1. What are the types of mass flow meters?

2. What is the difference between vortex flow meters and electromagnetic flow meters?

The difference between vortex flow meters and electromagnetic flow meters is as follows:

1. Measurement principle: Vortex flow meters use the phenomenon of vortex generated by vortex blades flowing with the fluid to calculate the flow rate of the fluid by measuring the rotation frequency or speed of the vortex blades.. Electromagnetic flowmeter: Using the principle of electromagnetic induction, it measures the electromotive force experienced by a conductive fluid flowing in a magnetic field, thereby measuring the flow rate of the fluid. From the perspective of the original pronunciation, the difference between the two is obvious.

2. Structural form: Vortex flowmeter: composed of vortex generator, piezoelectric element, guide element and magnetic circuit part.

. The transmitter housing is made of steel plate or aluminum alloy plate by integral die-casting, and the body and sensor are combined into an integrated unit instrument. Electromagnetic flowmeter: composed of a conductive tube, excitation coil, housing, and electrodes, with secondary meters installed at the upper and lower ends of the electrodes.

III. Vortex flowmeter: it is mainly used to measure the flow of liquid, steam and gas, but it is not applicable to viscous liquid, granular solid medium and liquid containing foam and bubbles. Electromagnetic flowmeter: suitable for measuring the flow rate of various conductive liquids, but cannot measure non-conductive media.

Fourth, output signal vortex flowmeter: usually outputs a standard current signal of 4-20mA.

. Electromagnetic flow What is a vortex flowmeter

meter: outputting a linear signal proportional to the flow rate. In summary, there are significant differences between vortex flowmeters and electromagnetic flowmeters in terms of measurement principles, structural forms, usage scenarios, and output signals. In practical applications, the appropriate type of flowmeter should be selected based on factors such as the properties of the measured fluid, measurement requirements, and usage environment.

3. Introduction to Vortex Flow Meter

Vortex flow meter is researched and produced based on the Karman vortex principle, mainly used for flow measurement of industrial pipeline media fluids, such as gas, liquid, vapor and other media.

. Below, we will introduce the principle and other related characteristics of vortex flowmeter for your reference.

1. Working Principle: A vortex flowmeter is a type of flowmeter designed and manufactured using the Karman vortex principle and contemporary electronic technology. The frequency of vortex generation is proportional to the velocity of the fluid, and under certain conditions, it satisfies the following equation: f=St * v/d (where f: vortex generation frequency v: flow velocity d: triangular column width St: Strouhal number). The fluid vortex generates alternating pressure on the triangular column, which is detected by a piezoelectric signal sensor as an electrical signal and amplified by a preamplifier to become a standard electrical signal output.

. The VA series vortex flowmeter can measure the volume of a wide range of gases (including steam) and liquids, and can be paired with a flow accumulator and temperature and pressure sensors for mass calculation and various parameter display.
