CMASS020TU Hydrogen Coriolis Mass Flowmeter
The Coriolis principle directly measures the mass flow rate of a fluid, unaffected by changes in temperature, pressure, viscosity, or other parameters.
Description
CMASS020TU Hydrogen Coriolis mass flowmeter


1.Direct Measurement of Mass Flow with Extremely High Accuracy
The Coriolis principle directly measures the mass flow rate of a fluid, unaffected by changes in temperature, pressure, viscosity, or other parameters.
2.Simultaneous Measurement of Multiple Parameters
In addition to mass flow, Coriolis flow meters can also synchronously and accurately measure fluid density and temperature, from which parameters such as concentration can be derived. One device serves multiple purposes, offering exceptional cost-effectiveness.
3.Insensitivity to Fluid State with Strong Adaptability
Whether the fluid is gaseous, liquid, or two-phase, Coriolis flow meters maintain extremely high measurement accuracy. This is particularly important for media like hydrogen, which is prone to phase changes.
4.No Moving Parts, High Reliability, and Low Maintenance
The sensor only has a vibrating tube in operation, with no moving parts such as impellers or bearings. As a result, it experiences minimal wear, has a long service life, and offers excellent long-term stability.
5.Outstanding Safety Design
316L material can effectively resist "hydrogen embrittlement" corrosion in a hydrogen environment, ensuring long-term safety.
Explosion-Proof Certification : Intrinsically safe design, suitable for highly hazardous explosive environments such as hydrogen.
High Protection : Adapts to harsh environments.

Accurately addresses many pain points in hydrogen energy measurement:
1. Resolving issues of accuracy and fairness in trade settlements
In scenarios such as fuel cell vehicles refueling at hydrogen stations and transactions between hydrogen suppliers and buyers, metering directly impacts economic benefits.
2. Addressing measurement inaccuracies caused by media variations in process control
In actual pipelines, the temperature and pressure of hydrogen can fluctuate. Traditional volumetric flow meters require complex compensation, while Coriolis flow meters offer a "one-stop solution" that directly provides the most critical mass flow rate data.
3. Enhancing reliability in safety monitoring
It not only measures flow rate but also monitors fluid density in real time. Abnormal changes in density may indicate variations in medium purity or the system entering an abnormal state (such as the introduction of other substances), serving as a crucial early warning signal for safety.
4. Reducing system complexity and total lifecycle costs
System simplification: Eliminates the need for additional installation of separate temperature and pressure transmitters, as well as flow computers for compensation, thereby saving costs, installation space, and wiring efforts.
5. Reducing maintenance costs
High reliability and low maintenance requirements minimize downtime and associated costs.
