Smart Electromagnetic Flowmeter

Description

1. Overview of KNKE Smart Electromagnetic Flowmeter

The KNKE Smart Electromagnetic Flowmeter operates on the principle of Faraday’s Law of Electromagnetic Induction. It combines fluid mechanics and electromagnetics to deliver precise volumetric flow measurements for conductive liquids. When a conductor moves through a magnetic field, it generates an electromotive force. The flowmeter uses this principle by incorporating excitation coils, a magnetic field, and electrodes to detect the fluid flow rate.

This updated version of the LDG series flowmeter features an improved appearance, fast-installation welding-free assembly, and optimized magnetic field distribution, making it more efficient and user-friendly.

2. Structural Features

• Simple and Reliable Design: The instrument has no moving parts, ensuring long operational life and minimal maintenance.
• No Flow Obstruction: The absence of flow obstructions prevents pressure loss and fluid blockages.
• Fast Response and Stability: With no mechanical inertia, the flowmeter responds quickly and maintains excellent stability, making it ideal for automated systems.
• Unaffected by Physical Properties: Measurement accuracy is not influenced by the medium’s temperature, viscosity, density, or pressure.
• Durable Lining and Electrodes: The use of PTFE or rubber lining combined with HC, HB, 316L, Ti, and other electrode materials ensures compatibility with various media.
• Multiple Configurations Available: The flowmeter comes in pipeline and insertion types to meet different application needs.
• Data Protection: Built-in EEPROM securely stores measurement and calculation data, ensuring reliability.
