Thermal flow switches are sensors with an electrical contact output at a specific flow rate. Dwyer models provide a complete system for leak detection and feature a selectable NO or NC operation. Applications include chillers, hot water heaters, and liquid transfer systems.
- Series TSP
- NO or NC Relay Output, Adjustable Time Delay
Liquid Flow Controller protects pumps and valves from dry running. Combines a liquid flow switch with a fail-safe relay controller to detect a flow or no flow situation.
- Series TDS
- Adjustable Switch Point, LED Indication
Thermal Dispersion Flow Switch offers solid state flow detection of non-coating liquids for pump and process protection. Features a selectable NO or NC operation.
