Jin He briefly describes the ten requirements for the installation of intelligent vortex flowmeters

Abstract: Jin He briefly describes the ten major requirements for the installation of intelligent vortex flowmeters. The information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Abstract: Vortex flowmeters can be widely used in large, medium and small pipelines for water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, as well as the measurement and flow of compressed air, saturated and superheated steam, natural gas and various media. Can be used as flow transmission. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is Jinhe's brief description of the ten requirements for the installation of smart vortex flowmeters. Vortex flowmeter can be widely used in large, medium and small pipeline water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, as well as the flow measurement of compressed air, saturated and superheated steam, natural gas and various media. The flow transmitter is used in the automatic control system, and the EEPROM is used to protect the accumulated flow from power failure, and the protection time is more than 10 years. During the installation process, many people responded that there will always be some problems. In fact, this involves many aspects of knowledge. This article lists the information for some installation requirements for your reference only. Vortex flowmeter can be widely used in large, medium and small pipeline water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, as well as the flow measurement of compressed air, saturated and superheated steam, natural gas and various media. The flow transmitter is used in the automatic control system, and the EEPROM is used to protect the accumulated flow from power failure, and the protection time is more than 10 years. The main points to pay attention to in the installation of vortex flowmeter: 1. Reasonably choose the installation site and environment to avoid strong power equipment, high frequency equipment, strong power switch equipment; avoid the influence of high temperature heat sources and radiation sources, avoid strong vibration places and strong corrosion Environment, etc., at the same time to consider the ease of installation and maintenance. 2. There must be enough straight pipe sections upstream and downstream if there are two 90s on the same plane upstream of the sensor installation point. Elbow, then: upstream straight pipe section≥25D, downstream straight pipe section≥5D if there are two 90s on different planes upstream of the sensor mounting point. Elbow, then: upstream straight pipe section≥40D, downstream straight pipe section≥The 5D regulating valve should be installed outside the 5D downstream of the sensor. If it must be installed upstream of the sensor, the upstream straight pipe section of the sensor should not be less than 50D, and the downstream should not be less than 5D. 3. The piping upstream and downstream of the installation point should be concentric with the sensor, and the coaxial deviation should not be less than 0.5DN4. The pipeline should take vibration reduction measures to avoid installing the sensor on the pipeline with strong vibration, especially lateral vibration. If the installation is unavoidable, vibration reduction measures must be taken, and pipe fastening devices and anti-vibration pads should be installed at the upstream and downstream 2D ​​of the sensor. 5. Installation on horizontal pipes is the most common installation method for flow sensors. When measuring gas flow, if the measured gas contains a small amount of liquid, the sensor should be installed at a higher part of the pipeline. When measuring liquid flow, if the measured liquid contains a small amount of gas, the sensor should be installed at the lower part of the pipeline. 6. When the sensor is installed in the vertical pipeline to measure the gas flow, the sensor can be installed on the vertical pipeline, and the flow direction is not limited. If the measured gas contains a small amount of liquid, the gas flow should be from bottom to top. When measuring liquid flow, the flow direction should be from bottom to top: this will not add extra liquid weight to the probe. 7. The sensor is installed on the side of the horizontal pipeline. No matter what kind of fluid is measured, the sensor can be installed on the horizontal pipeline, especially for measuring superheated steam, saturated steam and low temperature liquid. Amplifiers have less effect. 8. In general, this installation method is not recommended when the sensor is installed upside down in a horizontal pipe. This installation method is not suitable for measuring general gas and superheated steam. It can be used to measure saturated steam, and it is suitable for measuring high temperature liquid or when the pipeline needs to be cleaned frequently. 9. When the sensor is installed on a pipeline with an insulation layer to measure high-temperature steam, the insulation layer should not exceed one-third of the height of the bracket at most. 10. The selection of pressure measuring point and temperature measuring point is based on the needs of measurement. When pressure and temperature need to be measured near the sensor, the pressure measuring point should be at 3-5D downstream of the sensor, and the temperature measuring point should be at 6-8D downstream of the sensor. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
