I. Understanding the WS Vertical Spiral Wing Water Meter

Unique Structure and Working Principle of the WS Vertical Spiral Wing Water Meter

The WS Vertical Spiral Wing Water Meter (often referred to as the WS Vertical Turbine Water Meter) is a velocity-type flow meter designed for the precise measurement of the total volume of water passing through a pipeline, typically in cubic meters. It falls into the category of medium-to-large caliber meters, specifically engineered for applications demanding high flow rates and minimal pressure loss, making it an essential device in water management and industrial metering.

Core Definition and Working Principle

The WS water meter operates on the principle of converting fluid kinetic energy:

Water Flow Impulsion: As water enters the metering chamber at a certain velocity, its kinetic energy drives the spiral wing (similar to a propeller or turbine) located within the chamber to rotate.

Spiral Wing Structure: The wing features a multi-bladed design optimized for the flow field, ensuring stable and efficient energy transfer from the water flow to the rotation.

Vertical Axis: The defining characteristic of the WS Vertical Spiral Wing Water Meter is that the rotational axis of the spiral wing is perpendicular to the horizontal axis of the pipe (i.e., perpendicular to the direction of water flow).

Accumulation and Measurement: The rotational speed of the spiral wing is strictly proportional to the instantaneous water flow rate passing through the meter. This rotation is accurately transmitted to the external, sealed register via a magnetic coupling or mechanical gear train, accumulating the total volume of water.

This structural design ensures that the meter maintains high accuracy and long-term reliability across a wide flow range.

Key Components and Their Functions in Water Measurement

The WS Vertical Spiral Wing Water Meter mainly consists of the following critical components, whose quality and design directly influence the meter's performance:

Why Choose “Vertical” Installation
