At present, most of the water meters in use in China are mechanical water meters, since the mechanical water meter has such a large market share, "existence is reasonable", which is enough to show that the mechanical water meter is especially valuable. The ultrasonic water meter is a latecomer, it is expected that in the next few years, ultrasonic smart water meter will usher in explosive growth, the following are introduced to the advantages of these two types of water meters.
It should be noted that here into the introduction of their advantages, as for the shortcomings, here is not much to elaborate:
Mechanical water meter is the use of mechanical measuring elements to continuously divide the fluid into a single known volume part, according to the metering chamber one by one, the number of times repeatedly filled and discharged that volume part of the fluid to measure the flow of the volume of the total. Its main advantage is that it is low cost, inexpensive, does not require a high level of technology, and it is very easy to promote.
Ultrasonic water meter using ultrasonic waves in the flow of liquid propagation contains the principle of fluid flow information, through the detection of ultrasonic signals through the fluid can be obtained by the measured fluid flow rate information, and finally converted to flow according to the corresponding principle. Ultrasonic water meter is measured in the pipeline without any moving, flow-blocking parts, no wear and tear, small pressure loss. High sensitivity, can detect small changes in the flow rate. At the same time, the measured medium is almost no requirements, has a very wide range ratio, and ultrasonic water meter structure is simple, easy to maintain, very suitable for civil and industrial measurement.
It can be said that the mechanical water meter and ultrasonic water meter have their own advantages, it should be noted that, with the water supply management departments at all levels began to lay out the "wisdom of water", the future trend of the water meter is to the development of intelligent water meters. At this point, the ultrasonic water meter is more advantageous.
