There are many types of flowmeters for measuring water flow, but there is no so-called perfect flowmeter that can be applied to the measurement of water flow under various working conditions. Each type of flowmeter has its own specific occasion. So, in the face of a wide variety of water flow meters, how should we choose?
For the relatively clean water medium, many types of flow meters can be measured. In contrast, the throttling flowmeter has a relatively large pressure loss, and the installation is more complicated. The installation and maintenance of the vortex flowmeter is simple, but the minimum flow rate it can measure is still large, the electromagnetic flowmeter is simple to install and maintain, and the flow range is wide Therefore, it is more appropriate to use electromagnetic flowmeter in this case.
For media with high impurity content, such as sediment, it is more appropriate to use an inserted electromagnetic flowmeter. After using the flowmeter, the pipeline should be cleaned regularly to prevent sediment from being deposited in the pipeline and affecting the measurement result.
For deionized water or high-purity distilled water, the deconductivity cannot reach the standard that can be measured by a general-purpose electromagnetic flowmeter. Therefore, an electromagnetic flowmeter cannot be selected, but a vortex flowmeter or an ultrasonic flowmeter should be selected.
For sewage, it is more appropriate to use electromagnetic flowmeter to measure. If it is corrosive sewage, such as industrial discharge sewage, you need to choose an electromagnetic flowmeter with a corrosion-resistant lining.
When choosing a water flow meter, we need to consider many factors, such as cleanliness, working conditions, etc. If you have any questions when choosing, you can consult us.
