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.

Two free adjustable analog outputs 4-20 mA, relay output (limit value or quantity pulse), M-Bus output.  Power supply 24 V DC. Configurable via an optional keypad in the housing lid or via WiFi interface.

This principle of measurement is also referred to as the transit time difference method. For measuring the flow rate of liquids using this technique, ultrasonic pulses are sent and received simultaneously through the medium in the direction of flow and against it. The sensors work alternately as transmitter and receiver. The transit time of the acoustic signals filtered through the medium in the direction of flow is shorter than that against it. The difference in transit time Δt is measured and can be used to calculate the average flow velocity of liquids filtering through the acoustic path. After measuring the flow velocity and with the pipe cross-sectional area, volumetric flow can be calculated.
