DFL-1/DFL-5 (online float-type density meter for high-resolution liquid measurement)

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

DFL-1

DFL-5

Ultra-high-resolution fluid measurement densitometer DFL-1

Features

  • Online densitometer for high-sensitivity measurement of fluid density.
    Ultra-high-resolution density measurement with a maximum sensitivity of 0.00005 g/cm3.
    Density measurement can be used to determine the quality and purity of the measured fluid and the degree to which reactions have progressed.
  • Measurement is performed by converting float buoyancy into air pressure, requiring no electricity.
  • Function for automatically compensating for changes in density due to increases or decreases in measured fluid temperature.
  • Capable of measuring pressurized fluids.
    Wet measurement method capable of measuring at pressures of up to 1.961 MPa (20 kgf/cm2).
  • Simple balance scale design and structure makes maintenance easy.
  • Product lifespan of approximately 30 years.Excellent return on investment.
  • Tried and tested, with a track record of over 2,100 units sold since 1970.

Ultra-high-resolution fluid measurement densitometer DFL-5
