The new L-Dens 3300 density sensors

Density sensors for low flow rates

The new L-Dens 3300 density sensor is a powerful and flexible measuring instrument for online density measurement and concentration determination at a 3-digit accuracy. It continuously determines the density and concentration of liquids. The wide range of application programs makes the instrument extremely versatile, even for small lab production setups. W-shaped oscillating tubes made of glass enable the measurement of aggressive media such as sulphuric acid. Additionally, U-shaped tubes made of stainless steel are available.

A product-specific version of the new Pico 3000 process instrumentation controller is included for a future-orientated data management.

Density measurement with economic efficiency

Density measurement with economic efficiency

The sensors are available at a reasonable price and provide an affordable way of continuously monitoring the density and concentration of process liquids at a 3-digit accuracy. It is designed as a stand-alone sensor; therefore, there are no additional expenses for integration. The sensor is best suited for, e.g., lab reactors, pilot- or production plants.

  • Affordable way of continuous density measurement
  • 3-digit accuracy
  • Temperature-compensated density, °Brix, °Plato, %alcohol
  • API index or other concentration values
  • Stand-alone instrument
  • No expenses for integration
Low flow rates for accurate measurement

Low flow rates for accurate measurement

The U-tube which measures the density using the oscillating U-tube principle provides precise measuring values at flow rates below 80 L/h.

  • One-piece oscillating tubes made of stainless steel with an inner diameter of 2.1 mm or glass with an inner diameter of 2.0 mm
  • Flow rate 80 L/h
The right materials for the wetted parts to avoid contaminations and minimize wear and tear

The right materials for the wetted parts to avoid contaminations and minimize wear and tear

The available wetted parts made of stainless steel or glass are prepared for the use in, e.g., the petroleum, chemical, and beverage industry to withstand corrosion on the sensing element. You benefit from accurate and drift-free measurements even in difficult media. 

Wetted parts made of:

  • Stainless steel
  • Glass
No service required

No service required

L-Dens 3300 sensors do not require any service activities. They are designed without moving parts, are maintenance-free, and do not require any consumables.
