Measuring technology for flow rate, mass flow rate and flow velocity
Measuring tube TA Di with inside diameter 8, 16, 21.6, 27.2, 35.9 and 41.8 mm and transducer U10b in sensor connection housing. Via web interface, measuring instruments having a WiFi interface can be accessed by a web-enabled device, performance data can be checked and transferred and the device settings can be customised according to the measuring task. The unit can be used for a variety of gases even in ex-applications categories 3G and 3D (zone 2 and zone 22) That way there is no need for recalibration or return to the manufacturer when there’s a change of gas. The corresponding gas characteristics stored in the device simply have to be selected on the sensor.
