Ultrasonic flow meters measure the speed of liquid or gas using sound frequencies to determine flow rates. Ultrasonic flow meters are used for measuring almost all light homogeneous fluids including water, wastewater and hydrocarbons.

Different technology of ultrasonic flow meters

Doppler
Transit time

Advantages of ultrasound flow meters

• measuring flow rates from outside the pipe, without breaking the flow or process.
• no moving parts
• non-invasive liquid flow monitoring
• accuracy of measurements does not depend on temperature or pressure of fluids
• cheap maintenance
• wide range of pipe sizes and process temperatures

Ultrasonic flow meter principle of operation

Ultrasonic Flow Meter consists of two sensors.

Typical applications:

• waterdistribution flow-metering
• wastewater flow-metering
• building services
• chemical industry
• pump inspection
• food flow-monitoring
• steel industry
