1. The difference between turbine flowmeter and vortex flowmeter
Turbine flowmeter and vortex flowmeter have significant differences in design principles, application scope, and characteristics, as follows: Design principle Turbine flowmeter: belongs to velocity flowmeter, focusing on measuring liquids. The principle is to use the relationship between the rotational angular velocity of the impeller placed in the liquid and the liquid flow velocity, and calculate the liquid flow rate by measuring the impeller speed. Vortex flowmeter: designed and manufactured based on the Karman vortex principle, using fluid oscillation principle to measure flow rate. When a fluid passes through a vortex sealed flow transmitter in a pipeline, two columns of vortices proportional to the flow velocity will alternate up and down behind the triangular vortex generator. The frequency of vortex release is related to the average velocity of the fluid and the characteristics of the vortex generator. Application scope: Turbine flowmeter is widely used for measuring objects such as petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas, and low-temperature flow sensors. Vortex flowmeter: mainly used for flow measurement of industrial pipeline medium fluids, suitable for various media such as gas, liquid, vapor, etc. Characteristics of turbine flowmeter: simple structure, few processed parts, light weight, easy maintenance. Large circulation capacity, with a large amount of flow that can be passed through with the same caliber. Can adapt to high parameter environments such as high temperature, high pressure, and low temperature. Vortex flowmeter: small pressure loss, large range, high accuracy. When measuring
2. How to issue a supervision certificate for special equipment vortex flowmeter?
To issue a supervision and inspection certificate for special equipment vortex flowmeter, a special equipment production license (TS certification) must be obtained first. The product manufacturing process is supervised and inspected by the supervision and inspection agency, and after passing the inspection, the supervision and inspection agency issues the certificate.. The following is a specific explanation: The Special Equipment Production License (TS certification) is a prerequisite. According to the Special Equipment Safety Law of the Peoples Republic of China, in the field of special equipment, if manufacturing, using, and testing units cannot obtain the Special Equipment Production License (TS certification) within the prescribed period, the state will not allow them to enter the field of special equipment related economic activities. For vortex flowmeter manufacturers, only by obtaining TS certification can they be allowed to engage in special equipment production activities for flowmeters (casings). For example, Hesheng Measurement and Control has obtained TS certification with its own technological advantages and strict production standards, becoming one of the few approved flowmeter manufacturers in Shandong Province. TS certification is a recognition of a companys professional qualifications and a powerful guarantee for product quality, laying the
