Vertical Woltman Helix Water Meter

Introduction

Stepping away from the conventional, our Woltman helix water meter with vertical installation brings a fresh perspective to large-diameter pipeline metering. This meter is known for its dynamic flow handling and minimal pressure impact. When water courses through this meter, it drives the uniquely shaped helical impeller in an axial flow, converting the water's velocity into a quantifiable volume displayed on the meter.

Applications

From the kitchen to the bathroom, Woltman helix water meters are ideal for metering household water usage
Tracks water flow in commercial establishments and light industrial facilities
These water meters are a reliable choice for water measurement in schools, hospitals, and other public institutions

Working Conditions

Suitable for cold water ≤50℃

Water pressure ≤1MPa, 1.6MPa

Upstream & downstream flow field sensitivity class: UO DO

Features

Vertical Woltman helix water meter reduces friction and enhances lifespan
A stainless steel strainer is built into the meter, saving the cost and hassle of external filters
Capable of handling a variety of flow rates, making it versatile for multiple applications
Equipped to adapt to modern metering needs with options for remote data transmission
