How to choose a clamp-on Transmit time or Doppler ultrasonic flowmeter

Ultrasonic flow meters are inferential meters that use ultrasonic technology to measure the velocity

of an acoustically conductive liquid moving through it. There are two types of ultrasonic flow meter

technologies, including Doppler and transit time. re inferential meters that use ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it. There are two types of ultrasonic flow meter technologies, including Doppler and transit time. In addition to inline models, ultrasonic meters are available as clamp-on solutions when contact with the measured fluid is not possible.When choosing a clamp-on ultrasonic flowmeter, the following factors can be considered: 

1. Flow range: Determine the flow range that needs to be measured, and choose the clamp-on ultrasonic flowmeter to ensure that it can cover the flow range that needs to be measured.

2. Fluid medium: Determine the fluid medium that needs to be measured. The clamp-on ultrasonic flowmeter can be applied to various fluid media, but attention should be paid to the handling of special media, such as high-temperature, high-viscosity media.

3. Pipe size: To determine the size of the pipe, the clamp-on ultrasonic flowmeter needs to match the pipe, and select the appropriate size to ensure accurate measurement.

4. Accuracy requirements: Select the clamp-on ultrasonic flow meter according to the measurement accuracy requirements. Different types of flowmeters have different accuracy requirements.

5. Communication interface: If remote monitoring or data acquisition is required, choose a clamp-on ultrasonic flowmeter with a suitable communication interface, such as RS485, Modbus, etc.

6. Cost considerations: According to budget constraints, choose a suitable clamp-on ultrasonic flowmeter.

During the selection process, you can refer to the product manuals and technical parameters of different models, or consult professional flowmeter suppliers or technical personnel for advice.
