Intelligent Digital Display Electromagnetic Flowmeter with PTFE Lining, 316L Electrode, DN100

Electromagnetic flowmeters are flow measurement devices based on Faraday's law of electromagnetic induction, offering advantages including:

1. High Precision Measurement: Electromagnetic flowmeters are unaffected by changes in fluid density, viscosity, temperature, or pressure. Within a certain conductivity range, they provide high measurement accuracy. Their measurement principle is linear, ensuring a definite linear relationship between the measured parameters and the induced electromotive force as described by Faraday's law, further guaranteeing measurement accuracy. The sensor's induced voltage signal has a linear relationship with the average flow velocity, with an error range typically between ±0.5% and ±1%, enabling accurate flow measurement results.

2. Low Pressure Loss: Since there are no obstructions in the measuring tube, electromagnetic flowmeters do not cause additional pressure loss to the fluid. This not only helps reduce system energy consumption but also protects the safe operation of pipelines and equipment. Compared to other flowmeters, they offer significant energy-saving effects, making them particularly suitable for large-diameter water supply pipelines requiring low resistance loss.

3. Wide Rangeability: Electromagnetic flowmeters have a wide rangeability, up to 1:100 or higher, with a flow velocity measurement range of up to 100:1 or even 1000:1. This makes them suitable for various flow measurement needs, accurately measuring both large and small flows.

4. Good Corrosion Resistance: Electromagnetic flowmeters can be equipped with different electrode and lining materials to suit the measurement needs of various media. With appropriate lining material selection, they can measure general corrosive fluids, greatly expanding their application scope and service life. For example, using polytetrafluoroethylene or polyvinylidene fluoride linings allows measurement of various acids, alkalis, salts, and other corrosive media; using wear-resistant rubber linings is particularly suitable for measuring liquid-solid two-phase flows with solid particles, such as abrasive slurries, cement slurries, as well as various fibrous liquids and pulp suspensions.

5. Suitable for Complex Fluids: Electromagnetic flowmeters are particularly suitable for measuring liquid-solid two-phase fluids such as slurries containing solid particles and wastewater. Additionally, they can measure various media, including high-temperature and high-pressure fluids (with certain temperature limitations but still applicable within a range) and viscous slurries, dirty, corrosive, and suspended liquid-solid two-phase flow media.

6. No Mechanical Inertia: Electromagnetic flowmeters respond sensitively and can measure instantaneous pulsating flows with good linearity. This gives them significant advantages in applications requiring rapid response and precise control.

7. Relatively Simple Installation and Maintenance: Electromagnetic flowmeters have relatively low straight pipe requirements, making installation and maintenance relatively simple. The sensors are easy to clean and disinfect, reducing user costs and time, particularly in industries with high hygiene requirements such as food and biopharmaceuticals.

8. Advanced Signal Processing Technology: Electromagnetic flowmeters use advanced microcontroller technology, with digital processing of measurement signals enhancing measurement stability and reliability. This also makes data transmission and processing more convenient and efficient. The converter employs the latest international microcontrollers (MCU) and surface-mount technology (SMT), ensuring reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting.

9. Strong Anti-Interference Capability: Electromagnetic flowmeters can resist external electromagnetic interference and vibration interference, allowing them to be used in various harsh environments while ensuring measurement accuracy. However, despite their strong anti-interference capability, accuracy may still be affected in environments with significant electromagnetic interference, such as near power lines.

10. Diverse Display Methods: Electromagnetic flowmeters can use various display methods, including digital display, analog display, and pulse output, facilitating real-time monitoring and data processing for users.

11. Energy Saving and Environmental Protection: Electromagnetic flowmeters require no consumables and are easy to maintain, offering energy-saving and environmentally friendly characteristics that meet modern industry's requirements for sustainable development and environmental protection.

12. Bidirectional Measurement Capability: Electromagnetic flowmeters are bidirectional measurement systems, equipped with three totalizers that can display forward total, reverse total, and difference total, allowing measurement of both forward and reverse flow.

In summary, electromagnetic flowmeters are widely used in industries such as chemical, petroleum, food, pharmaceuticals, papermaking, environmental protection, and water supply and drainage due to their advantages of high accuracy, no pressure loss, wide range, strong corrosion resistance, broad applicability, sensitive response, simple installation, digital signal processing, strong anti-interference capability, and diverse display methods.
