1. Instrument wiring of plug-in electromagnetic flowmeter

Connection method of integrated intelligent electromagnetic flowmeter The converter core of the integrated electromagnetic flowmeter is installed in an aluminum alloy box coated with epoxy paint on the surface, and the converter can be fixed on the sensor. All circuit boards of the converter adopt surface mount technology, and each board is equipped with electrostatic protection. Therefore, if the user does not have on-site maintenance capabilities, it is not allowed for the user to disassemble the converter on site.

(1) The connection cable from the sensor to the converter adopts the special shielded cable provided by our company, and the power line should use RVV2X0.15/16 cable. The grounding of both the sensor and the converter should be well grounded.

(2) The power supply for the integrated intelligent mining electromagnetic flowmeter and split type converter is configured according to user needs. If the user needs to use a DC24V power supply, the terminal next to the 220V power supply wiring in the diagram will be changed to DC24V at the factory.

(3) If the user needs frequency output, alarm output, or connection to a microcomputer when placing an order, they can connect them to the corresponding terminals indicated in the diagram.

(4) The housing of the sensor must be well grounded.

method of the product and common troubleshooting solutions. Zaoqiao: Product Function Overview Changhui CF-LK Intelligent Flow Calculation Controller is a device used for flow measurement and calculation control. It supports multiple signal inputs (such as pulse, 4-20mA current, etc.) and can achieve functions such as flow accumulation, instantaneous flow display, alarm output, etc. The equipment adopts high-precision algorithms and is suitable for liquid and gas flow measurement scenarios in industrial pipelines. Figure 1: Appearance and usage of Changhui CF-LK controller. Wiring steps: Power supply: Use DC24V or AC220V power supply (choose according to the model), ensure that the wiring terminals are tightened. Signal input: Connect the output signal line of flow sensors (such as vortex street and electromagnetic flow meters) to the corresponding terminal. Output configuration: Connect alarm relays or 4-20mA output to PLC/DCS system according to requirements. Parameter settings can be accessed through the panel buttons to enter the menu, and the following parameters can be set: Range: Enter the maximum/minimum flow value according to the sensor specifications. Small signal cutoff: Avoid measurement interference at low flow rates (recommended to set to 1% -2% of full range). Accumulation method: Select total accumulation or batch control mode. Figure 2: Typical wiring diagram Common fault solutions Fault phenomenon 1: Large fluctuation of display value Possible reasons: Signal line interference, unstable sensor installation. Solution: Check the grounding of the shielded wire and re fix the sensor. Fault phenomenon 2: Inaccurate cumulative value Possible reasons: incorrect range setting, uncalibrated pulse equivalent. S
