SMO-3209HR0R15 German Kebao liquid flowmeter

Advantages of German KOBOLD flowmeter SMO-3209HR0R15:

(1) The widely used orifice plate flowmeter has a sturdy structure, stable and reliable performance, and a long service life; (2) It has a wide range of applications, and there is currently no type of flow meter that can be compared to it; (3) Inspection

The measuring components, transmitters, and display instruments are produced by different manufacturers, facilitating economies of scale production.

Disadvantages:

(1) The measurement accuracy is generally low;

(2) Narrow range, generally only 3:1~4:1;

(3) High requirements for on-site installation conditions;

(4) High pressure loss (referring to orifice plates, nozzles, etc.).

Note: A new type of product: a balanced flowmeter developed with the introduction of NASA. The measurement accuracy of this flowmeter is 5-10 times that of traditional throttling devices, with a pressure loss of 1/3. Fast pressure recovery

Twice, the small straight pipe section can be as small as 1.5D, easy to install and use, greatly reducing the capacity consumption of fluid operation.

(1) The glass cone tube float flowmeter has a simple structure and is easy to use, but its disadvantage is low pressure resistance and a high risk of glass tube fragility; (2) Suitable for small diameters and low flow rates; .

(3) Low power loss.

The working principle of the German KOBOLD liquid flowmeter mainly calculates the flow rate by measuring the physical characteristics of the fluid flowing in the pipeline. Common liquid flow meters include vortex flow meters, electromagnetic flow meters, ultrasonic flow meters, and mass flow meters, and their respective working principles are as follows:

Vortex flowmeter: measures fluid flow velocity based on vortex effect. When the fluid passes through the sensor of the flowmeter, alternating vortex fluctuations are generated on both sides of the vortex street. These fluctuations are detected by the sensor and converted into electrical signals for output. By measuring the frequency and amplitude of the vortex fluctuations, the flow velocity and flow rate of the fluid can be calculated.

Electromagnetic flowmeter: uses the principle of electromagnetic induction to measure the flow rate of conductive fluids. When a conductive liquid passes through a pipeline, an electromagnetic flowmeter will generate a magnetic field around the pipeline that is proportional to the fluid flow velocity. The charged particles in the liquid generate an induced potential perpendicular to the magnetic field direction. By measuring the magnitude of this induced potential, the flow velocity and flow rate of the liquid can be obtained.

Ultrasonic flowmeter: measures flow rate using the proportional relationship between ultrasonic propagation speed and fluid flow velocity. By sending a beam of ultrasonic waves through a fluid and receiving the reflected ultrasonic waves at a receiver, measuring the propagation time and reception intensity of the ultrasonic waves, the flow velocity and flow rate of the liquid can be calculated.

Mass flowmeter: measures fluid flow rate according to the law of conservation of mass. The flow rate is determined by measuring the mass flowing through the pipeline per unit time. Typically, a mass sensor is installed on the pipeline to measure the change in fluid mass, and the mass flow rate is calculated by combining the pressure difference and fluid density upstream and downstream.

These liquid flow meters monitor and control fluid flow by measuring different physical quantities such as vortex fluctuations, electromagnetic induction, ultrasonic propagation speed, and mass changes.
