E+H Dosimass Coriolis Flowmeter

Precision Flow Measurement for Demanding Batching Applications

The Endress+Hauser Dosimass Coriolis Flowmeter delivers unmatched accuracy and reliability for liquid and gas flow measurement in automated dosing and filling systems. Operating independently of fluid physical properties such as viscosity, density, temperature, and pressure, the Dosimass ensures consistent performance across diverse media. Designed with a highly compact transmitter and robust sensor housing, this flowmeter integrates seamlessly into tight piping architectures without performance degradation.

Advanced Multivariable Measurement Principle

At the core of the Dosimass is the proven Coriolis measuring principle. As fluid travels through the oscillating measuring tubes, generated Coriolis forces create a measurable phase shift proportional to the mass flow rate. Beyond mass flow, the continuous excitation at resonance frequency enables real-time fluid density calculation, while an integrated sensor measures process temperature. By delivering multivariable measurement (mass flow, volume flow, density, and temperature) in a single instrument, the Dosimass minimizes line penetrations and reduces total installation complexity.

Hygienic Design & Versatile System Integration

Engineered to meet stringent global standards, the wetted parts of the Dosimass flowmeter are CIP (Clean-in-Place) and SIP (Steam-in-Place) cleanable up to +150°C (+302°F). With available hygienic process connections such as Tri-Clamp, DIN 11851, and DIN 11864-1, the device fulfills strict hygienic requirements for food, beverage, and life science applications. For digital communication and process automation, the meter supports flexible digital interfaces including IO-Link, Modbus RS485, and configurable pulse/frequency/switch outputs.

Optimized for High-Speed Dosing Systems

The Dosimass is engineered specifically to eliminate measurement errors during rapid cycling. With excellent zero-point stability and fast response times, it achieves high dosing repeatability (up to ±0.05% for dosing times > 3 s). Because the Coriolis principle functions without straight inlet or outlet piping runs, engineers can install the meter directly upstream of filling valves, maximizing space efficiency on linear and circular filling machines.

Applications

• Filling & Batching Machines: Linear and circular automated container filling systems.

• Hygienic Dosing: Precise liquid dosing in food, beverage, and pharmaceutical processes.

• Chemical Blending: Multi-component liquid blending requiring density and flow monitoring.

• Gas & Liquid Measurement: High-repeatability metering of fluids independent of viscosity changes.

Technical Specifications

FAQ 

Q1: Does the Endress+Hauser Dosimass require straight inlet and outlet runs? A: No, turbulence-creating fittings such as valves, elbows, or T-pieces do not affect measurement performance as long as no cavitation occurs. This allows for extremely compact installation.

Q2: Can the Dosimass flowmeter be cleaned in place (CIP/SIP)? A: Yes, the wetted materials are fully CIP and SIP cleanable, supporting cleaning temperatures up to +150°C (+302°F) for up to 60 minutes.

Q3: Is field zero-point adjustment required before operation? A: All Dosimass devices are calibrated under standard reference conditions prior to delivery. Zero adjustment is generally not required, except under extreme operating conditions or very low flow rates.
