First and foremost, it’s crucial to grasp the operational principles of an ultrasonic flowmeter, as well as the specifics of the pipe diameter, temperature, and medium being measured. These parameters—pipe diameter, medium type, and temperature—must be entered based on real-world application data. Filling them in arbitrarily can lead to significant errors, directly impacting the accuracy of your measurements. For optimal results, ensure that the outer diameter of the pipe is at least twice the thickness of its walls.
**Operating Procedures:**
1. **(PAR) Parameter Setting:** Begin by selecting either channel A or B. Input the pipe diameter, wall thickness, type of medium, and medium temperature. It's essential to ensure these values align with the conditions of your specific application.
2. **(MEA) Measurement Settings:** If you're using Channel A, activate it using the 2 and 8 keys. The system will then suggest the number of sound paths needed for proper measurement. An even number of sound paths requires the sensors to be installed on the same side of the pipe, while an odd number suggests they should be placed on opposite sides. Follow the system’s recommended sensor installation distances. Always use a coupling agent when mounting the sensors. For the S signal to function correctly, it should register above two grid lines. If it doesn’t reach this threshold, adjust the installation until it does. After confirming the correct spacing between sensors, the device will display the measured data. To view measurements in another unit, press the number 3 key.
3. **(OPT) Output Settings:** Choose the appropriate channel without ongoing measurements. Select the desired measurement quantity, specify the measurement unit, decide whether to save the data, and set the storage cycle.
**Precautions:**
1. When connecting the sensor to the main unit, align the red dots on the sensor connector with those on the corresponding slot. This ensures proper electrical connection.
2. The measured temperature must fall within the configured range. Using a normal-temperature sensor for high-temperature applications risks damaging the sensor due to overheating.
3. The pipe diameter under measurement must also remain within the configured limits.
4. For accurate readings, ensure the signal strength exceeds two measurements. This guarantees the reliability of your data.
5. Before installing the sensor, thoroughly clean the installation site and apply a suitable coupling agent. For metallic pipes like stainless steel or carbon steel, consider lightly sanding the area first to improve adhesion.
