Special Rotary Vane Wet Type Water Meter

Updated: 2026-07-18

Overview

The Special Rotor Wet-Type Water Meter is a widely used device for measuring water flow in various settings, from residential buildings to large industrial complexes. Its design incorporates a wet-type rotor, which ensures consistent performance even in challenging environments. This meter is favored for its precision and longevity, making it a reliable choice for utilities and businesses. Unlike dry-type meters, the wet-type mechanism reduces friction and wear, enhancing durability. The meter's construction typically includes corrosion-resistant materials like stainless steel and brass, ensuring it can withstand prolonged exposure to water without degradation.

Structure and Working Principle

The water meter consists of a rotor assembly housed within a sealed chamber, connected to a counting mechanism. As water flows through the meter, it drives the rotor, which in turn moves the counting dial to record consumption. The wet-type design means the rotor operates submerged in water, reducing mechanical resistance and improving accuracy. The internal components are precision-engineered to minimize pressure loss and maintain consistent flow measurement. Advanced models may include digital interfaces for remote monitoring, though mechanical versions remain popular for their simplicity and reliability.

Key Features

One of the standout features of this water meter is its high accuracy, often complying with international standards such as ISO 4064. The wet-type rotor ensures minimal wear, translating to a longer service life compared to dry-type meters. Additionally, the meter's materials are selected for corrosion resistance, making it suitable for both clean and slightly contaminated water. Other notable features include low maintenance requirements and compatibility with a wide range of pipe diameters. Some models offer tamper-proof designs to prevent unauthorized adjustments, ensuring billing accuracy.

Application Areas

This water meter is versatile, finding use in residential complexes, commercial buildings, and industrial facilities. It is particularly common in municipal water supply systems, where accurate measurement is critical for billing and resource management. Industries such as agriculture and manufacturing also rely on these meters for monitoring water usage in processes. In residential settings, the meter's durability and low maintenance make it a cost-effective solution for long-term use. Its ability to function reliably under varying flow rates further broadens its applicability across different sectors.

Maintenance and Precautions

Regular inspection is recommended to ensure the meter remains free of debris and sediment, which can affect accuracy. Although the wet-type design is robust, exposure to freezing temperatures should be avoided to prevent damage to the internal components. Proper installation by qualified personnel is essential to avoid leaks and ensure optimal performance. For industrial applications, periodic calibration may be necessary to maintain precision, especially in environments with high particulate content in the water. Most manufacturers provide guidelines for maintenance intervals and procedures.

B2B Procurement Guide

When procuring these water meters in bulk, buyers should prioritize suppliers with a proven track record in quality and compliance. Key considerations include the meter's accuracy class, material specifications, and certification from recognized bodies like ISO or AWWA. Bulk orders often come with discounts, but it's crucial to verify lead times and after-sales support. Customization options, such as specific pipe fittings or digital interfaces, should be discussed with the supplier. Additionally, buyers should request product samples and test reports to validate performance before committing to large purchases.
