Vertical Helical Turbine Cold And Hot Water Meter
This is a type of mechanical water meter that is widely used in conditions of high flow rate and medium to low pressure. It is a kind of velocity water meter that calculates the flow rate by measuring the speed of water flow.
| Characteristics | Vertical helical water meter | Horizontal helical water meter (detachable type) |
|---|---|---|
| Installation method | Must be vertical, flow direction from bottom to top | Installed horizontally (can also be vertical, but with a different structure) |
| Pressure loss | Smaller | Larger |
| Structure | One-piece, compact structure | Detachable, easy to maintain (the mechanism can be pulled out) |
| Requirements for installation space | High requirements in height direction | High requirements in length direction |
| Performance at high flow rates | Excellent | Excellent |
| Performance at low flow rates | Better | Ordinary |
| Mainstream diameters | DN40 - DN200 | DN50 - DN300+ |
Vertical helical turbine cold and hot water meters are the "powerhouses" and "low-resistance pioneers" in the mechanical water meter family. With their unique vertical structure, they achieve efficient, low-resistance, and stable measurement under high-flow conditions, making them a classic and reliable choice for medium and large-diameter water supply metering scenarios.
They represent a peak in mechanical metering, and now, through integration with Internet of Things (IoT) technology, they are evolving from a "reliable mechanical heart" to an "intelligent network data node", continuing to play a key role in the smart water system. For engineers and water management professionals, understanding their principles, advantages, and strict installation requirements is the foundation for ensuring their long-term accurate and stable operation.
