The mass flow meter produced by our company can well solve the difficult to measure fluid problems, such as high temperature, low temperature, high pressure, high viscosity, small flow, large temperature and pressure fluctuations, user requirements, fast response time, high accuracy requirements and other actual measurement needs .
Triangle shape coriolis mass flow meter
● Triangle shap bent tube design
● For all industries, and all process and custody transfer applications.
● Universal measuring principle for liquids and gases
● Multivariable measurement- simultaneous measuring of mass flow, density, temperature
● High measuring accuracy: typically ±0.2%, ±0.1% o.r., optionally: ±0.05%
● Measuring principle independent of the physical fluid properties and the flow profile
● Easy to install (low risk of gas bubble inclusion)
● No recalibration required after fluid change
● No installation straight line necessary
● No temperature or pressure compensation necessary
● No periodical recalibration required
Coriolis flow measuring principle
Each Coriolis flowmeter has one or more measuring tubes which an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid’s inertia. Two sensors detect this change of the tube oscillation in time and space as the “phase difference.” This difference is a direct measure of the mass flow.
In addition, the fluid density can also be determined from the oscillation frequency of the measuring tubes. The temperature of the measuring tube is also registered to compensate thermal influences. The process temperature derived from this is available as an additional output signal.
Product introduction
|
Maximum process safety: unaffected by fluctuations and severe conditions. Fewer process measurement points: multivariate measurement (flow, density, temperature). Small installation space required: no straight pipe length required before and after. Mass flow measurement error: ± 0.2%, ± 0.10%, ± 0.05%. Maximum media temperature is +350 ° C (+662 ° F). The minimum medium temperature is -250 ° C (-486 ° F). Small installation space required for the transmitter: All functions are implemented in the smallest space. Time-saving on-site operation, DSP touch screen meter. Rugged, ultra-compact integrated transmitter housing. High degree of protection: IP67. |
