Background
In August 2025, a leading technical company based in Portugal specializing in scientific instrumentation reached out with a specific requirement: a high-precision mass flow controller for liquid CO₂ used in controlled laboratory and pilot-scale applications.
The working conditions were challenging:
Medium: Liquid CO₂
Flow Rate: 500 g/min
Operating Pressure: 50–60 bar
Temperature: 5–10°C
Signal: 4–20mA with Modbus RTU (RS485)
Fitting: 1/4″ compression connection
Solution Provided
After a series of technical evaluations and dimensional consultations, our engineering team recommended the ACU20FEH-LC model from the ACU20FE Series Coriolis mass flow controller line.
Key features delivered:
±0.25% full-scale accuracy for liquids
Rapid response time under 0.2s
High stability under vibration, with optional mass block
Factory-configured 1/4” compression fitting for seamless installation
Compact footprint with remote mounting option
Reliable communication via RS485 Modbus RTU
A customized technical drawing was provided to support pre-installation planning, and our proposal included DHL express delivery to the client’s facility in northern Portugal.
Outcome
The client confirmed the order in early August 2025. Production was arranged immediately upon order confirmation, with testing and calibration according to application conditions. The mass flow controller is expected to play a critical role in improving the reliability and control precision of the customer’s liquid CO₂ handling system.
Significance
This project reflects our capability to respond quickly to customized small-flow, high-pressure measurement needs — especially in the European market where CO₂, hydrogen, and specialty gases are increasingly used in R&D and clean energy applications.
We look forward to building long-term collaboration with more clients across Portugal and the broader EU region.
