Mechanical Wolttman Dry Dial Type Flow Meter Specification

Introduction

Woltman meters are Dry Dial Magnetic Driven Turbine Flow Meters measure the velocity of the water flowing

through with the help of a turbine. The volume is mechanically calculated, through the known section area and

indicated with the roller counters in cubic meters.

In the horizontal axis Woltman meters, the turbine shaft is arranged parallel to the axis of the pipeline. The rotation

of the turbine is transmitted through a worm gear to the dry dial counter. A very robust construction, little head loss.

Industrial meters bulk type magnetic drive as per ISO 4064 flange end. Dry dial, Magnetic Drive Measuring Accuracy

Conforming to ISO 4064 CLASS-B Interchangeable Spare Parts for easy maintenance
