Smart Large Diameter Water Flow Meter with Prepaid Remote Control and Lora/Lorawan/4G, Cold/Hot, DN50/DN80/DN100/DN150/DN200

Product Description

Product Overview
WS Type Vertical Screw Wing Large Diameter Industrial Water Meter has a built-in stainless steel filter screen, which is suitable for industrial water environment, and is suitable for water metering in situations with large flow changes.It combines the advantages of horizontal screw wing water meter and rotor wing water meter, and adopts full flow detection. The measured water flow is axial flow, low in and high out, with high measurement accuracy. Under low flow, the accuracy is higher than other types of water meters.
In the structural design, the wet liquid seal water meter eliminates the worm gear and worm drive mechanism, and the counter is directly driven by the impeller, so the starting flow is extremely low.The stainless steel built-in filter screen design eliminates the need to install a filter screen, ensuring the long-term stable operation of the product.
Main features
1. The detachable movement structure is adopted, which is convenient for maintenance, wide range, and suitable for occasions with large flow changes.
2. Different calibers, different movements, full flow detection, high measurement accuracy.
3. The built-in structure of the regulating mechanism effectively prevents the meter from being adjusted privately.
4. The high wear resistance bearing system ensures the long-term stability and reliability of the product, and significantly improves the maximum flow of the product.
5. The overall performance of the six digit digital wheel reading is better than that of the LXS rotorcraft water meter.
6. Epoxy resin powder coated shell and stainless steel fasteners are used to maximize rust prevention and prolong service life.
7. It can be equipped with an anti prying protective cover. During installation, it is not necessary to install a straight pipe section before and after the meter, and it is not necessary to install a filter screen. It is installed horizontally.
8. Magnetic dry-type counter can be configured to ensure cleanness and clear display.It can be configured with transmission counter, multiple pulse signal output (single/double/triple reed, LED, metal sensor, Hall element).
