What are the grounding standards for LGF electromagnetic flowmeter sensors?

Electromagnetic flowmeter sensor grounding is crucial for measurement accuracy and equipment safety. The LGF series electromagnetic flowmeter grounding standards include several key aspects:

• Protective grounding: Sensor housing must be reliably grounded with resistance less than 10Ω, using dedicated grounding wire to grounding electrode
• Functional grounding: Establish electrical connection with measured medium through grounding rings or electrodes to ensure complete measurement circuit
• Shield grounding: Signal cable shield should be grounded at single point to prevent ground loop interference
• Equipotential grounding: Install grounding rings when pipeline is non-conductive to ensure sensor-medium equipotential

For radar flowmeter HZ-KSLF and RTU terminals EC32/EC60, proper lightning protection grounding is equally important. TN-S power supply system is recommended with grounding wire cross-section ≥4mm². Grounding points should be away from high-power equipment to ensure stable operation of the entire flow measurement system.
