Electromagnetic flowmeter
Thread Content
Many of the water pipes in our factory use electromagnetic flowmeters; why can’t orifice flowmeters be used instead?
Agree with what was said above. Moreover, the maintenance requirements are low; how much installation material is needed for a orifice plate, compared to how much is required for an electromagnetic flowmeter? Additionally, the range of measurement for orifice plates is smaller!
The system accuracy of orifice plate flowmeters is not as high as that of electromagnetic flowmeters
Electromagnetic flowmeter: easy to install and maintain, high precision, no pressure loss, simple structure, few failure points
The range ratio of electromagnetic flow measurement is also better than that of orifice plates
How can a orifice plate compare in terms of accuracy to an electromagnetic flowmeter? For measuring media such as circulating water, electromagnetic flowmeters are the preferred choice.
When the diameter is large, electromagnetic flowmeters are very expensive.
Orifice plates have a high failure rate and poor linearity; they are prone to freezing in winter. Electromagnetic valves are a good choice for medium and low flow rates, while they offer fewer advantages for large-diameter applications
The technology of electromagnetic flowmeters is already very mature, and those made in China are highly functional. The accuracy is better than that of orifice plates. The advantages of electromagnetic flowmeters are: 1. Low maintenance requirements ； 2. It has higher accuracy than orifice plates; its accuracy does not decrease over time due to wear at sharp edges like that of orifice plates, ensuring accurate calculation of material balance between devices. 3. It is easy to install in open areas, requiring only the connection of power and signal cables. There is no need to consider insulation or heating, as it is very inconvenient and costly to use steam or hot water for heating in open areas. The service life of electric heat tracing is also limited. 4. Large range ratio. Large-diameter pipes can use plug-in electromagnets.
