Coriolis Mass Flow Meter Explosion-Proof is used across a wide range of industrial applications, including the food, pharmaceutical, oil, gas, petrochemical, and even natural sciences sectors.
Coriolis flow meters are capable of measuring most fluids in partial, slurry, and high-viscosity cases, including detergents, vegetable and animal oils, crude oil, plant syrups, alcohols, and even gases.
Simultaneous measurement of mass flow, density, and temperature by Coriolis mass flow meters opens up new possibilities for improving industrial process control, enhancing product quality monitoring, and ensuring greater operational safety.
Sizes of the Coriolis Mass Flow Meter Explosion-Proof
PrismaTech Coriolis mass flow meters are available in various sizes ranging from DN 8 to DN 150. The measuring tubes are made of stainless steel AISI 316L. These flow meters are equipped with an ARM Cortex M7 processor and a 320×240 TFT LCD display.
In the mechanical structure of the Coriolis mass flow meter with a dual U-shaped tube design, there is an electromagnetic actuator positioned at the center of the tubes and two velocity sensors located on either side. When the actuator is properly controlled, the tubes begin to oscillate at their structural resonance frequency.
By measuring the vibration frequency and performing temperature calibration, the density of the fluid passing through the U-shaped tubes can be determined with high accuracy. Meanwhile, as the fluid flows through the tubes, a phase difference develops between the two sensors, and the magnitude of this difference is proportional to the mass flow rate. Therefore, by measuring the phase shift between the magnetic sensors, the mass flow rate can be precisely determined. With both mass flow and density known, the volumetric flow can also be calculated.
