Usage Guidelines:
Avoid violent impact and chemical corrosion.
Do not throw or collide with the product.
The medium temperature should not exceed 100°C.
Ensure proper installation to prevent leakage or inaccurate readings.
The flowmeter is designed for clean, low-viscosity liquids only; do not use it with abrasive or high-viscosity fluids.
Always connect the device to a stable power source within the specified voltage range (DC3.5-24V).
Avoid exposure to extreme environments, including high humidity and direct sunlight, to ensure long-term durability.
Regularly check and clean the flowmeter to prevent blockages caused by impurities in the medium.
