Summary of Contents for Casella STORM Guardian

  • Page 1 The copyright in this document which contains proprietary information is vested in CASELLA. The contents of this document must not be used for purposes other than that for which it has been supplied or reproduced or disclosed wholly or in part...
  • Page 3 Introduction Casella Tipping Bucket Rain Gauges are reliable and extremely robust devices. When paired with a Casella LOG 8 telemetry data logger they have the ability to take measurements from a single or a multi-parameter sensor at regular intervals, and stores this data in internal memory.
  • Page 4: Principle Of Operation

    Principle of Operation The rain gauges comprise a light weight injection moulded plastic divided .tipping bucket. assembly with stainless steel pivot pins that rest upon stainless steel pins in the support assembly. The use of pins produces a rolling rather than pivoting motion when the bucket tips, which reduces the likelihood of friction.
  • Page 5: Preparation For Use

    Construction The rain gauge is manufactured entirely from non-corrosive materials. The base and septum ring are cast in Aluminium Alloy LM25, heat treated and protectively coated. The outer ring and funnel are fabricated from aluminium alloy sheet and again protectively coated. Stainless steel mesh is employed to protect the inlet and outlet ports from the ingress of foreign bodies.
  • Page 6 Release the two catches securing the outer cover to the base and then carefully lift off the cover. Feed a suitable length of 2 A, 2-core cable, through the grommet. Connect the instrument end of this cable to the terminal block provided on the underside of the base unit for the output signal.
  • Page 7: Maintenance

    A restriction, such as an elastic band, may have been fitted to prevent the bucket from moving during transit. Carefully remove any restriction and check that the bucket pivots freely. Replace the outer cover of standard versions, with the catches engaged in the cutouts in the base plate.
  • Page 8 For fast counter inputs, some form of capacitor-resistor filtering may be necessary to reduce bounce effects in the contact signal. For details of suitable logging devices please contact the Casella sales department. Please go through these procedures before you go to site.
