High Precision Coriolis Mass Flowmeter 316L High Temperature Type -50~350℃

Characteristics of flowmeter
Compared with traditional flow measurement methods, flowmeter has obvious advantages
Flowmeter can directly measure the mass flow of fluid in the pipeline without the need for conversion of intermediate parameters, thus avoiding the measurement error caused by the intermediate link.
It has high mass flow measurement accuracy and good repeatability, and can achieve high-accuracy direct measurement of fluid mass flow within a relatively large range ratio.
The flowmeter can measure a wide range of fluids. In addition to measuring uniform fluids of general viscosity, it can also measure various high-viscosity and non-Newtonian fluids. It can also be used for slurries containing solid phase components and fluids containing trace gas phase components under certain conditions.

Detailed introduction of Coriolis mass flowmeter:

The Coriolis Mass Flow Meter is a meter used to measure the mass flow of liquid or gas, and its working principle is based on the Coriolis effect. Coriolis flowmeters are widely used due to their high accuracy and wide range of applications. The following is a detailed introduction to the Coriolis mass flowmeter:

Working Principle

The working principle of the Coriolis mass flowmeter is based on the Coriolis Effect, which refers to the inertial force that an object will be subject to when it moves in a rotating system. Specifically, the Coriolis flowmeter uses the following steps to measure flow:

1. **Fluid passing through the sensor**: The fluid flows in the sensor of the flowmeter, usually through a pair of vibrating tubes or vibrating elements.

2. **Vibration of the vibrating tube**: The vibrating tubes of the flowmeter are forced to vibrate at a certain frequency and amplitude. The fluid exerts force on these vibrating tubes during the flow process.

3. **Generation of Coriolis force**: When the fluid flows through the vibrating tube, Coriolis force is generated due to the inertia of the fluid, and this force causes the vibrating tube to have a relative displacement. This displacement affects the vibration frequency and phase of the vibrating tube.

4. **Measurement and calculation**: The sensor detects the relative displacement and frequency change of the vibrating tube and converts these signals into mass flow values. By analyzing the vibration characteristics of the vibrating tube, the flow meter can directly calculate the mass flow of the fluid without considering the density and temperature changes of the fluid.

Main features

- **High accuracy**: Coriolis flowmeters provide very high measurement accuracy, which can reach 0.1% or even higher.

- **Direct measurement of mass flow**: The mass flow of the fluid can be measured directly without converting the relationship between volume flow and density.

- **Wide applicability**: Suitable for flow measurement of liquids and gases, including fluids with high viscosity, corrosiveness or high bubble content.

- **Comprehensive functions**: In addition to flow measurement, many Coriolis flowmeters can also measure other parameters such as temperature, density and concentration.

- **Less maintenance requirements**: Because the measuring part of the flowmeter has no moving mechanical parts, it is relatively less prone to wear and failure.

Application areas

- **Chemical industry**: Used to accurately measure the flow of chemicals, especially those that are highly corrosive or viscous.
- **Food and Beverage Industry**: Accurately measure liquid raw materials and products to ensure product consistency and quality.
- **Oil and Gas**: Measure the flow of oil, natural gas and their mixtures, especially in situations where high accuracy and stability are required.
- **Pharmaceutical Industry**: Used to accurately measure the flow of drugs and other critical liquids during the production process.

Overall, Coriolis mass flowmeters have become key flow measurement tools in many industrial fields due to their high accuracy, stability and versatility.

Working Principle
If a pipe is rotated around a point (P) while liquid is flowing through it (toward or away from the center of rotation), that fluid will generate an inertial force, with reference to Figure 1.1:

Sensor Structure

Mass flow meter sensor consists of measurement tube, driving device, position detector, support structure, the temperature sensor, housing, etc.
