Micro-Flow Coriolis Mass Flow Meter | Chemical Dosing

Product Description

In fine chemical processing, additive dosing, and pilot-scale trials, achieving high-precision mass flow measurement of corrosive media in confined spaces is critical for process stability and safety. The COLISEN DN08 ultra-compact U-tube Coriolis mass flow meter - even smaller than micro-bend models - is specifically designed for tight installations, making it an ideal solution for low-flow chemical applications.

Key Challenges & Solutions

1. Installation in Tight Spaces

Challenge: Traditional flow meters are too bulky for compact piping or equipment interiors. Solution: Ultra-compact U-tube design - even smaller than micro-bend tubes - fits easily into restricted areas.

2. High Accuracy at Low Flow

Challenge: Low-flow chemicals (e.g., additives, catalysts) are hard to measure precisely. Solution: Zero stability <0.002 kg/min, maintains 0.15% accuracy down to 20 kg/min.

3. Corrosive Media Compatibility

Challenge: Acids, alkalis, solvents can damage measuring tubes. Solution: Wetted parts in 316L / Hastelloy C, excellent corrosion resistance.

4. Explosion-Proof & Reliability

Challenge: Flammable gases present in chemical plants require high safety ratings. Solution: Ex d ib IIC T6 Gb certified, no moving parts, maintenance-free.
