Difference between electromagnetic water meter and electromagnetic flow meter

First of all, electromagnetic flow meter has a simple structure, high measurement stability, no internal obstructions, and no pressure loss.
But its measurement range is relatively narrow, and it is suitable for measuring fluids with stable flow rates. It is widely applicable, and is suitable for fluid measurement in all industry. Its caliber range is wide, available from DN15 to DN3000.
In recent years, the price of electromagnetic flow meter has also been greatly reduced, and it is an economical and practical flow metering product.
Regarding electromagnetic water meters, which are mainly used in the water industry. Because the standards of water meters are relatively strict, they have higher requirements on the accuracy and upper and lower limits of products, so their technical difficulty is much higher than that of electromagnetic flow meters. but he caliber of its normal products is basically within DN300.
The accuracy of the electromagnetic water meter is grade 1 and 2, and the accuracy of the electromagnetic flow meter is ±0.5 (standard), ±0.2 (optional). It is not accurate to say that the accuracy of the water meter is lower than that of the flow meter. The lower limit of the water meter is relatively low. In the case of low flow rate, the electromagnetic flow meter cannot measure according to the principle. At the same time, in the case of large flow fluctuations, the measurement of the electromagnetic flow meter is relatively poor. It can only be said that the two processes overlap, the accuracy of the electromagnetic flow meter is better than that of the electromagnetic water meter. In the lower limit flow, the electromagnetic water meter is better than the electromagnetic flow meter. It is precisely because of the particularity of the water industry that the electromagnetic flow meter cannot complete the measurement of small flow, so there is an electromagnetic water meter.
At present, since the core technology of electromagnetic water meters is in the hands of a few manufacturers, the price of electromagnetic water meters is relatively high.
In addition, the water meter is closely related to the software system, which can analyze the water consumption in real time. It is widely used in the water industry and can perform various functions such as zone measurement and leak detection.
