Why Use Magnetic Flow Meter to Measure Wastewater?

The electromagnetic water flow meter employs advanced excitation technology, allowing it to quickly establish a magnetic field, reduce the time needed for a stable field to form, and extend the steady measurement period. This technology effectively filters stray signals, increases signal acquisition strength, and ensures more stable measurements. It overcomes common limitations of traditional open channel and ultrasonic flowmeters, enhancing the accuracy and precision of wastewater measurements. Additionally, it is suitable for measuring liquid-solid two-phase flows, high-viscosity liquids, and special liquids such as salts, strong acids, and bases, making it highly versatile.

Advantages of using an magnetic flow meter for wastewater flow measurement:

No Obstructive Components

The magnetic flow meter has no moving mechanical parts and no obstructive components within the measuring tube, allowing fluids to pass through unobstructed. This design prevents wear and clogging caused by solid particles or impurities in the fluid, making it ideal for wastewater containing suspended solids and particles.

High Precision and Reliability

It provides high-precision measurements, with typical accuracy within ±0.2% to ±0.5%. Without mechanical parts, the flowmeter is less prone to drift over long-term use, offering high reliability and low maintenance costs.

Strong Corrosion Resistance

The flowmeter’s lining materials (such as PTFE, hard rubber, polyurethane) and electrode materials (like SS316L, Hastelloy B, Hastelloy C, titanium, and platinum) are highly resistant to corrosion, effectively withstanding various chemical components in wastewater, making it suitable for harsh wastewater environments.

Wide Rangeability

The electromagnetic water flow meter boasts an extremely wide rangeability, with measurement ratios reaching up to 100:1 and, in some cases, as high as 1000:1. This enables it to adapt to varying flow conditions, meeting the flow measurement needs at different stages of wastewater treatment.

Adaptability to Wastewater Treatment Processes

Wastewater treatment processes often involve bubbles, solid particles, and suspended materials, which can impact the accuracy and lifespan of traditional flowmeters. The electromagnetic water flow meter, due to its working principle, is unaffected by these factors and provides stable, accurate measurements.

Easy Maintenance

With a simple structure, the magnetic flow meter is easy to maintain. Since it has no mechanical wear parts, routine maintenance typically involves only periodic inspection and cleaning of the sensor electrodes, resulting in low maintenance costs.
