Liquid Turbine Flowmeter

GENERAL INFORMATION

The liquid turbine flowmeter operates by directing the flow against a multi-bladed rotor, causing it to spin at a speed directly proportional to the volumetric flow rate. The blade passages are detected non-intrusively by a magnetic or RF pickup, generating a frequency signal that is converted into flow rate and totalized volume. Offering high accuracy, excellent repeatability, and fast response, it is ideally suited for clean, low-viscosity liquids such as refined petroleum products, chemicals, solvents, and water. Typical applications include custody transfer, blending, batching, and pipeline monitoring in the oil & gas, petrochemical, water treatment, food & beverage, and pharmaceutical industries.

BRIEF INTRODUCTION

The liquid turbine flow sensor (hereinafter referred to as sensor) is based on the principle of torque balance and belongs to the velocity-type flow meter. The sensor has the characteristics of simple structure, lightweight, high precision, good repeatability, sensitive response, convenient installation and maintenance, etc. It is widely used in petroleum, chemical, metallurgy, water supply, papermaking, and other industries. It is an ideal instrument for flow measurement and energy saving.
