Surefix Woltman Bulk Water Meter

High-Performance Bulk Water Meter for Municipal & Industrial Applications

The Surefix Woltman Water Meter is a heavy-duty mechanical bulk water meter engineered to deliver precise and reliable measurement of high-volume water flow across municipal water distribution systems, industrial facilities, commercial buildings, water treatment plants, and agricultural irrigation networks.

Designed in accordance with ISO 4064 Class B, this flanged water meter combines robust construction with dependable metering performance. The dry-dial magnetic drive mechanism ensures accurate readings while protecting the register from moisture and condensation, maintaining excellent visibility throughout the product’s service life.

One of the key advantages of the Surefix Woltman Water Meter is its removable measuring mechanism, allowing maintenance and servicing without removing the entire meter body from the pipeline. This significantly reduces downtime and maintenance costs, making it an ideal solution for utility operators and industrial facilities.

The vacuum-sealed register prevents fogging while ensuring long-term readability. Selected high-quality materials provide excellent corrosion resistance, low pressure loss, and reliable performance under continuous high-flow operating conditions.

The meter is available for both cold and hot water applications and supports optional pulse output for integration with AMR (Automatic Meter Reading) and utility monitoring systems.
