First and foremost, it's crucial to grasp the operational principles of an ultrasonic flowmeter, as well as the relevant parameters like pipe diameter, temperature, and medium. These values must be entered based on real-world application data; arbitrary inputs can lead to inaccuracies, directly impacting the precision of your measurements. Typically, the outer diameter should be at least twice the wall thickness.
Operating Procedures:
1. **(PAR) Parameter Settings**: Choose between Channel A or B, then input the pipe diameter, wall thickness, type of medium, and medium temperature. Make sure these match your specific application conditions.
2. **(MEA) Measurement Settings**: If using Channel A, activate it via the 2 and 8 keys. The system will suggest the optimal number of sound paths—odd numbers require sensors to be installed on opposite sides, while even numbers allow for the same side. The system also recommends the sensor installation distance. Ensure proper application of a coupling agent during installation. For optimal readings, the S signal should show more than two grid lines; if it’s less, you'll need to adjust the installation until the signal strength meets the requirement. Once properly installed, confirm the installation spacing and proceed to display the measured data. To view measurements in another unit, press the number 3 key.
3. **(OPT) Output Settings**: Select the unused channel, specify the measurement quantity, choose the unit of measurement, decide whether to save the data, and set the storage cycle.
Precautions:
1. When connecting the sensor to the host, ensure the red dots on the connector align with those on the slot. Misalignment can cause poor connectivity.
2. The measured temperature should fall within the configured range. Using a normal temperature sensor for high temperatures risks damaging the sensor due to overheating.
3. The pipe diameter should also remain within the configured limits to avoid measurement errors.
4. Always take multiple readings to ensure data accuracy. More than two readings will provide reliable results.
5. Before installing the sensor, thoroughly clean the installation area and apply a coupling agent. Stainless steel or carbon steel pipes should ideally be lightly sanded with fine-grit sandpaper before installation.
