What issues should be noted when installing a prepaid vortex flowmeter for heating? When installing prepaid vortex street and shed flow meters for heating, attention should be paid to three aspects: external environment, installation pipelines, and installation steps. Specific precautions are as follows:

First, the external environment should avoid harsh environments: the installation location should be far away from thermal radiation sources, areas with drastic temperature changes, and places containing corrosive gases, while avoiding environments with mechanical vibration, electrical noise, or high-frequency noise interference. Priority for indoor installation: If it must be installed outdoors, moisture-proof and sun protection measures should be taken, such as installing protective covers or selecting installation points that provide shade and shelter from the sun and rain, to prevent equipment performance degradation or damage due to environmental factors.

2. Pipeline Installation Specification: Straight pipe section requirements: Adequate length of straight pipe sections should be reserved upstream and downstream of the flowmeter to ensure stable fluid flow and reduce the impact of eddy currents on measurement accuracy.

. The specific length needs to be determined based on the diameter of the pipeline and the model of the flow meter. Vibration control: Prioritize installation locations with vibration acceleration less than 20m/s2. If the pipeline vibration is too strong, reinforcement support structures need to be installed on the pipeline to reduce the possibility of vibration transmission to the flowmeter. Gas liquid separation installation: Gas measurement: When the measured gas contains a small amount of liquid, the flowmeter should be installed at a higher position in the pipeline, using gravity to naturally separate the liquid and avoid liquid entering the flow meter and affecting the measurement. Liquid measurement: When the measured liquid contains a small amount of gas, the flowmeter should be installed at a lower position in the pipeline to ensure that the gas floats up and is discharged, and to prevent gas interference with the measurement results.

III. Key points of installation steps to prevent high temperature and impact: During the installation process, it is necessary to avoid direct contact of the sensor with a high temperature source or mechanical impact, to prevent damage to internal components or performance drift.

. Flow direction matching: Ensure that the flow direction markings on the sensor are consistent with the actual flow direction of the fluid, otherwise it may result in measurement data errors or even damage to the equipment. Standardized operating procedure: Hole positioning: Accurately open the hole on the pipeline according to the requirements of the flowmeter hole size, avoiding the influence of hole diameter deviation on installation sealing. Preliminary positioning: Place the entire set of instruments connected to the flange into the perforated pipeline, spot weld the two flanges to ensure that the axis of the flowmeter coincides with the centerline of the pipeline. Welding and Cleaning: After removing the sensor and completing the flange welding, it is necessary to empty the residue in the pipeline and clean the welding slag to prevent impurities from entering the flow meter. Final installation: Install the sensor into the middle of the flange and evenly fasten it w
