    2 Safety instructions 2.1 General safety instructions FLUXUS G722ST-HT Safety instructions General safety instructions Prior to any work, read the operating instruction carefully and in full. Failure to comply with the instructions, in particular with the safety instructions, poses a risk to health and can lead to material damages.

  • Page 9: Intended Use

    2 Safety instructions FLUXUS G722ST-HT 2.2 Intended use Intended use The measuring equipment is intended for the measurement of fluid properties in closed pipes. The connected transducers measure the average flow velocity of the fluid. The transmitter uses these values to calculate the sought quantities, e.g., volumetric flow rate and mass flow rate. Through comparison with the values stored in the transmitter further physical quantities can be determined.

    2 Safety instructions 2.7 Safety instructions for transport FLUXUS G722ST-HT marked as a disconnecting device for the transmitter. It should be located near the transmitter. If the transmitter is used in an explosive atmosphere, the equipment switch has to be installed outside the explosive atmosphere. If this is not possible, it has to be installed in the least hazardous area.
