Potential-Free Relay Output: Features a changeover (SPDT) contact for direct switching of AC or DC loads.
Thermodynamic Measurement: No moving parts in the flow stream prevents mechanical wear and clogging in “dirty” media.
Industrial Cooling Towers: Monitoring water circulation in AC-powered large-scale cooling systems.
Pump Protection: Protecting high-value pumps from dry-running damage by providing an automatic shutdown signal.
Wastewater Treatment: Reliable flow detection in systems containing sediment that would jam mechanical flow switches.
