With the acceleration of China's industrialization process, environmental pollution problems are becoming increasingly serious, and the call for sustainable development in society is also growing. The concept of harmonious coexistence between humans and nature has been accepted by people, and the governance of various types of pollution is becoming more urgent. Because in the sewage treatment process, it is necessary to measure and control the discharge of sewage, additives, sludge, etc., flow measurement is very important.Industrial wastewater flowmeter manufacturerAmong the numerous flow meter products used for sewage measurement, electromagnetic flow meters have the advantage, both in terms of principle and measurement accuracy, they are good. There are no other components inside the pipeline of the electromagnetic flowmeter, so in addition to measuring the flow rate of conductive fluids, it can also be used to measure the flow rate of non-conductive liquids of various viscosities (with the addition of ionizable substances). Electromagnetic flow meters are often used in the nuclear energy industry.
Industrial wastewater flowmeter manufacturerThe industrial wastewater flowmeter is based on Faraday's law of electromagnetic induction and is used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μ S/cm. It is an inductive instrument for measuring the volumetric flow rate of conductive media. In addition to measuring the volumetric flow rate of general conductive liquids, it can also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp.
Precautions for using industrial wastewater flow meters
1. The accuracy level and function of the instrument are selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, higher accuracy levels such as 1.0, 0.5, or higher should be selected; For process control applications, choose different accuracy levels according to control requirements; In some cases where only the process flow rate needs to be detected without precise control and measurement, a slightly lower accuracy level, such as 1.5, 2.5, or even 4.0, can be selected. In this case, a low-cost plug-in electromagnetic flowmeter can be used.
2. When measuring medium flow rate, instrument range, and caliber, the full flow rate of an electromagnetic flowmeter can be selected within the range of 0.5-12m/s for measuring medium flow rate, which is relatively wide. The selection of instrument specifications (caliber) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument port diameter needs to be reduced to increase the flow rate inside the pipeline and obtain satisfactory measurement results.
3. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.
4. It should be installed in a dry and ventilated place as much as possible, avoiding direct sunlight and rain. The ambient temperature should be between -20 and+60 ℃, and the relative humidity should be less than 85%.
5. There should be ample space around the flowmeter for easy detection and maintenance.
