1. WTG-DC series intelligent electromagnetic flowmeter user manual: [1]
The core content of the WTG-DC series intelligent electromagnetic flowmeter user manual is as follows:
1. Product Overview WTG-DC series intelligent electromagnetic flowmeter is a high-precision flow measurement instrument based on Faradays law of electromagnetic induction, suitable for measuring the volume flow of conductive liquids (such as water, acid-base solutions, slurries, etc.). The product has the characteristics of intelligence, high reliability, and strong anti-interference ability, and is widely used in industries such as chemical engineering, metallurgy, water treatment, and food.
2. Installation Requirements Environmental Conditions: The installation location should be far away from strong magnetic fields and vibration sources, avoiding direct sunlight or direct rain. The ambient temperature should be between -20 ℃ and+60 ℃.
. Pipeline requirements: The flowmeter should be installed horizontally or vertically (when installed vertically, the fluid direction should be from bottom to top), ensuring that the pipeline is filled with liquid and free of bubbles. Before installation, it is necessary to clean the welding slag and debris inside the pipeline to avoid damaging the sensor lining. Grounding requirements: The flowmeter casing and monitoring sensor must be reliably grounded, with a grounding resistance of less than 10 Ω to reduce the impact of electromagnetic interference on measurement accuracy. 3. Operation Method: Wiring Steps: Open the flowmeter junction box and connect the power line (AC/DC 24V or 220V), signal line (4-20mA output), and grounding wire according to the markings. After the wiring is comple
4. Maintenance and Regular Inspection: Check the flowmeter wiring for looseness and the sensor lining for wear every 3 months, and promptly address any issues found.
. Cleaning and maintenance of Qie: If the fluid contains impurities, it is necessary to regularly clean the inlet filter of the flowmeter to avoid blockage and affect measurement accuracy. Calibration cycle: It is recommended to conduct on-site calibration every 12 months to ensure measurement accuracy. Calibration needs to be completed by professionals using standard flow devices.5. Common faults and solutions Fault 1: Flow display is zero or fluctuates greatly Reason: Pipeline is not filled with liquid, sensor electrode contamination, poor grounding.
. Solution: Check if the pipeline is filled with liquid, clean the sensor electrode, re ground and check the grounding resistance. Fault 2: Unstable output signal. Reason: Signal line interference, power supply voltage fluctuations, and incorrect flow meter parameter settings. Solution: Check if th
