The scope of use of Single Jet Water Meter and Multi Jet Water Meter
At present, most of the smart water meters used in my country are multi-flow water meters. The only difference between single-flow water meters and multi-flow water meters is that the performance of multi-flow water meters is relatively stable and stable! This also determines the difference in the scope of application of single-flow water meters and multi-flow water meters.
First, a brief introduction to single-flow water meters and multi-flow water meters. Single-flow water meter: that is, the water flows into the movement from one direction and the kinetic energy of the water impinges the impeller. Long-term work may cause wear of the impeller, affecting the service life and measurement accuracy of the water meter. Take the multi-flow rotor wet cold water meter as an example: When it flows into the water meter movement, the force of the impeller is relatively uniform. The advantages of multi-flow water meters are precisely the disadvantages of single-flow water meters. At present, the smart water meters in my country all use multi-flow water meters. Next, let's take a look at the range of use of single-flow water meters and multi-flow water meters.
According to the brief introduction above, you can imagine that in areas with poor water quality, when the conditions such as flow rate, water pressure, etc. that affect the performance of the water meter are the same, what will happen to the two water meters when they work for a long time? How will the application range of single-flow water meters and multi-flow water meters be affected? The result is of course that the single-flow water meter is gradually clogging the movement, while the multi-flow water meter will not be greatly affected. Because the water quality is poor, the impurities in the water are relatively large, and the particles of impurities are relatively large. The single-flow water meter has only one water inlet, which is the only channel that the water flow must pass through. The water inlet of the single-flow water meter is blocked by impurities, then The life of the water meter will end. The multi-flow water meter is different. Each water inlet enters water at the same time. Even if impurities block one water inlet, the water flow can enter the water meter movement from other channels so that the water meter can still work normally.
From this, the scope of use of single-flow water meters and multi-flow water meters is summarized: single-flow water meters have relatively high requirements on water quality, and are suitable for installation in areas with better water quality and less impurities; multi-flow water meters have lower requirements for water quality, which That is why most of the smart water meters in my country now use multiple flow rates.
