Description

The Diehl Metering WESAN WP G is a Woltmann bulk water meter built to measure high flow rates in supply and distribution lines while keeping pressure loss low. A helical-vane turbine drives a sealed, encapsulated register, and the calibratable measuring insert can be exchanged in the field without removing the meter body.

Available from DN50 to DN300 for horizontal or vertical pipework, it combines MID-approved accuracy with a rugged, IP68 glass/copper counter. Its head unit rotates 350° for easy reading, and the meter is ready to go smart with clip-on IZAR RADIO or IZAR PULSE modules.

Key Features

High Flow, Low Pressure LossWoltmann design handles permanent flow up to 1600 m³/h with minimal head loss in supply lines.

Exchangeable, Calibratable InsertThe sealed measuring insert can be swapped and recalibrated in the field for long service life and accuracy.

Rugged & Tamper-ResistantIP68 encapsulated glass/copper counter with a 350° rotatable head and strong protection against magnetic manipulation.

Smart-Metering ReadyAdd automated reading at any time with clip-on IZAR RADIO (wireless) or IZAR PULSE (pulse output) modules.

Typical Applications

•Water distribution mains: bulk measurement on municipal supply and transmission lines.

•District metering & pumping stations: monitor zone inflows for balancing and water-loss analysis.

•Industrial & bulk supply: high-throughput metering for plants, utilities and large consumers, horizontal or vertical.
