    Exemption from liability Kirchner und Tochter accepts no liability for any damage or interruptions of operation resulting from human error, failure to comply with these installation and operating instructions, improper performance of installation and repair work, use of spare parts other than those from the original manufacturers or use of the KFS devices other than for the intended purpose.

  • Page 5: Intended Use

    Flap-type flow meters Intended use The KFS devices are designed and intended for measuring the flow of liquids and gases. They may only be installed between flanges in the pipeline. Select the KFS device model on the basis of the nominal diameter and nominal pressure at the site and also the kind of fluid product concerned;...

  • Page 6: Note For The Use Of Equipment In Ex-Proof Version

    In accordance with the law concerning handling of waste (critical waste) and the hazardous materials directive (general duty to protect), we would point out that all flow meters returned to Kirchner und Tochter for repair are required to be free from any and all hazardous substances (alkaline solutions, acids, solvents, etc.).

  • Page 7: Installation, Start-Up And Maintenance Of The Mechanical Part

    Flap-type flow meters Installation, start-up and maintenance of the mechanical part Preparatory work Have ready flanges and fastening materials as specified in EN 1092-1 for mounting the device between flanges. Between the flanges, include a distance of ring thickness plus 4 mm for the gaskets. Refer to assembly dimensions in sect.

  • Page 8: Start-Up

    Start-up Pressurize the measuring pipeline. Avoid water hammer or flow separation. Check the flange connections for leak-tightness and retighten bolted connections if necessary. Test the local indicator on the device with varying volumetric flow rates, starting with the maximum value. Maintenance The device is normally maintenance-free.
  • Page 9 Flap-type flow meters Do not change the original orientation of the flap (maintaining the direction of rotation appropriate to the indicator part ). The flap requires a minimum of 1 mm clearance on both sides (risk of jamming and sparking). Hazardous areas: Do not on any account remove the labelling on the scale casing containing information on explosion protection.
