The flow meter has a measurement range of 0 - 30 m/s. In addition to the air flow, the flow meter can reliably determine the ambient temperature between -20 to 60 Â°C and the ambient humidity between 0 to 100 % RH. The telescopic arm can be extended up to a length of 390 mm. This makes the flow meter part of the basic equipment of a ventilation technician for regulating and controlling ventilation systems. The flow meter can be connected to an Android or iOS device via the Bluetooth 4.0 data interface. With the free app all sensors can be read from the flow meter. In addition to the normal view of all measuring parameters from the flow meter, the measured values can also be displayed graphically. Another function is the app's data recording. This saves all measured values that have been measured by the flow meter directly. After a measurement, you can export data as a CSV file.This text is machine translated.
