Liaocheng IC card remote transmission vortex flowmeter, refinery vortex flowmeter with good quality

Description :

Liaocheng IC card remote transmission vortex flowmeter, refinery vortex flowmeter with good qualityThe development of vortex flowmeters in China has also attracted attention. In the early 1970s, Chongqing Industrial Automation Instrument Research Institute and Beijing Public Utilities Research Institute invested in the research and development of vortex flowmeters. By the late 1980s, there were about 10 companies in countries such as the United States, Europe, and Japan producing various vortex flowmeter products. According to relevant information, the production of vortex flowmeters in 1987 was close to 40000 units. If a malfunction occurs, the power supply should be checked for correctness and the fluid conditions should be checked for changes. If the malfunction cannot be resolved, please contact Qingdao Heshengzhiyuan Co., Ltd. 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

Liaocheng IC card remote transmission vortex flowmeter, refinery vortex flowmeter with good qualityIt is a stress type vortex flowmeter that measures flow based on the Karman vortex street principle. It has a high signal-to-noise ratio, high sensitivity, and strong vibration resistance. Liaocheng IC card remote transmission vortex flowmeter, refinery vortex flowmeter with good quality signal circuit uses single-chip technology for data processing. The refinery vortex flowmeter encapsulates the CPU unit, storage unit, display unit, communication unit, and other functional modules in the amplification circuit, with RS485 communication function, very stable zero point and accuracy, with diameters ranging from DN25 to DN300. Qingdao Zhiyuan Instrument LUB-2340IC card remote transmission vortex flowmeter is used to measure the volume flow rate and mass flow rate of superheated steam, saturated steam, compressed air, and general gases and liquids.

　　Qingdao Zhiyuan InstrumentLiaocheng IC card remote transmission vortex flowmeter, refinery vortex flowmeter with good qualityIt is an instrument installed on pressure pipelines that requires strict pressure resistance testing before installation, which is an important environment to ensure safety. Article 15 of the Special Equipment Safety Law, which came into effect on January 1, 2014, stipulates that "the manufacturing process of special equipment such as boilers, pressure vessels, and pressure pipeline components, as well as the installation, renovation, and major repairs of boilers, pressure vessels, pressure pipelines, elevators, lifting machinery, passenger ropeways, and large amusement facilities, shall be supervised and inspected by special equipment inspection agencies in accordance with the requirements of safety technical specifications. The protection level of the steam vortex flowmeter for measurement is IP65, and the electrical interface is M20 1.5, ambient temperature: -35 ℃~60 ℃, relative humidity: 5~95%. 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, not in contact with the measured medium. Therefore, the vortex flowmeter has the characteristics of simple structure, good universality, and high stability, which makes the components (especially the vortex generator) highly versatile, and truly achieves the repeatability and accuracy of the sensor without being affected by the replacement of components; Capable of generating strong and stable vortex signals

　　Qingdao Zhiyuan InstrumentIC card remote transmission vortex flowmeterInstallation and usage instructions:

　　1. The installation of IC card meter reading flow meters 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.Jining flowmeterInstall anti vibration seats and add anti vibration pads at both upstream and downstream 2D locations.

　　3. Steam trade settlement flow meters 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 liquid vortex flowmeter 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. Liaocheng IC card remote transmission vortex flowmeter, refinery vortex flowmeter with good quality. The variable diameter method requires a straight pipe section with a length of 15D or more between the variable diameter pipe and the instrument for rectification, making processing and installation inconvenient. In order to be convenient to use, the battery powered local display vortex flowmeter adopts micro power consumption high-tech. It can run continuously for more than one year with lithium battery power supply, saving the procurement and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. on site. The pulse signal output by the flow sensor directly corresponds to the vortex separation frequency, with high cumulative accuracy. However, pulse signals are easily affected by on-site frequency converters, electromagnetic signals, and other sources, resulting in fluctuating flow values and inaccurate readings, which can easily lead to trade disputes between both parties
