Liquid Flow Sensor 'SLF3C-1300F'
Media detection function based on thermal conductivity! Our flow detection system, proven in the industry, has evolved further.
The "SLF3C-1300F" is a liquid flow sensor equipped with thermal conductivity functionality, allowing for detailed observation of liquids within applications. By utilizing the thermal conductivity feature, it can measure the thermal conductivity of the liquid after the flow has stopped, enabling the system to accommodate new applications and functions. Additionally, it can distinguish between "working solutions" and "cleaning solutions," ensuring that the cleaning cycle of the equipment is effective. 【Features】 ■ Concentration monitoring ■ Accuracy checks ■ Cleaning confirmation ■ Safety verification *For more details, please download the PDF or feel free to contact us.

Liquid flow monitoring in pump control - Early detection of wear, backflow, and clogging.
Pumps installed in analytical devices and laboratory equipment are important components responsible for the precise supply and injection of liquids. However, wear from long-term use, blockages in the piping, and backflow can lead to risks such as flow rate variability, measurement errors, and unexpected device shutdowns. To address these issues, sensing technology that monitors liquid flow in real-time is effective. By utilizing liquid flow sensors, preventive maintenance and condition monitoring can be achieved, including: ■ Detection of pump wear and valve vibrations - High-sensitivity detection of subtle noise and vibrations ■ Detection of backflow - Understanding reverse flow to analyze causes of efficiency decline and malfunctions ■ Early detection of blockages - Capturing flow rate decreases to reduce equipment damage and downtime For such applications, the following liquid flow sensors are recommended: ■ LG16 Series: Suitable for high-precision measurement of micro flow rates, ideal for pump control in analytical devices and laboratory equipment ■ SLF3S Series: Compact and fast-response design for quick detection of signs of wear and blockages For more details on liquid flow sensors and compatible products, please refer to the product page or catalog.
