Air flow switches are used in applications that require low to high velocity, providing an economical way to detect change or loss of air flow velocity. Trip points are field adjustable, so you are always able to adapt quickly to changes in system conditions. How Do I Get One? Includes Nema 4x enclosure rated for all classes, divisions and groups. They are rugged and robust to withstand outdoor installations and carry global agency approvals for application in explosive, hazardous environments.

Flow Switch Uses A liquid flow switch is applicable in , hot water heating, air conditioning, liquid transfer systems, fire sprinkler systems, and industrial laser cooling systems. When the flow of media reaches the existing set point, the switch prompts the pump or other mechanism to turn on or off. Cookies are required for many of our site's features to work properly. A flow switch operates by conveying a trip motion relay, reed switch, paddle to another machine within the system, usually a pump. In particular, we want to make sure that we are respectful of your data protection preferences, and that you understand your data privacy rights.
It's spring loaded with mechanical design mounts in any orientation. Liquid flow switches can be used for air conditioning, hot water space heating systems, pump systems, water cooled equipment, blending or additive systems, liquid transfer systems, fire sprinkler systems, water treatment systems, swimming pool chlorination and industrial laser coolant systems. Construction materials include brass, 316L S. They can be used in vertical or horizontal lines. Vertical pipe installations must be specified on the order and require a special spring loaded vane. Please enable cookies in your browser preferences to continue. Trip response times generally range from 2 to 25 seconds and can optionally be extended with a time delay.
This type of cookie should be enabled at all times so that we can save your preferences for all other cookie settings. Clear flow tube allows for view of process and scale, and spring loaded mechanical design can mount in any orientation. The thermal flow switch is available in liquid or gas configurations, including low-flow detection. Boiler Flow Switch Safety Device The boiler flow switch is critical to the safety of your boiler. The flow switch can easily be tested without having to disconnect the electrical leads or dismantling the switch. Some of the more common types of flow switches seen in current production include differential pressure switches reading the difference in pressure between two points based on friction loss during flow , paddle switches a simple spring return switch that is made closed when there is flow present and off open when there is no flow and magnetic switches.
Air flow switches are used to clean room filter systems, exhaust ventilation, and air treatment systems. Whether you are buying for the first time or know exactly what you need, our trained application engineers are ready to guide you through the buying process. Water flow switches are implemented in water sprinkler systems. If this does not work, you may need to upgrade your browser. Max pressure is 1Mpa; Specification: Application chillers,water heater and other circulating water system. Every flow switch has a set point, which is a maximum or minimum flow rate. This sequence of events results in the increase or decrease of the flow rate, depending on the requirements of the application.
This change or loss may be caused by a closed damper or fan inlet, loose fan wheel, slipped or broken fan belt, dirty or clogged filter, or an overload on a fan motor switch. Calculating the flow rate must be done as it assists in setting to a pre-determined close function. When the flow of water stops, the magnet moves away from the reed switch, which opens it and breaks the electrical circuit to the burner systems. Low flow water switch products are most popular in Domestic Market, North America, and Mid East. From critical monitoring of extremely low flow process additives to loss of flow protection in large water or air lines, we can handle most flow switch applications.
At high flow rates, flow removes more heat, resulting in a lower differential. Overview of Flow Switches Flow switches play an important role in regulating the flow rate of fluids through a system. Related Question What precautions should be taken when installing a V4 switch in an extremely high flow application? Standard wetted parts are Grade 316 stainless steel, with other materials optionally available. The set point is typically user-adjustable. If your boiler flow switch has problems, it's imperative to consult with a boiler professional for a solution.
