      Determining the volume flow by funnel measurement

    The testo 417 is a anemometer with built-in Ø 100 mm vane to measure flow speed, volume flow and temperature. Volume flow is shown directly in the display. Accurate volume flow calculation thanks to easy input of duct area. In addition, it is easy to switch to the current temperature reading.

    The flow direction, i.e. drawn in or blowing, is visible in the display. Timed and multi-point mean calculation provide information on mean volume flow, flow speed and temperature readings. The optional funnel set facilitates efficient measurements at ventilator grilles and disc outlets. Min/max values can also be shown in the display. Current readings can be frozen in the display using the Hold function.

    Measurement of volumetric flow, flow velocity and temperature

    Every duct inlet and outlet should only contain the volumetric flow that according to calculations is a basic prerequisite to an efficient functional system.

    Particularly large vane anemometers are suitable for measuring the volumetric flows at duct outlets, as these integrate the flow velocity over a larger area thereby determining disturbance from the air grille (loop method).

    A volumetric flow rate funnel and a large vane are ideal when taking readings at the suction or blowing vents of air grilles and poppet valves. The entire volumetric flow is recorded with the aid of the funnel without the need for conversion on the basis of the flow velocity and area. This method of flow measurement is simple and reliable.

    The compact anemometer testo 417 with integrated flow/temperature vane (Ø 100 mm) is ideal for measuring the flow velocity, volumetric flow and temperature at duct outlets. The optional funnel set allows measurements at ventilation grilles and poppet valves.
