Mechanical positive displacement water meter with stainless steel body and threaded connection. It features high measurement accuracy and strong anti-interference capability, and is not affected by water flow patterns. Suitable for civil residences, commercial buildings and special water quality scenarios, it can accurately capture small-flow water use and ensure fair and reliable water fee accounting.
Performance
1. High and Stable Measurement Accuracy: Adopts a positive displacement piston/rotating chamber structure, which is not affected by water flow patterns or pressure fluctuations. It maintains high metering accuracy within ±1% in both low and high flow ranges, far superior to traditional vane-type water meters, and is especially suitable for precise metering of small flow rates.
2. Strong Anti-interference and Anti-fouling Capability: The internal chamber design can effectively filter impurities in water and reduce the risk of clogging. The meter body is made of stainless steel, with excellent corrosion resistance and anti-magnetic interference performance, preventing external magnetic fields or water quality fluctuations from interfering with measurement results.
3. Reliable Operation and Long Service Life: The core moving parts adopt a combination of wear-resistant engineering plastics and stainless steel, with low friction loss. It can operate stably for more than 15 years in environments ranging from -10℃ to 60℃, without frequent calibration or maintenance, significantly reducing the full-life cycle cost of use.
Application
1. Civil Residential Household Metering: Widely used in household water supply metering for apartments, villas and other residences, accurately capturing small-flow water use such as washing and laundry, avoiding “idling” and undercounting, ensuring fair and transparent water fee accounting, and improving user satisfaction.
2. Commercial and Public Service Scenarios: Suitable for water metering in commercial and public buildings such as hotels, office buildings and schools. It can cope with complex water use conditions and intermittent water demand, accurately count water consumption in various areas, and provide reliable data for energy-saving management and cost accounting.
3. Adaptation to Special Water Quality and Environments: Can be used for metering special water quality such as purified water and softened water, and can also adapt to harsh environments such as cold and humidity. It performs stably and reliably in scenarios such as centralized heating water replenishment and direct drinking water systems in northern China.
Specifications
1. Caliber and Connection Method: Covers common civil calibers such as DN15, DN20, DN25, adopts threaded connections, complies with international standards such as ISO 4064, adapts to various pipes such as PPR and stainless steel, and is flexible in installation with good sealing performance.
2. Flow and Pressure Ratings: The nominal pressure is 1.6MPa, and the overload flow can reach 1.6 times the nominal flow. The common flow range covers Q1~Q3 levels, and the minimum starting flow is as low as 0.5L/h, meeting the full-range metering demand from dripping to full flow.
3. Material and Protection Level: The meter body is made of 304/316 stainless steel, the cover is made of ABS engineering plastic, and the seals are made of food-grade silicone rubber. The protection level reaches IP68, which can adapt to harsh environments such as humidity, dust and even temporary immersion, ensuring long-term stable operation.
