Characteristics of single jet water meters and multi jet water meters
Single-jet 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 water meter as an example: water flows from all directions 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 above brief introduction, 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? Single-flow water meters How will the application range of the multi-flow water meter be affected? Of course, the result is that the single-flow water meter is gradually blocking 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 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 the 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.
