A 316L stainless steel, 3A/EHEDG approved, 30 Ra Finish (0.8 μm) compact and drainable Coriolis flow meter that is ideal for hygienic applications that require a highly reliable, repeatable and robust measurement.
The basic operation of Coriolis flow meters is based on the principles of motion mechanics. As fluid moves through a vibrating tube it is forced to accelerate as it moves toward the point of peak-amplitude vibration. Conversely, decelerating fluid moves away from the point of peak amplitude as it exits the tube. The result is a twisting reaction of the flow tube during flowing conditions as it traverses each vibration cycle.
A Coriolis meter is based on the principles of motion mechanics. When the process fluid enters the sensor, it is split. During operation, a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency. As the tubes oscillate, the voltage generated from each pickoff creates a sine wave. This indicates the motion of one tube relative to the other. The time delay between the two sine waves is called Delta-T, which is directly proportional to the mass flow rate.
Coriolis flow meters are extremely important in a multitude of flow-measurement applications. Offering a wide breadth of line sizes, flow measurement accuracy and turndown, these meters support many industries and can measure flow rates from a few grams/hour up to 120,000 lbs/minute. Coriolis meters have a wide, dynamic range due to the linear nature of the signal created while measuring flow.
Coriolis flow meters are used in a wide range of critical, challenging applications, in industries including oil and gas, water and wastewater, power, chemical, food and beverage, and life sciences.
