Ultrasonic, Magnetic & Coriolis Flow Meters – Working Principle & Delhi Supplier Guide by Udhhyog

 Accurate flow measurement is essential across industries like water treatment, oil & gas, chemical processing, and HVAC. Among the most advanced and reliable options are ultrasonic, magnetic, and coriolis flow meters.

This guide covers:

• The working principle of each meter

• Advantages and applications

• Flow transmitter features

• Why Udhhyog is Delhi’s leading supplier of these industrial flow meters

1. Ultrasonic Flow Meters – Working Principle

Ultrasonic flow meters use high-frequency sound waves to measure the flow rate of a liquid or gas.

🔧 Two Main Types:

• Transit-Time: Measures time difference between ultrasonic signals sent upstream and downstream.

• Doppler: Detects frequency shift caused by particles or bubbles in the flow.

✅ Key Benefits:

• Non-invasive (clamp-on)

• No moving parts → Low maintenance

• Suitable for clean and dirty fluids

📌 Common Applications:

• Municipal water supply

• Chilled water lines (HVAC)

• Oil, diesel, and chemical flow

2. Magnetic Flow Meters – Working Principle

Magnetic (Electromagnetic) flow meters work on Faraday’s Law of Electromagnetic Induction. As conductive fluid flows through a magnetic field, it induces voltage that is proportional to flow velocity.

✅ Key Benefits:

• No obstruction → Zero pressure loss

• Accurate for conductive fluids

• Long service life with low maintenance

📌 Common Applications:

• Water & wastewater treatment

• Food & beverage

• Pulp & paper industry

3. Coriolis Flow Meters – Working Principle

Coriolis flow meters measure mass flow by utilizing the Coriolis effect. When fluid flows through vibrating tubes, the twisting (phase shift) helps determine the mass flow rate directly.

✅ Key Benefits:

• Direct mass flow measurement

• Also measures temperature and density

• Extremely high accuracy (±0.1%)

📌 Common Applications:

• Oil & gas custody transfer

• Pharmaceutical dosing

• Chemical blending

Flow Transmitters & Output Options

All three meters are available with digital flow transmitters featuring:

• 4–20 mA analog output

• HART/Modbus communication

• Totalizer & LCD display

• Data logging capability
