DFL-1/DFL-5 online float-type density meters

For ultra-high-resolution/high-resolution fluid measurement

DFL-1 ultra-high-resolution fluid measurement densitometer

DFL-1

  • The online densitometer for high-sensitivity measurement of fluid density.
    Ultra-high-resolution density measurement with a maximum sensitivity of 0.00005 g/cm³.
    The density measurement determines the quality and purity of measured fluids and the degree to which reactions have progressed.
  • Measurement is performed by the converting float buoyancy into air pressure, requiring no electricity.
  • The function of automatic compensating performs for the changing density caused by increases or decreases in measured fluids temperature.
  • Available to measuring pressurized fluids.
    Wet measurement method available to measuring at pressures of up to 1.961 MPa (20 kgf/cm²).
  • Simple balance scale design and structure for easy maintenance.
  • Track records have been over 2,100 units since 1970.
