    Bronkhorst® 3.2.3 Switching control function Bronkhorst® software automatically adds additional communication channels to the array as regular instruments. Control functions The multi-parameter functionality enables simultaneous measurement of flow, upstream pressure and downstream pressure, using 3 different communication channels. The selected control function determines whether the instrument uses 1 or 2 communication channels/sensors for measurement and control.

    Adjusting zero point Zero-stability The zero point of a Bronkhorst® flow meter/controller (the measurement signal that indicates the absence of a flow) is factory adjusted at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned upright. Under normal circumstances (i.e. at stable process conditions), the zero point will remain stable. However, over time several factors can induce a slight deviation of the measured value from the zero point, causing the instrument to detect a flow when in reality there is none.

  • Page 19: Maintenance

    To track down problems in the fluid system, depressurize the fluid system and disconnect the suspected unit from the process line. Dirt or clogging might be quickly detected by visual inspection of disassembled fluid connections. If you suspect leakage, do not disassemble the device for inspection, but contact your Bronkhorst representative for service or repairs.
