Vertical Screw Wing Series Water meter Product introduction
Vertical Screw Wing Series is a detachable vertical screw-wing water meter with direct reading and remote transmission technology. It has the advantages of high measuring accuracy, wide measuring range, large circulation capacity and long service life. This series of products adopt multi-seal structure: Firstly, the seal counter is designed as mechanical seal, which effectively avoids the pressure difference between inside and outside of vacuum seal and many unfavorable factors. At the same time, in order to prevent the condensation phenomenon of the residual air in the seal counter caused by mechanical seal during the alternation of cold and heat, it will produce to the circuit. Components cause certain damage, the sealed counter is equipped with a desiccant as a two-way waterproof and moisture-proof way, which effectively protects the circuit components; secondly, in order to prevent the sealed counter from entering the sealed counter due to external water pressure or humid air, the mechanical seal structure is also used for the outer part of the sealed counter and the remote transmission line part. At the same time, in order to remove the residual air brought by the external seal, two special spaces for drying agent are designed inside the flange as external waterproof and moisture-proof methods. This sealing structure will seal all possible inlets of water and moisture inside and outside the sealed counter. The dust-proof and water-proof grade reaches IP 68. Even if immersed in water for a long time, it will not affect the normal reading and remote signal output. The transparent cover of the sealed counter adopts the structure design with amplification function, which makes the reading easier to read. The machine core is designed as a detachable structure, so that the water meter does not need to be removed from the road, and the machine core can be taken out for repair or replacement and maintenance.
Vertical Screw Wing Series can add valves, increase pressure sensing, support IC card, LoRa, NB-IOT, photoelectric transmission, etc.

Main Performance Characteristics
1.Vertical screw-wing water meter concentrates the advantages of horizontal screw-wing water meter and rotary-wing water meter. Using full flow detection, the measured water flow is axial flow, low in and out, and the measurement accuracy is very high, especially at low flow, the accuracy is higher than other types of water meter.
2.In the structure design of vertical screw-wing water meter, the turbo-scroll transmission mechanism is cancelled, and the counter is driven directly by the impeller, so the initial flow rate is very low.
3.Vertical screw-wing water meter uses built-in stainless steel filter to ensure long-term stability of the product.

Installation and Use of Vertical Screw Wing Water Meter
1. Choosing the caliber of water meter should be based on the caliber of pipeline and the flow rate equal to or less than the common flow rate of water meter.
2. When the water meter is installed and used, the upstream valve should be opened slowly to avoid the phenomenon of water hammer caused by rapid opening, which will cause serious damage to the water meter.
3. Installation location should avoid exposure, freezing and flooding, and facilitate disassembly, assembly and meter reading. During the freezing period, besides wrapping the water meter and water pipe, close the water meter inlet valve when not in use, and open the water outlet valve and faucet to prevent the water meter from being damaged by frozen expansion.
4. The water meter must be installed horizontally (vertically) so that the surface is literally upward and the arrow on the case is in the same direction as the flow.
5. The newly installed pipeline must wash the stones, mud and silk debris in the pipeline before installing the water meter, so as to avoid causing water meter malfunction.
6. Water meters should not be directly connected with pipelines. There should be flexible joints between water meters and pipelines (pipe joints, connecting nuts, nozzle sealing gaskets). When disassembling and assembling the water meter, it must not be hard pulled to avoid damaging the water meter.
7. If the cold water meter is installed at the inlet pipe of the boiler, it should prevent the hot water reflux from burning the water meter.
8. When the water meter is used for a long time, impurities and rust in the pipeline will block the filter screen or enter the meter, which will increase the error of the water meter or affect its normal operation. Therefore, it is necessary to clean the water meter every other time and recalibrate it quickly or slowly, but it is not allowed to disassemble and assemble it by itself.
9. When not in use, for example, the small fluctuation of the water meter is caused by the unstable flow pressure in the pipeline or other reasons;
In order to measure accurately, the installation of horizontal installation water meter outlet pipeline should be no less than 0.5 meters higher than that of water meter.
