Is a vortex flow meter a mass flow meter?

Project Overview

The vortex mass flowmeter is actually not a mass flowmeter. The two flowmeters are completely different. Their working principles are different, so there is no subsidiary relationship between them, but in terms of performance It is said that the vortex mass flowmeter is better than the mass flowmeter, and the cost-effectiveness of the vortex mass flowmeter is also higher:

1. Vortex flowmeter

(1) Definition : Vortex flowmeter is a volume flowmeter that is researched and produced based on the Karman vortex principle to measure the volume flow rate of gas, steam or liquid, the volume flow rate under standard conditions or the mass flow rate. It is mainly used for flow measurement of industrial pipeline media fluids, such as gas, liquid, steam and other media.

(2) Features:

1. Small pressure loss, large measuring range and high precision.

2. When measuring the volume flow rate under working conditions, it is almost not affected by parameters such as fluid density, pressure, temperature, viscosity and so on.

3. There are no moving mechanical parts, so it has high reliability and low maintenance.

4. The instrument parameters can be stable for a long time.

5. It adopts piezoelectric stress sensor, which has high reliability and can work in the operating temperature range of -20℃~+250℃.

6. It has analog standard signal and digital pulse signal output, which is easy to be used with digital systems such as computers.

(3) Application: Vortex flowmeters are widely used in petroleum, natural gas, chemical industry and other fields.

2. Mass flow meter

(1) Definition: A mass flow meter is an instrument that measures the mass flow of a fluid. It can directly measure the mass flow of the fluid without measuring the volume. Convert.

(2) Features:

1. High precision, high reliability, high stability and low maintenance.

2. The principle is based on the Coriolis force principle. The mass flow rate of the fluid is obtained by measuring the Coriolis force experienced by the fluid when flowing in the pipeline.

(3) Application: Mass flow meters are widely used in flow measurement and control in chemical, petroleum, food, pharmaceutical and other industries.

Both vortex flowmeters and mass flowmeters play an important role in the field of flow measurement. They are different in measurement principles, characteristics, and application ranges, but they are important in flow measurement and have a wide range of applications. , high-precision measurement, intelligence and digitalization trends, and the need for regular calibration and maintenance. These similarities reflect the commonality and development trends of flow measurement technology.
