Measuring technology for flow rate, mass flow rate and flow velocity
Thermal flow sensor in probe design with shaft diameter 10 mm and transducer U10b integrated in the connection housing. For applications in pipes with inside diameter from 25 mm.
Measuring instruments having a WiFi interface can be accessed by a web-enabled device via the web interface. It is also possible to check and transfer performance data and to change the device settings. With this new generation of sensors the same unit can be used for a variety of gases also in ex-applications categories 3G and 3D (zone 2 and zone 22). Recalibration or return to the manufacturer when there’s a change of gas won’t be necessary anymore. Only the adequate gas characteristics stored in the device have to be set on the sensor.
Probe material: stainless steel.
Working temperature range -10 ... +140 °C.
Pressure resistance up to 16 bar.
Measuring of air/gas velocity, compressed air and gas consumption, leakage flows, laminar flow in clean rooms or machines, in outgoing air, burner supply air, in HVAC systems and air in the low vacuum range at pressures greater than 200 hPa absolute.
Configurable via an optional keypad in the housing lid or via WiF interface.
