1. Rosemount Electromagnetic Flow Meter Setting
The setting of Rosemount electromagnetic flow meters (taking 8712E/8712H as an example) mainly revolves around unit, range configuration, and installation calibration. The core operation is completed through panel buttons. 1. Common setting steps • Setting measurement units: Press the "UNITS" key to enter the menu, use the "SHIFT" or "INCR" keys to select the desired unit (such as cubic meter/hour), press "ENTER" to save and exit. • Set the range of Xiaotong: Press the "ANALOG OUTPUT RANGE" key to enter the menu, use "SHIFT" to move the cursor to the upper range value (URV), adjust the value through "INCR", and press "ENTER" to confirm
2. Key functions • SHIFT: Move the cursor to the parameter position that needs to be modified. INCR: Increase or decrease the highlighted values. • ENTER: Save current settings and exit
3. Installation and calibration requirements • Installation position: Ensure that the front and rear straight pipe sections (usually 10D in the front and 5D in the back, with D being the pipe diameter) are kept away from disturbance sources such as valves and pumps to avoid vibration and impact. Grounding and connection: Strictly follow the manual requirements for grounding, ensure that the electrode and pipeline potentials are consistent, and the cable length meets the specifications. Wheel Sparrow Calibration and Debugging: Introduce a known flow rate fluid, compare the displayed value with the standard value, and adjust the calibration coefficient through the menu. • Maintenance: Regularly clean the electrodes, check the sealing and cable joints, and perform periodic calibration.
2. How to adjust the base number of electromagn
The adjustment of the base number of electromagnetic flowmeter should strictly follow the static liquid conditions and standard procedures, and the calibration process should be shielded from external interference.
.1. Preparation stage: Check the environment and equipment to ensure that the sensor is fully installed in the pipe and there are no bubbles. Close the upstream and downstream valves to make the medium grip completely stationary.
. Check if the cable connection is secure and eliminate the possibility of physical damage or looseness. The surrounding area should be kept away from strong magnetic fields and vibration sources to avoid signal interference.2. Operation process: Step by step calibration 1 Enter the adjustment interface: After powering on and waiting for the display to stabilize, enter the menu settings interface through the panel buttons (often requiring long pressing of specific keys or combination keys), with slight differences in operation paths for different brands. two Perform zero calibration: Select the "zero adjustment" function, confirm that the medium is stationary, and start automatic calibration. At this time, the instrument will collect the air traffic control signal value and set it as the zero point reference. During the process, pipeline vibration or external electromagnetic interference is strictly prohibited. three Verification and storage: Observe whether the zero point value displayed on the vertical screen of the screen is within the normal fluctuation range marked by the manufacturer (usually within ± 0.5%), confirm that it is correct, and save the parameters.
III. Exception handling: In case of calibration failure, if there is
