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:

• Open-Flow Design: Paddle wheel structure prevents clogging from sand or weeds.

• Low Pressure Loss: Large flow passage ensures minimal energy consumption.

• Removable Mechanism: Easy on-site cleaning and maintenance without pipe removal.

• High Durability: Robust cast iron body with anti-corrosive epoxy coating.

• Sealed Register: Dry-dial counter ensures clear reading in muddy environments.

• Pulse Ready: Pre-equipped for remote monitoring and automated irrigation systems.

• Tamper Proof: Magnetic drive protected against external interference.

• Wide Range: High measurement accuracy for both low and high flow rates.

Specifications:

• Flange connecting option: ISO/ DIN/ ANSI

• Pulse output option: 1P=100-1000L

• Register: Copper-sealed/ Plastic-sealed

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.

• Ensure a strainer is installed upstream to prevent stones or weeds from damaging the paddle wheel.

• 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%
