Putian digital air flow meter, factory price of air flow meter

Description :

In the past thirty years,Digital air flow meterDue 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.Putian digital air flow meter, factory price of air flow meterThe emergence of vortex flowmeters in this situation is not a bad thing, but a concrete manifestation of the twists and turns in the development of things. The emergence of this situation can draw the attention of personnel involved in development, production, design, application, and other aspects. Successfully developing a dual generator and dual detection element stress type vortex flowmeter and first providing customers with dry calibration technical indicators in the installation and use manual; Tokyo Jizhuang Zhushi Company has successfully developed a photoelectric vortex flowmeter, which is processed using a CNC lathe to ensure accuracy in coaxiality and smoothness. With special processing techniques, it overcomes the common problem of the inherent self oscillation frequency of vortex flowmeters affecting the signal. This is the unique technological advantage of KOU Company in producing vortex flowmeters. In the mid to late 1990s, we also saw many successful articles on the application of vortex flowmeters in enterprises. These articles compare the technical characteristics and parameters of orifice flow meters and vortex flow meters from different aspects, and believe that vortex flow meters are a valuable and promising flow instrument with broad development prospects

　　Qingdao Zhiyuan InstrumentDigital air flow meterInstallation and usage instructions:

　　1. The installation of digital anti vibration flowmeter should avoid the influence of strong electrical equipment, high-frequency equipment, strong switching power supply, high temperature, high humidity, and corrosive atmosphere.

　　2. When there is strong vibration in the pipeline, vibration reduction measures should be taken.Laiwu flowmeterInstall anti vibration seats and add anti vibration pads at both upstream and downstream 2D locations.

　　3. The anti vibration vortex flowmeter can be installed horizontally, vertically, and obliquely; The medium must fill the pipeline and have a certain back pressure.

　　4. The process pipeline should be concentric with the flow meter; The inner diameter of the process pipeline should be consistent with the inner diameter of the flow meter, otherwise a contraction tube or expansion tube should be installed.

　　5. The sealing gasket of the vortex flowmeter in the textile factory cannot protrude into the pipeline, and the inner diameter of the sealing gasket can be 1-2mm larger than the inner diameter of the flowmeter.

　　6. If temperature and pressure compensation is required, the pressure tap should be located 3-5D downstream, and the temperature tap should be located 6-8D downstream.

　　7. Putian digital air flow meter, air flow meter factory price. Vortex flow meters should be avoided from being installed on pipelines with strong vibration as much as possible. If installation is necessary, pipeline fastening devices and anti vibration pads must be added at the 2D upstream and downstream locations to enhance the anti vibration effect. Within a certain Reynolds number range, the flow characteristics are not affected by fluid pressure, temperature, viscosity, density, or composition, but only by the shape and size of the vortex generator. The vortex flowmeter is installed in the measuring pipeline with a vertical column, and the fluid alternately generates regular vortices on both sides of the column. This type of vortex is also known as Karman vortex street. The advantage of intelligent vortex street flowmeters is that they have excellent anti vibration performance, no zero drift, and high reliability. According to relevant information, by early 2004, a new situation appeared in the development and production of vortex street flowmeters in China. There are over 200 enterprises with an annual output of over 30000 units

　　In the mid to late 1990s, we also saw many successful articles on the application of vortex flowmeters in enterprises. These articles compare the technical characteristics and parameters of orifice flow meters and vortex flow meters from different aspects, and believe that vortex flow meters are a promising flow instrument with broad development prospects. For a long time, scholars have been observing and studying the regularity of vortex formation, exploring the reasons for the destructive effects of vortex flow meters, and finding methods to prevent such destructive effects. In the mid-20th century, some scholars claimed that the struggle between humans and the harmful effects of vortices had lasted for nearly half a century. With the improvement of product quality, standardization of design, selection, installation, and use, strengthening of pre-sales and after-sales services, and a decrease in on-site failure rates, user satisfaction has increased and confidence has been restored
