Density and Concentration Meter DIMF 2.1

The Bopp & Reuther DIMF 2.1 Density and Concentration Meter delivers high-precision monitoring of liquid density and concentration using the proven tuning-fork principle. Designed for continuous operation, it provides exceptional accuracy (better than ±0.02 %), superior repeatability, and long-term stability — even under demanding industrial conditions.

Crafted from robust stainless steel 1.4571 / 316 Ti, the DIMF 2.1 ensures reliable measurement in processes involving high pressure (up to 40 bar) and temperature (up to 150 °C). It continuously measures density, concentration, °Brix, °Plato, or mass flow-related values, enabling real-time quality assurance and process control in chemical, petrochemical, beverage, and energy industries.

With intrinsically safe or flameproof designs and flexible output options such as 4-20 mA, PT100, and external interface compatibility (UR 06 series), the DIMF 2.1 integrates seamlessly into modern control systems — offering dependable, maintenance-free performance for critical measurement tasks.
