DESCRIPTION

The electrical functioning of the flow sensor is based on the calorimetric principle. The temperature of the measurement sensor is raised from its interior with some degrees Celsius in relation to the temperature of the flowing medium into which the sensor is projecting. When the medium is flowing, the heat produced in the sensor is dissipated through the medium, i.e. the sensor is cooled down.

The temperature that ensues in the sensor is measured and compared to the registered medium temperature. The state of flow of the medium can be derived from the registered temperature difference.

TECHNICAL FEATURES

• Registration range from 1...150cm/s up to 2...30m/s
• Output as NPN - transistor, 24VDC / 400mA
• Integrated electronics
• One-piece stainless steel, resistance to pressure up to 100bar
• Balancing display 6 LEDs (red, yellow, green)
• Degree of protection IP67

APPLICATION

With the flow measurement technology from octogon, even the smallest flows are recorded quickly and with high precision using the calorimetric measuring principle. The flow sensors and flow monitors are intended for use in applications in which flow is required as a trend indicator, including in air conditioning, ventilation and heating technology and in many industrial areas.

Heating, ventilation and air conditioning systems, fire extinguishing systems, aggregates, extractor hoods, filter monitoring, process control, fuel cells and gas measuring stations are further application examples of our flow sensors.
