1. Which type of flowmeter is best to use? Ultrasonic water measurement is a relatively simple flow measurement method, usually installed externally. This method is not only easy to install, but also has low requirements for the pipeline itself. However, it is worth noting that the accuracy of ultrasonic flow meters is relatively low and may not be suitable for applications that require high measurement accuracy. In the domestic market, there are several well-known manufacturers in the field of ultrasonic flow meters. For example, Dalian Haifeng, Daosheng, Tangshan Huizhong, and Shenzhen Jianheng. These manufacturers products each have their own characteristics, and users can evaluate and select based on specific needs when choosing. The external installation method makes the application of ultrasonic flow meters more flexible. This method does not require tedious modifications to the pipeline and can be quickly installed and put into use. This is very advantageous for situations that require rapid deployment of traffic measurement systems. Although ultrasonic flow meters perform well in terms of installation convenience, their accuracy issues cannot be ignored. When choosing an ultrasonic flowmeter, users should weigh the relationship between installation convenience and measurement accuracy based on the needs of the actual application scenario. For applications that require high precision, other types of flow meters may need to be considered. In summary, ultrasonic flow meters, as a convenient flow measurement tool, have certain market advantages. However, users also need to consider factors such as accuracy and cost when choosing, in order to find the most suitable flowmeter for themselves.

2. What are the precautions for the application of ultrasonic flow meters?

Shanghai Hongke Automation Instrument Co., Ltd. TFXD External Clamp Time Difference Ultrasonic Flow Meter Ultrasonic Flow Meter Installation and Use Precautions:

1. The input pipeline parameters must be correct and consistent with the actual situation, otherwise the flow meter cannot work normally.

2、 When installing an external clamp sensor, use a lot of coupling agent to stick the sensor to the pipeline wall. While checking the signal strength and signal quality values displayed by the host, slowly move the sensor near the installation point until the strongest signal and maximum signal quality value are received. The larger the diameter of the pipeline, the greater the range of sensor movement. Then confirm whether the installation distance matches the sensor installation distance given by M25, and whether the sensor is installed on the same straight line as the pipeline axis. Pay special attention to pipes made of rolled steel plates, as these pipes are irregular. If the signal strength is always marked as 0.00, it indicates that the flowmeter has not received the ultrasonic signal. Check whether the parameters (including all parameters related to the pipeline) are input correctly, whether the sensor installation method is selected correctly, whether the pipeline is too old, whether its lining is too thick, whether there is fluid in the pipeline, whether it is too close to the valve elbow, whether there are too many bubbles in the fluid, etc. If it is not for these reasons, the signal cannot be received, so we have to try another measurement point or choose a plug-in sensor.

3、 Confirm whether the flowmeter is working properl
