Q: What are the suitable applications for this sensor?
A: It is suitable for monitoring gas flow in pneumatic systems, such as verifying the gas consumption of grippers or injectors, or detecting whether there is airflow in the gas path.
Q: What could be the reason for the measured flow rate being too high or too low?
A: This could be due to blockage or leakage in the gas path, or the sensor's accuracy (±5%) itself may not be sufficient to detect minute flow fluctuations. It is recommended to check the gas path seal and calibrate it with a standard flow meter.
Q: Can it be used directly with other brands of gas hose connectors?
A: The terminal accessory for this model is an internal threaded connector; the specific specifications are not clearly stated in the search results. Compatibility requires confirmation that the thread standards and dimensions of other brands' connectors are consistent; otherwise, an adapter may be required.
