■ In-line fluid density measurement
■ High-precision density measurement
■ Possible mass flow rate measurement when used in conjunction with a volume flow rate meter
■ Has enabled density measurement in small spaces

Features

  • Density can be measured in-line, in real time.
  • For large flow rates, the flow is automatically split between the sensor cell and a bypass flow path to reduce pressure loss
  • Easy setup by simply inserting it into an existing line and then turning the power ON.
  • Simultaneous display of density and temperature
  • In combination with a volume flow meter with a dynamic range at least 1000 times greater, you can also measure mass flow rate.
  • Easy connection using digital output USB equipment
  • Mounting space for the sensor unit is now even smaller (a 40% space-saving compared to the conventional DM-100S)
  • The display unit is small-scale and lightweight (200g), so it can be panel mounted.
