Flow

Overview

Vortex Flow Meter is based on “Karman” principle. It is a kind of the vibration meters. With simple configuration and install conveniently. It can measure and control various liquid (e.g.: water, oil, petroleum, alcohol, acid, alkali and different chemical fluids), gas (e.g.: air, oxygen, N2, natural gas, coal gas), and steam (e.g.: saturation steam, overheated water vapor).

Features

• Wide Measurement Range: Capable of measuring a broad range of flow rates, making them versatile for different applications.
• High Accuracy: Offers precise measurements with accuracy typically around ±1% of the flow rate.
• Low Maintenance: Few moving parts result in lower maintenance requirements and longer service life.
• Wide Temperature Range: -40℃～+400℃
• Multi-Fluid Capability: Can measure different types of fluids, including liquids, gases, and steam.
• Digital Output Options: Available with various output formats, including 4-20 mA, pulse output, and digital communication protocols (like Modbus).
• Integrated Temperature and Pressure Measurement: Some models offer additional sensors to monitor temperature and pressure, enhancing overall process control.
