FCR08-Thermal Flow Sensor

Based on thermodynamic principle, FCR08 features 2 temperature sensors inside the probe: onefor medium temperature, the other one is heated a few degrees up compared to the medium intowhich it projects. When the medium flows, the heat generated in the sensor is conducted away by the medium. The difference between these two sensors can be measured to get the flow rate.All-metal housing; 8 LEDs for switching status and flow trend display; No moving parts tominimize maintenace; Applicable to various medium.
Applications

Hydraulic/lubricating oil, cooling system

Water treatment, pump protection

Ventilation system, leak detection
