Features

  • Built-in lithium batteries (No external power supply is required)
  • Indications of both instantaneous flow-rate and integrating flow volume by only 1 flowmeter
  • Revolving display unit (It can be fixed to a easy-to-read position)
  • Simplified structure with the vane wheel type measuring principle
  • Measurement of various liquids
  • Reset function for indications of Integrating Flow Volume (Total) and Integrating Flow Volume (Trip)
  • Value holding function for Instantaneous Flow-Rate indication
  • Pulse output function (Option)
