1. What are the reasons for unstable output of intelligent electromagnetic flowmeter?

The reasons for unstable output of intelligent electromagnetic flowmeter may include the following: improper selection of lining and electrode materials: the medium measured by the user is weakly acidic sewage discharged from the chemical plant, but the electromagnetic flowmeter used is only equipped with ordinary rubber lining and 316L electrode. Long term contact with acidic media can cause corrosion, expansion, or peeling of rubber lining, while 316L electrodes may undergo oxidation or chemical erosion in weakly acidic environments, resulting in signal interruption or fluctuation. This type of working condition requires the use of corrosion-resistant lining (such as polytetrafluoroethylene) and corrosion-resistant electrodes such as Hastelloy alloy. Missing selection information leads to configuration errors: Distributors did not fully understand the users on-site working conditions during procurement and only produced equipment according to conventional parameters. The lining and electrode materials were not customized according to the characteristics of the medium (such as acidity, alkalinity, temperature, pressure), resulting in rapid failure of the equipment in harsh environments. This reflects the oversight in the confirmation of working conditions during the selection process. Mismatch between medium characteristics and equipment: Weakly acidic wastewater may contain solid particles or impurities, and long-term flushing can accelerate lining wear. If the conductivity of the medium is unstable (such as concentration changes), it will also affect the accuracy of electromagnetic induction signals, leading to output fluc

tuations. In addition, excessive temperature of the medium may cause aging and deformation of the rubber lining, further interfering with the measurement. Installation or environmental interference factors: Although not explicitly mentioned in the case, the following situations may also cause unstable output: improper installation location, such as near strong magnetic field equipment (motors, frequency converters) or vibration sources, causing electromagnetic interference or mechanical vibration. Poor grounding: The electromagnetic flowmeter needs to be reliably grounded to eliminate static electricity and stray currents, otherwise the signal may be affected by noise and impulse. Pipeline not filled with medium: If there is gas or cavity inside the measuring pipeline, it will cause distortion of the flow signal. Equipment aging or insufficient maintenance: After long-term operation, the lining may bulge due to medium infiltration, and the electrode surface may scale or be contaminated, all of which will reduce the sensitivity of signal detection. Regularly checking the integrity of the lining and cleaning the electrode surface are key to maintaining stable output. Solution and preventive measures: Material upgrade: For acidic working conditions, PTFE lining and Hastelloy C-276 electrode are selected to enhance corrosion resistance. Strict selection process: Sales personnel and distributors are required to obtain parameters such as medium composition, temperature, pressure, flow rate, etc. from the users site to ensure that the equipment configuration matches the working conditions. Regular maintenance: It is recommended that users dismantle and inspect the equipment every 6-12 months, focusing on checking the wear of th
