Frequently Asked Questions

What is the McDonnell & Miller 3G-OTH-02716 flow switch used for?

The McDonnell & Miller 3G-OTH-02716 flow switch is used to detect liquid flow or no-flow conditions in industrial piping systems. It is commonly applied in HVAC, boiler, and process control systems to protect equipment by actuating alarms or shutting down pumps when flow stops.

What are the specifications of the McDonnell & Miller 3G-OTH-02716 flow switch?

The 3G-OTH-02716 features an in-line configuration that eliminates the need for a pipe tee, offers very high flow capacity, and actuates at extremely low flow rates. It is available in sizes including 3/4 NPT and 1 NPT. For exact pressure and temperature ratings, consult the manufacturer's datasheet.

Where to buy the McDonnell & Miller 3G-OTH-02716 in Singapore?

You can source the McDonnell & Miller 3G-OTH-02716 flow switch through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for a quotation and lead time on this item.

How to install the McDonnell & Miller 3G-OTH-02716 flow switch?

Install the 3G-OTH-02716 in a horizontal pipe section with the flow arrow aligned to the direction of flow. Ensure the pipe is fully drained before installation. Use thread sealant on NPT connections and avoid overtightening. Always follow the manufacturer's installation manual for proper electrical wiring and adjustment.
