Mass Flow

Using mass flow principles of operation, Dakota's mass flow products are unaffected by temperature and pressure variations within stated limitations. Metered gases are divided into two laminar flow paths, one through the primary flow conduit, and the other through a capillary sensor tubes. The flow conduits ensure laminar flows and therefore the ratio of flow rates is constant.

When flow takes places, gas carries heat from upstream to downstream of two precision temperature sensing windings. A Wheatstone bridge is used to monitor temperature dependent resistance gradients on the sensor windings which is linearly proportional to the instantaneous rate of flow.

  1. Digital Mass Flow Controller With Multi-Gas Functionality

    DPC07 Series - Differential Pressure Mass/Volumetric Flow Controllers

    DPC mass flow controllers provide the highest accuracy and fastest control of mass flow rates of process gases. Displays of Mass and Volumetric Flows, as well as Pressure and Temperature parameters and built-in Multi-Gas functionality facilitate the selection of up to 90 different gases and mixtures.

    These differential pressure mass flow controllers feature two programmable flow totalizers with batch processing mode, standard accuracy (0.5% RD + 0.2% FS), 200:1 turn down ratio and less than 150 ms response time.

    Significant savings are apparent, when comparing the cost of a single DPC embodying these features, with that of acquiring and installing multiple, application-specific devices.
