ARAD WST Woltman Silver Turbo 200mm Flanged Water Meter

Woltman turbine water meter, 200mm flanged connection, wide flow range, high accuracy, heavy-duty industrial design

The ARAD WST Woltman Silver Turbo 200mm Water Meter is a high-capacity bulk flow meter designed for precise and reliable water measurement in municipal, agricultural, and industrial systems. Utilizing advanced Woltman turbine technology, it ensures accurate performance across both low and high flow conditions.

Engineered with a unique measuring unit, the meter features only one moving element in contact with water, minimizing wear and ensuring long-term operational reliability. The magnetic coupling system provides stable measurement while protecting the register from environmental exposure.

Constructed with a robust cast iron body and polyester coating, along with stainless steel internal components, the meter is built for durability in demanding environments. It is highly resistant to vibration and humidity, ensuring consistent performance under harsh operating conditions.

The 200mm flanged connection allows secure installation in large pipeline systems. The IP68-rated sealed register ensures clear readability and protection against dust and water ingress, while the wide measuring range enables accurate monitoring across varying flow rates.
