Product Description

Large Caliber DN400-DN600 Ductile Iron Flanged Woltman Detachable Cold Water Meter

The Woltman water meter is a type of velocity water meter that is widely used for measuring the flow rate of water in large pipes. It gets its name from the German engineer Reinhard Woltman, who invented the meter in the 19th century. The Woltman meter consists of a rotor with several blades that spins as water flows through it. The spinning rotor drives a mechanical counter that registers the volume of water passing through the meter. The Woltman meter is known for its accuracy and reliability, and it is commonly used in municipal water supply systems, irrigation systems, and industrial applications where large volumes of water need to be measured.

Application

Measuring the volume of cold(hot) water passing through the pipeline.Water meter is used for home or apartment

Features

·High Flow Rates: Woltman meters have a high flow rate capacity, making them suitable for use in large diameter pipes.
Accuracy: With highly precise and calibrated mechanisms, Woltman meters provide accurate measurements of water flow rates.
·Low Head Loss: Woltman meters have low head loss, meaning they do not significantly alter the pressure of the flowing water, which is important in maintaining the efficiency of the overall system.
·Longevity: The Woltman meter is built to last a long time with minimal maintenance needs, ensuring that it provides reliable service for many years.
·Easy Installation: Woltman meters are easy to install and can be integrated into existing pipelines with minimal disruption.
·Robust Construction: The Water Meter is constructed using high-quality materials (such as cast iron or plastic) which makes it durable and able to withstand harsh environmental conditions.
