Description
The Dwyer V4-2-U-MT is part of the trusted FLOTECT V4 Series Vane-Operated Flow Switch, engineered to provide dependable flow detection in liquid piping systems commonly found in HVAC, hydronic heating and cooling, chiller, and process control applications. When flow is present, the paddle vane deflects and actuates the internal switch mechanism, providing a clear electrical signal to downstream controls or safety circuits.
Key Features
- Vane-operated design for accurate and repeatable liquid flow detection
- Suitable for use in HVAC hydronic systems, chillers, cooling towers, and process piping
- Snap-action switch mechanism for reliable on/off switching
- Compact, insertion-style body for straightforward pipe installation
- Durable construction designed to withstand the demands of commercial and industrial environments
- Can be used as a safety interlock to protect pumps, boilers, and chillers from low-flow or no-flow conditions
Typical Applications
- Chiller and boiler flow proving
- Pump protection and flow verification
- Cooling tower and heat exchanger systems
- Hydronic heating and cooling loops
- Process water and industrial fluid monitoring
