Product Description

Application:

The Woltman Type Water Meter delivers precise, high-volume flow measurement for demanding industrial and commercial applications, with stable performance and minimal pressure loss.

Key Features:

• Removable Mechanism: Easy maintenance without removing the body.

• Woltman Precision: High flow capacity with minimal pressure loss.

• Sealed Register: Dry-dial counter stays clear and fog-free.

• Industrial Strength: Robust cast iron body with epoxy coating.

• Interchangeable Parts: Standardized components for easy replacement.

• Low Pressure Loss: Optimized flow design to minimize energy costs and pumping pressure.

• High Flow Capacity: Handles heavy-duty industrial loads and peak flow surges reliably.

• Pulse Ready: Pre-equipped for reed switch or inductive pulse output.

Installation:

• Best installed horizontally with the register facing up for maximum accuracy.

• Maintain 10×DN upstream and 5×DN downstream to ensure stable water flow.

• Water must flow strictly in the direction of the arrow cast on the body.

Accuracy:

• From minimum flow rate (Q1) inclusive, to transitional flow rate (Q2) exclusive: ±5%

• From transitional flow rate (Q2) inclusive, to overload flow rate (Q4) exclusive: ±2%

• Hot water meter ±3%
