DO620 flowmeter Flow measurement based on vortex frequency

The DO620 is a flowmeter that measures flow based on the frequency of vortex occurrence. This flowmeter is suitable for single-phase fluids or media that can be regarded as single-phase fluids. Within a specific Reynolds number range, the frequency at which AOJ (which may refer to a certain flowmeter technology or type) vortices occur is mainly related to the flow velocity of the fluid, and is almost unaffected by changes in other parameters of the flow being measured (such as temperature, pressure, density, and dynamic viscosity).

The following are some of the main technical parameters of the DO620 flowmeter:

Measuring medium: gas, liquid, vapor.
AOJ medium temperature range: room temperature to -40℃ ~ +400℃.
Nominal diameter: DN15-100.
DO620 electromagnetic flowmeter, the following are its functions and characteristics:
Function: Electromagnetic flowmeter is a flow measurement instrument based on the principle of electromagnetic induction, which can measure the flow of liquid or gas and convert the measurement results into electrical signal output.
Features: Electromagnetic flowmeter has the following characteristics:
High accuracy: The DO620 electromagnetic flowmeter has a high measurement accuracy, usually up to 0.5% or higher.
High reliability: The electromagnetic flowmeter adopts non-contact measurement, which is not affected by the fluid flow state and has high reliability.
Can measure a variety of media: DO620 electromagnetic flowmeter can measure a variety of media, such as water, sewage, oil, acid, alkali, etc.
Optional output mode: DO620 electromagnetic flowmeter can choose a variety of output modes, such as analog output, digital output, RS485 communication.
