What are the Advantages and Disadvantages of an Ultrasonic Flow Meter？

• Non-contact measurement: the biggest advantage of ultrasonic flow meter is that there is no need to contact the flow rate, can be non-contact measurement. This measurement can be avoided because of the contact flow rate and the resulting disturbance and resistance, so as to obtain more accurate results.

• High measurement accuracy: ultrasonic flow meter measurement accuracy is high, the general error is within ± 1%. At the same time, through the use of advanced technology such as the Doppler effect, can improve the measurement accuracy and stability, suitable for the flow measurement of high precision requirements of the occasion.

• Stable operation, no maintenance: ultrasonic flow meter in normal operation, usually has a long service life and low failure rate. In addition, because of its internal no moving parts, so there is no need for regular maintenance or replacement parts, greatly reducing the cost of use.

• Can measure a variety of fluids: ultrasonic flow meter can be used to measure gases, liquids and mixed fluids and other fluid media. In addition, through the selection of different sensor materials and measurement methods, can be adapted to a variety of fluid media and working conditions, with a wide range of applications.

• Not easily affected by the medium: ultrasonic flow meter does not contact the liquid, not easy to be affected by the nature of the liquid and the inclusion of debris, especially suitable for measuring corrosive, easy to scale and high viscosity liquid.

Ultrasonic flowmeter disadvantages

1. The measured fluid temperature is generally lower than 200 ℃, that is, the temperature measurement range is not high;

2. Poor anti-interference ability, ultrasonic flowmeter measurement data is susceptible to media containing air bubbles, pipe scaling, pumps, and other sound sources mixed into the ultrasonic noise interference, measurement accuracy is easily disturbed;

3. Pipeline vibration shadow effect: Although the ultrasonic flowmeter is a non-contact measurement equipment, but in some cases, pipeline vibration may have an impact on the measurement results. For example, in the case of unstable fluid flow or pipe vibration, may affect the reception and resolution of ultrasonic signals.

Ultrasonic flow meter with its unique advantages in specific applications excel, but in the choice, the user needs to take into account the characteristics of the fluid and the measurement environment on the accuracy of the impact to ensure the best measurement results.
