Selection and installation of factory wastewater flow meters

Factories in most industries produce wastewater, and the main factories that produce large quantities of wastewater are as follows:

1. Chemical plants: The chemical industry involves many reactions and processes, many of which require water for cooling, cleaning, and dilution, which generates large quantities of wastewater.

2. Textile mills: Textile mills require large quantities of water to clean, dye, and treat fibers, which produces a great deal of wastewater containing dyes and chemicals.

3. Paper mills: The paper industry requires large quantities of water to convert wood fibers into paper, which produces a large amount of suspended solids and chemicals in the wastewater.

4. Metal processing plants: Metal cutting, coating, and treating processes generate large quantities of wastewater, which may contain heavy metals and hazardous chemicals.

5. Food processing: Food production requires large quantities of water for washing, steaming, and processing, which generates wastewater containing food residues.

When measuring the flow of these wastewaters, consider using the following types of water flow rate measurement devices:

1. Electromagnetic flowmeter: The mag flow meter is suitable for fluid flow measurement, and can accurately measure the flow of conductive liquids, such as chemical plants produce wastewater containing chemicals. Its measuring principle utilizes the electromagnetic induction that occurs when a liquid passes through a magnetic field to measure flow.

2. Ultrasonic flowmeter: Ultrasonic flow meters are suitable for measuring the flow rate of liquids and gases. The measurement calculates the flow rate by measuring the time it takes for the ultrasonic waves to propagate through the fluid. This type of flow meter is non-invasive and suitable for handling corrosive or hazardous wastewater.

3. Vortex flowmeter: Vortex transmitters are suitable for liquid and gas flow measurements. The flow rate is estimated by measuring the frequency of the vortices generated inside the vortex as the fluid passes through it. It is suitable for environments where high-precision measurements are required.

As an example: One of our local chemical plants produces a large amount of wastewater containing chemical substances and needs to measure the flow rate of the wastewater. Due to the high conductivity of chemical substances, you can choose the electromagnetic flow meter for measurement. Our AUTO brand of electromagnetic flow meters can accurately measure liquid fluids containing chemicals without pressure loss to the fluid, making them suitable for use in wastewater pipelines. Its advantages include:

1. Accuracy: The digital water flow meter can accurately measure the wastewater flow to meet environmental standards and treatment requirements.

2. Adaptability: The electronic flow meter is suitable for measuring a variety of liquids, including wastewater containing solid particles or chemical substances.

3. Stability: The digital flow meters for water sensors are usually located outside the pipeline and will not be in contact with the fluid, so it is not easy to be affected by corrosive media and have a high degree of stability and durability.

4. Easy to maintain: Electromagnetic flowmeter has no moving parts, so it is low maintenance and less prone to failure.

Therefore, for the above chemical plant, the electromagnetic flow meter is a good choice. It contributes to the effective monitoring and management of wastewater treatment processes as it provides accurate, stable, and reliable measurements while adapting to the characteristics of the wastewater.
