  • Page 12: Mounting

    ® 2.4 Mounting The mounting position depends on the type of meter. The preferred position is horizontal and at high pressures (> 10 bar), Bronkhorst strongly advices to mount the instrument in this position. Avoid installation ® in close proximity of mechanic vibration and/or heat sources.

  • Page 13: Piping

    BRONKHORST ® 2.7 Piping BE SURE THAT PIPING IS ABSOLUTELY CLEAN! DO NOT install small diameter piping on high flowrates, because the inlet jetflow will affect the accuracy. DO NOT mount abrupt angles direct on in- and outlet, especially not on high flow rates. We recommend at least 10 pipe diameters distance between the angle and the instrument.

  • Page 14: Supply Pressure

    BRONKHORST ® 2.10 Supply pressure Do not apply pressure until electrical connections are made. When applying pressure to the system, take care to avoid pressure shocks in the system and increase pressure gradually, especially on high pressure units incorporating a membrane/piston operated control valve.

  • Page 19: Troubleshooting

    BRONKHORST ® 6 TROUBLESHOOTING 6.1 General For a correct analysis of the proper operation of a mass flow meter/controller it is recommended to remove the unit from the process line and to check it without applying gas supply pressure. In case the unit is dirty, this can be ascertained immediately by loosening the compression type couplings and, if applicable, the flange on the inlet side.
