Dwyer Series TDS Thermal Dispersion Flow Switch | Highlight
Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators, and Water Meters. Mass Flowmeters, Controllers, Flow Indicators, and Controllers are ideal for the measurement of flow rates. Flow Switches come as a paddle, thermal, piezo, and shuttle/piston. Flow Switch Sensors with an electrical contact output at a specific flow rate have different types of switches, which are a paddle, thermal, piezo, and shuttle/piston.
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.
The Series TDS Thermal Dispersion Flow Switch offers solid-state flow detection of non-coating liquids for pump and process protection. SPDT output allows for interfacing with remote PLC or relays control devices. The adjustable switch point is factory calibrated at 0.2 fps with LED indication of flow and calibration status. Units feature selectable NO or NC operation and are not damaged by over-ranging flow velocities.
