Bopp & Reuther Density and Concentration Meter Series DIMF 2.1 TVS

Compact and intelligent density and concentration meter based on the oscillating U-tube principle with a 2-wire TR24 transmitter. The Bopp & Reuther DIMF 2.1 TVS provides high-accuracy liquid density and concentration measurement with advanced diagnostics and flexible industrial integration.

The Bopp & Reuther DIMF 2.1 TVS is a state-of-the-art density and concentration meter that uses the oscillating U-tube principle to provide precise, stable, and reliable measurement of liquids in process industries. Equipped with the new 2-wire TR24 transmitter, this compact device combines superior performance, low power consumption, and user-friendly operation in a durable design.

Offering a measuring accuracy of up to ±0.02% (±0.2 kg/m³), the DIMF 2.1 TVS delivers consistent results for a wide range of liquid applications — from chemical mixtures to liquefied gases and food-grade solutions. The integrated LCD graphic display with backlight and plain-text menu navigation ensures intuitive setup and operation, while its diagnostic functions continuously monitor temperature, sensor condition, and power supply for optimal performance.

Built with a stainless-steel (1.4571) housing and corrosion-resistant wetted materials such as Hastelloy, this instrument withstands demanding process environments up to 150 °C and 40 bar. Its seal-free design eliminates leakage risks, providing long-term measurement stability and minimal maintenance.

The DIMF 2.1 TVS supports 4–20 mA analog output and NAMUR frequency/switching output, enabling seamless integration into process control systems. Ideal for monitoring, quality control, and concentration measurement, it ensures dependable operation in both standard and safety-critical applications.
