ARAD WST Woltman Silver Turbo 65mm Flanged Water Meter

Woltman turbine water meter, 65mm flanged connection, wide flow range, high accuracy, durable industrial construction

The ARAD WST Woltman Silver Turbo 65mm Water Meter is a high-performance bulk flow meter designed for accurate and reliable water measurement in municipal, agricultural, and industrial systems. Utilizing advanced Woltman turbine technology, it delivers precise measurement across both low and high flow conditions.

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

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

The 65mm flanged connection enables secure installation in pipeline systems. The IP68-rated sealed register ensures clear readability and protection against dust and water ingress, while the wide measuring range allows accurate monitoring across varying flow rates.
