Industrial Sewage Flow Meter Classification Guide 

     In industrial wastewater treatment, choosing the appropriate flowmeter is crucial for precise monitoring and control of wastewater flow. Here is a classification guide for industrial wastewater flowmeters and a detailed analysis of how to select the right solution:

I. Classification of Industrial Wastewater Flowmeters

     Measurement principle: Utilizing Faraday's law of electromagnetic induction, the flow rate is determined by measuring the electromagnetic induction generated when the liquid passes through a conductive pipeline.

Advantages: Not affected by changes in fluid density, viscosity, temperature and pressure, high measurement accuracy, good stability, no maintenance required for long-term use, suitable for large flow rates and conductive liquids.

Disadvantages: Cannot measure non-conductive liquids, strict installation requirements, and specific requirements for pipeline materials and dimensions.

Ultrasonic Flowmeter

Measurement principle: Measuring the difference in the propagation speed of ultrasonic waves in the liquid to determine the flow rate.

Advantages: Non-intrusive to the fluid, no pressure loss and no risk of contamination, suitable for different types of liquids, high measurement accuracy, suitable for various pipe diameters and flow ranges.

Disadvantages: Requires the fluid to contain sufficient gas or bubbles as the medium for ultrasonic wave propagation. 

Measurement principle: The flow rate is measured by the alternating vortices formed when the liquid flows past the obstruction (turbine).

Advantages: Simple structure, high stability, suitable for large flow measurements, unaffected by changes in fluid density, viscosity, temperature and pressure, and can adapt to high-temperature, high-pressure and corrosive media.

Disadvantages: Less accurate for low flow rates and low flow volumes.

Magnetic turbine flowmeter

Measurement principle: Utilizing the rotating magnetic field generated by the rotation of the turbine blades when the fluid flows past the turbine to measure the flow rate.

Advantages: Simple structure, high stability, suitable for large flow measurements.

Disadvantages: Not suitable for measurements with too many impurities during operation, as it may cause the turbine to get stuck and result in inaccurate measurement or even damage to the turbine.

II. How to Choose a Better Solution

    Fluid characteristics

Fluid type: Consider the viscosity, presence of solid particles, and chemical properties of the wastewater. Different flowmeters have different requirements for fluid characteristics. For example, electromagnetic flowmeters are suitable for conductive liquids, while ultrasonic flowmeters have certain requirements for the content of gases or bubbles in the fluid.

Temperature and pressure: The temperature and pressure range of the fluid also affects the selection of the flowmeter. It is necessary to choose a flowmeter that can operate stably within the expected temperature and pressure range.

Flow range

Determine the small and large flow ranges that need to be measured. Different types of flowmeters have different applicability within the measurement range. Choose the appropriate type of flowmeter based on the actual flow changes.

Accuracy requirements

Select the appropriate flowmeter based on the accuracy requirements of the wastewater treatment process. High-precision flowmeters are usually more expensive, but they are very important in situations requiring precise control and monitoring. Environmental conditions

Consider the environmental conditions where the flowmeter will be installed, such as whether it needs to be resistant to corrosion, explosion-proof, withstand high temperatures or low temperatures, etc. Select a flowmeter that can adapt to these environmental conditions.

Cost-effectiveness

Comprehensively consider the purchase cost, installation cost, operation cost, and long-term maintenance cost of the equipment. Choose a flowmeter solution with cost-effectiveness.

Reliability and Durability

The reliability and durability of the flowmeter directly affect the stability of the equipment operation and its lifespan. Select a product with a good brand reputation and proven performance.

Existing Infrastructure and System Integration

Consider the existing pipeline layout, control system, and automation requirements. Ensure that the new flowmeter can integrate well with the existing system to avoid unnecessary renovations and additional costs.
