The McDonnell Miller FS7-4E Flow Switch with Explosion-Proof Design is a high-performance, reliable, and safety-focused instrument designed for industrial fluid applications. This flow switch is specifically engineered to detect the presence or absence of fluid flow in pipes, tanks, or vessels, making it an essential tool for monitoring system performance and preventing potential equipment damage.
The FS7-4E Flow Switch features a durable, corrosion-resistant 316L stainless steel body, ensuring long-lasting operation even in harsh and corrosive environments. Its compact design allows for easy installation and maintenance, while its NEMA 7/Class I, Division 2, Group D, T4 compliant explosion-proof enclosure provides an additional layer of safety in potentially hazardous areas.
The flow switch operates on a positive-displacement principle, utilizing a gear mechanism to precisely measure fluid flow. This design offers excellent sensitivity, even with low flow rates, and is virtually unaffected by changes in fluid viscosity, temperature, or pressure. The FS7-4E can be configured for both normally open (NO) and normally closed (NC) contact options, making it versatile for a wide range of applications.
The McDonnell Miller FS7-4E Flow Switch is designed for use with a wide variety of fluids, including water, oil, and other non-conductive liquids. It is available in different flow rates, including 0.05, 0.1, 0.2, 0.5, 1, and 2 gallons per minute (GPM), ensuring that you can find the perfect fit for your specific application requirements.
In summary, the McDonnell Miller FS7-4E Flow Switch with Explosion-Proof Design is an exceptional choice for monitoring fluid flow in potentially hazardous industrial environments. Its robust construction, versatile configuration options, and superior performance make it an essential tool for ensuring system efficiency and safety.
