The Venturi tube is a primary element for volume measurement in pipelines. The principle of the Ventur tube allows measurements with all media. The venturi tube described here is especially designed for air volume measurements in ventilation ducts. The installation of the venturi tube in the system is to be carried out using plug-in sleeves with corresponding lip seals. A version with flanges is also available.
The Ventur tube is a one-piece injection molded housing made of PPs. High accuracy and optimum centering by means of double-sided sleeves or flanges. The Venturi nozzle is manufactured according to DIN EN ISO 5167 with inlet profile according to ISA 1932. The flow process, which is important and favorable for the measurement, is achieved by the special deformation method of the thermoplastic material. It allows for an exact fit as well as extremely smooth surfaces for the ideal flow behavior without costly reworking.
The pressure taps have individual holes in the cylindrical part 4 - 5, which open into a ring chamber.
For further evaluation, indicators (DA2000) with a scale in m³ / h or transmitter (DS85 or DS200) are available for remote transmission of the measuring signal. The exact design of the indicators or transmitters depends on the design data, these must be clarified in advance.
