Description :

Qingdao HeshengDigital low flow rate flowmeter, steam remote meter reading flowmeter, high-precision vortex flowmeterFeatures: 1. Digital vortex flowmeter: The digital vortex flowmeter is equipped with DSP signal processing circuit and anti vibration algorithm, and is equipped with mature piezoelectric crystal sensors. After long-term on-site testing and operation, its performance is reliable. Even under complex operating conditions, digital vortex flowmeters can effectively identify the vortex signals generated by the body and achieve accurate and stable operation. 2. Anti vibration performance: Starting from the conductive part of the sensor, vibration is avoided. The electric plate part uses Fourier transform and seismic algorithm to effectively identify normal vortex flow signals and filter the identified signals. Large pipeline vibrations and abnormal flow conditions can achieve anti vibration performance and accurate measurement. 3. Spectrum analysis: Possess DSP spectrum signal analysis capability, able to analyze the fluid signal generated in the digital vortex flowmeter, and automatically select the operating condition based on dynamic data and self provided database comparison. 4. The flow output signal of the ultra wide range control sensor probe is accurately captured by the DSP to ensure the vortex signal in the low flow area, thereby significantly improving the stability of the measurement and expanding the range ratio of the flowmeter, which can reach up to 1:80. 5. High precision measuring machine tool precision machining of vortex street shell and vortex generator, combined with digital vortex street board, gas measurement accuracy can reach up to 0.75%. In 1908, Ben Nair 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 support height, and the regulating valve should not be installed upstream of the vortex flowmeter as much as possible, but should be installed at 10D downstream of the vortex flowmeter

　　Digital low flow flowmeter protection level: IP65, electrical interface: M20 × 1.5, ambient temperature: -35 ℃~60 ℃, relative humidity: 5~95%. By the late 1980s, there were about 10 companies in the United States, Europe, Japan and other countries producing various vortex flowmeter products. According to relevant information, the world's production of vortex flowmeters was close to 40000 units in 1987

　　The special flange for digital anti vibration vortex flowmeter cannot be welded with a sensor when welding to the straight pipe section. During installation, the flow direction indicator of the sensor should be consistent with the fluid flow direction inside the pipeline.

　　Before installing the sensor, a sealing ring must be placed in the flange groove. The positions of pressure and temperature measurement points are as follows: the pressure measurement point is located 3-5 DN downstream of the sensor, and the temperature measurement point is located 5-8 DN downstream.

　　When measuring high-temperature media with a boiler feedwater vortex flowmeter, do not wrap the sensor connecting rod around it with insulation material.

　　The shielded cable connecting the sensor should be routed as far away as possible from strong electromagnetic fields. It is not allowed to be laid together with high-voltage cables. Shielded cables should be shortened as much as possible and should not be coiled to reduce distributed inductance. Large lengths should not exceed 100 meters.

　　Before installing the sensor on the flow meter in Liaocheng, the pipeline must be cleaned. Remove impurities from the tube to avoid clogging the sensor after flow. The pipeline for measuring liquids must be filled with the measured liquid to prevent bubbles.

　　The emergence of digital low flow rate flow meters, steam remote meter reading flow meters, and high-precision vortex street flow meters has also led to the evolution of the product landscape. Some enterprises with weak technical strength, insufficient production equipment and testing conditions, and difficulty in ensuring product quality and providing services to users have gradually been eliminated by the market. In 1908, Ben Nai pointed out that the periodicity of the wake behind the 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 support height. The installation of flow meters on horizontal pipelines: When measuring gas flow, if the measured gas contains a small amount of liquid, the flow meter should be installed at a higher position in the pipeline. When measuring liquids, if the measured liquid contains a small amount of gas, the flowmeter should be installed at a lower point in the pipeline
