series SVT

Many customers have come to the Dwyer team asking: “What can Dwyer do to help with lean manufacturing?” In this article, we will discuss the Dwyer® Series SVT solenoid valve and timer enclosure and its cost savings advantages in a dust filtration system.

The Series SVT combines two integral components in a dust filtration system into one package: solenoid valves and a timer controller. In a dust filtration system, solenoid valves are used to send air through a pulse valve, such as our Series RDCS.  Pulse valves release a quick spurt of air into a dirty dust cartridge filter, which, in turn, releases the dust from the filter. The timer portion of the dust filtration system is the brains of the operation controlling when the solenoids fire, the amount of time the solenoids are open, and when the next solenoid in the sequence fires.

Parking Garage Ventilation Control

Carbon Monoxide/Nitrogen Dioxide Gas Transmitter, Series GSTA

The Series GSTA carbon monoxide/nitrogen dioxide gas transmitters offer a robust, low cost alternative to standalone garage ventilation control packages.

As cities around the world continue to grow, the need for parking becomes an integral part of new commercial and municipal building plans. Many building designers are finding ways to offer adequate parking in a limited amount of real estate. Two emerging trends to do so are enclosed parking garages and mixed-use parking garages. Both of these designs seek to offer users a comfortable way to park their vehicles, all while being near their final destination. This means that the parking facility and the commercial or residential buildings are not separated, but are integrated together into one building structure. Due to this integration, two major concerns arise. How do we ventilate the harmful exhaust from the vehicles while being so close to the populated areas of the building, which require clean air and how do we accomplish this in the most energy efficient way possible? The Dwyer® Series GSTA carbon monoxide/nitrogen dioxide gas transmitters offer the sensory inputs necessary for any building automation system to answer this very quandary in an efficient and low cost manner.
