Detailed Product Description


Teltech Extended Counter Drives have been specially designedforapplications where the system design either requires elevation oftheFlow Meter Mechanical Counter & Preset Register forbettervisibility or to protect Counter & Preset Register componentswhenmetering hot, cold or corrosive liquids.

DESIGN FEATURES

  • Positive low friction drive.
  • Extension length up to 3810 mm.
  • Choiceof fixed Counter mounting in any one of the 16 pre-determinedangles or3600 free bi-directional rotation by swivel, even duringoperation.
  • Provision of Preset Register fitment for Preset Valve control through an adjustable linkage.
    Provision for thermal barrier.


PRINCIPLES OF OPERATION


Therearetwo basic types of Extended Counter Drives. The Short Extensionwith anadaptor height of 150 mm & the Long Extension which can besuppliedup to a height of 3810 mm. The Short Extension version isgenerallyrecommended for metering applications involving hot, cold orcorrosiveliquids. It consists of an adaptor casting having a spindlewhichtransmits the drive from the Flow Meter Calibrating Mechanism totheCounter. A bakelite plate fitted on the top of the CalibratingMechanismbase acts as the thermal barrier.

Thelongextension version is mainly used when operational &spacerequirements necessitate elevation of the Counter forbettervisibility. In this case, the drive to the Counter from the FlowMeterCalibrating Mechanism is by a steel coupling shaft, supported atbothends & housed in a steel tube for a smooth lowfrictiontransmission. The Counter can have a fixed or swivelmountingarrangement. For batching operation, fitment of a PresetRegister ispossible with valve control through an adjustable linkage.



APPLICATIONS

  • Easier visibility in gantry operations where Flow Meter is located at ground level.
  • Protection of Flow Meter Counter & Preset Register from corrosive liquid vapours.
  • Protection of Meter Counter, from heat or cold, when metering liquidsat extreme temperatures.
