The B+B Sensors FLW-122 can measure gaseous flow rates from 0 - 0.1 m/s up to 0 - 100 m/s.
No, the FLW-122 is designed with no mechanical parts, which enhances its reliability and reduces maintenance requirements.
It uses a thermal principle with two platinum resistance elements. One element is heated, and the sensor measures the heat loss due to the gas flow over the sensor to calculate the flow rate.
The sensor is designed for gaseous measuring media. Its suitability for specific gases should be confirmed based on chemical compatibility and operating temperature ranges.
The sensor features very fast response times due to its thermally efficient structure and short warm-up time.
Yes, the design of the sensor enables easy analysis and calibration.
It is suitable for applications in gaseous measuring media, building automation, automotive engineering, medical engineering, device monitoring, cooling devices, and the food industry, among others.
Ensure proper electrical connections are made according to the datasheet. Verify that the sensor is correctly positioned within the gas flow path and that the gas medium is compatible. Check for any blockages or contamination on the sensor elements.
Confirm that environmental conditions (temperature, pressure) are stable or within the sensor's operating specifications. Recalibrate the sensor if it has been subjected to extreme conditions or prolonged use. Ensure the gas composition remains consistent.
Visually inspect the sensor for any physical damage. If damage is found, the sensor may need to be replaced. Refer to the warranty information or contact the manufacturer for replacement options.
Setup: The FLW-122 thermal flow sensor requires integration into a system that can interpret its output signal, typically related to the heat loss measured. Consult the product's technical datasheet for specific electrical connection requirements and recommended mounting orientations to ensure optimal performance. Proper installation in the gas stream is crucial for accurate readings.
Compatibility: This sensor is designed for gaseous measuring media. Its compatibility with specific gases should be verified based on chemical inertness and operating temperature ranges. It is commonly integrated with control systems, data loggers, or PLCs capable of processing analog or digital signals derived from the sensor's thermal output.
Care: Due to the absence of mechanical parts, routine maintenance is minimal. However, it is essential to prevent the sensor's measuring elements from accumulating dust or contaminants that could affect heat transfer. If necessary, clean the sensor carefully using a soft, dry cloth or a gentle, non-corrosive gas purge. Avoid using liquids or abrasive materials that could damage the delicate platinum elements.
