  • Page 4: Description

    Rev. A5, 10/09 • Description The FLR series instruments contain reed switches in the stem and permanent magnets in the floats. As the float rises or falls with the level of the liquid, the magnet inside the float act on the reed switch inside the stem to provide the SPST switching action.

  • Page 5: Installation

    After unpacking, visually inspect the instrument for damage. - Environment - The FLR series sensors should be installed in an areas indoor or outdoor which meets the following conditions: 1. Non-hazardous area. 2. The medium temperature does not exceed -40...
  • Page 6 • Installation - Location - Do not locate the FLR series sensor near inlets/outlets. If there is surface wave action, then use a time-delay relay or stilling tube. If a stilling tube is used, drill vent holes in the tube and use a spacer to assure the float has free travel inside the tube.
