Huaibei flowmeter special equipment license, general agent for boiler steam flowmeter

Description :

LUB-2340 flowmeter special equipment licenseIt uses the Karman vortex street principle for flow measurement. When a cylindrical object is vertically inserted into the measuring tube, the fluid naturally alternates between regular vortices on both sides of the object, which is called a Karman vortex street At d/D=0.281, the released vortex is stable. D is the diameter of the pipeline. ）The release frequency of the Karman vortex street is related to the flow velocity of the fluid and the width of the column. The boiler steam flowmeter has a simple and sturdy structure, no movable parts, high reliability, and easy maintenance. When measuring gas flow in a vertical pipeline, the sensor can be installed in the vertical pipeline with no restrictions on the flow direction. If the tested gas contains a small amount of liquid, the gas flow should be from bottom to top, and the sensing element should be replaced online - some manufacturers' sensing elements are combined with the vortex generator, which may seem simple in design but brings inconvenience to practical use. Because once the sensing part fails, the medium inside the pipeline needs to be emptied and depressurized before replacing the components, which affects production. A perfect design should separate the two, so that the sensing part can be replaced separately without emptying the medium,Huaibei flowmeter special equipment license, general agent for boiler steam flowmeterVortex street has no mechanical movable parts, small volume, corrosion resistance, stable performance, can directly display the working pressure, temperature, and flow rate of the medium, wide range, and small measurement error. It has been widely used in the production measurement of oil and gas wells and the sales measurement of natural gas. In 1908, Ben Nai pointed out that the periodicity of the wake behind a cylinder is related to the formation and arrangement of vortices. When measuring high-temperature steam, the insulation layer should not exceed one-third of the height of the support.

　　Advantages of Qingdao Zhiyuan Instrument Boiler Steam Flow Meter:

　　1. The detection component does not come into contact with the medium, with stable performance and long service life

　　2. The sensor is installed separately from the vortex generator using a detection probe, and a high-temperature resistant piezoelectric crystal is sealed inside the detection probe, which does not come into contact with the measured medium. Therefore, the flowmeter special equipment license has the characteristics of simple structure, good universality, and high stability.

　　3. Output pulse signals or analog signals proportional to the flow rate, without zero drift, high accuracy, and convenient networking with computers

　　4. The boiler steam flowmeter has a wide measurement range, with a range ratio of up to 1:10

　　In the past thirty years,Special equipment license for flow metersDue to its long-term stability and high precision, it has helped customers make significant progress in productivity. In order to meet the constantly changing market demands, products such as high-temperature, wide range, reduced diameter, and fieldbus communication have been developed accordingly. Recently, Qingdao Hesheng Zhiyuan Automation System Co., Ltd.'s vortex flowmeter has been well applied in steam flow measurement, contributing to customers' energy-saving activities. Our company will continue to develop new products to meet the needs of customers and the market.Huaibei flowmeter special equipment license, general agent for boiler steam flowmeterThe vortex flowmeter is installed in a measuring pipeline with a vertical column, and the fluid alternately generates regular vortices on both sides of the column. This vortex is also known as the Karman vortex flowmeter. Almost at the same time, East ech company successfully developed a thermistor detection vortex flowmeter, which uses a triangular column generator and was later introduced by Japan's OVAL company. The vortex flowmeter is conducive to the Karman vortex principle and has developed rapidly since the 1970s. Nowadays, the proportion of vortex flow sensors used in developed countries such as Japan, Europe and America has increased significantly, and it has been widely applied in various fields. It will dominate the sensor industry in the future. The development of anything cannot be smooth sailing, and the development of vortex flowmeters is the same. After a period of sunny days in the mid to late 1980s, the development of vortex flowmeters slowed down from the early 1990s. In the mid-1980s, they proposed the idea of dry calibration of vortex flowmeters in conjunction with the standardization process of throttling devices, and put forward suggestions at the National Flow Industry Development Planning Conference
