The following are the details of the article on the common factors of unqualified electromagnetic flowmeter installation. What are the common factors for unqualified electromagnetic flowmeter installation? How to improve the qualification rate of electromagnetic water meter and electromagnetic flowmeter? Electromagnetic flowmeter is a speedometer that measures the volume flow of conductive medium, and electromagnetic water meter is an instrument specially designed for the water industry, which can meet the needs of urban water supply and ensure the accuracy of water bill calculation. Next, we will compare the differences between them from several aspects. In the past ten years, electromagnetic flowmeters have been widely used in petrochemical and other fields. Due to the large amount of raw materials and intermediate materials on the production site, it is necessary to control and measure the finished liquid medium, which is inseparable from the stable operation and accurate measurement of the electromagnetic flowmeter. The normal operation of the electromagnetic flowmeter sensor needs to be ensured by early reasonable and standardized installation. Negligence in some aspects of the installation process will result in large measurement errors, unstable data and other negative effects, resulting in economic losses and even quality and safety accidents. First of all, on-site investigation In crude oil measurement, the use of electromagnetic flowmeters is gradually increasing, but there are still many installation failures in the process of equipment installation. Reason analysis of common factors for unqualified electromagnetic flowmeter installation: 1. When the sensor installation flange is connected to the pipe flange, the sensor has a different axis, which leads to stress deformation. When the sensor of the electromagnetic flowmeter is deformed by external force, the force on the tube wall will change due to the deformation of the tube when the measured medium flows through the sensor tube, resulting in the phase difference change of the vibration tube detection coil being disproportionate to the mass flow rate, resulting in measurement error increase. 2. The installation mode of the sensor does not match the properties of the measured medium. If the installation method is incorrect, the measured medium will not fill the sensor measurement pipeline, resulting in uneven stress on the inner wall of the pipeline and inaccurate detection coil signals at both ends of the vibrating tube, resulting in a large deviation of the measured value. 3. The installation position is too close to equipment such as large motors or transformers, causing interference. If the sensor is installed too close to the transformer, it will be susceptible to electromagnetic interference, which will make the detection coil signals at both ends of the vibrating tube abnormal, resulting in excessive deviation of the measured value. If the sensor is too close to the motor, it is easily affected by mechanical vibration, resulting in abnormal torsional vibration of the vibrating tube in the sensor, increasing the measurement error. Standardized installation of electromagnetic flowmeter can effectively ensure long-term stable operation of the equipment, and it is also relatively beneficial to the life of the flowmeter.
