Abstract: The application information of intelligent
electromagnetic flowmeter in water plants is provided by excellent flowmeter and flowmeter manufacturers. Since the intelligent electromagnetic flowmeter must be used continuously online, it is almost impossible to dismantle and transport it to the National Metrology and Testing Center for verification. Therefore, it is necessary to verify the accuracy of the large-diameter electromagnetic flowmeter used in the field. The precision of electromagnetic flowmeter. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application article details of intelligent electromagnetic flowmeters in water plants. Since the intelligent electromagnetic flowmeter must be used continuously online, it is almost impossible to dismantle and transport it to the National Metrology and Testing Center for verification. Therefore, it is necessary to verify the accuracy of the large-diameter electromagnetic flowmeter used in the field. The accuracy verification of electromagnetic flowmeter is also very useful for the management of electromagnetic flowmeter, to ensure its accuracy and reliability, to accumulate original comparison data, and to do future verification and verification. The accuracy verification of the electromagnetic flowmeter can use the volume of the clean water tank and the electromagnetic flowmeter to verify the equipment. The verification of the measurement accuracy of the electromagnetic flowmeter of the factory water of the water plant adopts the clear water tank volume method, which is one of the methods often used by the water supply enterprises. Under the condition that the geometric dimensions of the clean water pool are accurately measured and the operating errors are reduced, a high comparison reference can be obtained. The principle of the clear water pool volume method is: use a high-precision steel ruler to measure the actual space plane size of the clear water pool and the suction well, and accurately calculate the actual plane area of the clear water pool and the suction well. First, adjust the water level of the clear water pool to a higher water level and close all water outlet valves. When the water level of the clean water pool is stable, use the clean water pool level transmitter again and use a high-precision steel ruler to manually and accurately measure the water level of the clean water pool and the suction well, record the water level of the clean water pool and the water suction well again, and record the electromagnetic flowmeter to be verified. . Finally, the water level height difference ⊿h between the clear water pool and the suction well is calculated, so as to calculate the actual water volume of the clear water pool and the suction well. The actual water volume is equal to the height difference ⊿h multiplied by the plane area and the corrected water volume. After the water level of the clean water pool is stable, use the clean water pool level transmitter and manually measure the water level of the clean water pool and the suction well with a high-precision steel ruler. In order to correct the error caused by the leakage of valves such as clear water pool, measure the water level of clear water pool and suction well again after a certain interval, and calculate the amount of water leakage per unit time in order to correct the water metering and reduce errors. The purpose of recording the cumulative flow of the electromagnetic flowmeter to be verified, and manually measuring the liquid level of the clean water pool and suction well is to verify the accuracy of the liquid level transmitter. Then turn on the water pump, open the water outlet valve, and after a certain period of time, close the water outlet valve to stop the pump. The above is the whole content of this article.
