2024-11-19
Flow meters play a crucial role in fluid measurement across industries. VACORDA offers a diverse range of flow meters, each tailored to specific needs. This article compares five popular types of flow meters—Metal Tube Rotameters, Electromagnetic Flow Meters, Coriolis Mass Flow Meters, Vortex Flow Meters, and Differential Pressure Flow Meters—to help you choose the best solution for your application.
1. Metal Tube Rotameter
Applications: Suitable for liquids and gases.
Display Options: Pointer or LCD display.
Output Signal: 4-20mA, pulse signals.
Alarm Function: Equipped with alarm switches.
Communication Protocols: HART, MODBUS.
Metal Tube Rotameters are versatile, cost-effective solutions for measuring flow in low to medium-pressure systems. Their robust construction and ability to display readings directly on-site make them ideal for industrial applications.
2. Electromagnetic Flow Meter
Applications: Conductive liquids only.
Display Options: LCD display for real-time flow data.
Output Signal: 4-20mA, pulse signals.
Alarm Function: Not included.
Communication Protocols: HART, MODBUS.
Electromagnetic flow meters are known for their high precision and are ideal for measuring the flow of conductive liquids such as water, chemicals, and slurries. They are widely used in industries like water treatment and chemical processing.
3. Coriolis Mass Flow Meter
Applications: Suitable for both liquids and gases.
Display Options: LCD display.
Output Signal: 4-20mA.
Alarm Function: Not included.
Communication Protocols: HART, MODBUS.
Coriolis Mass Flow Meters excel in measuring mass flow and density with exceptional accuracy. They are perfect for applications requiring precise measurements, such as oil and gas, food and beverage, and pharmaceutical industries.
4. Vortex Flow Meter
Applications: Suitable for liquids and gases.
Display Options: LCD display.
Output Signal: 4-20mA, pulse signals.
Alarm Function: Not included.
Communication Protocols: HART, MODBUS.
Vortex Flow Meters offer a durable solution for measuring flow in high-pressure environments. Their ability to measure a wide range of fluids with minimal maintenance makes them a popular choice in steam and energy applications.
5. Differential Pressure Flow Meter
Applications: Suitable for liquids and gases.
Display Options: LCD display.
Output Signal: 4-20mA.
Alarm Function: Not included.
Communication Protocols: HART, MODBUS.
Differential Pressure Flow Meters are widely used in applications that require reliable and cost-effective flow measurement. They are commonly found in industries such as HVAC, oil and gas, and chemical processing.
