Product Overview: The Malema Flow Sensor (Model: M-VF-S11-000) is a genuine original factory product, independently developed and manufactured by Malema (USA), a professional leader in industrial flow measurement equipment. Adhering to Malema's strict international manufacturing standards, advanced flow detection technology and rigorous quality control system, this sensor is a high-reliability, high-precision core component designed for industrial fluid flow measurement scenarios. As a key product in Malema's flow sensor series, it is mainly used for real-time detection, data collection and accurate transmission of fluid flow, ensuring the stable, efficient and precise operation of the entire fluid control and measurement system. Widely applicable to industrial pipeline flow monitoring, fluid process control, chemical medium measurement, water treatment and other industrial scenarios requiring high-precision flow detection, it features excellent anti-interference ability, stable performance, easy installation and maintenance, and long service life, effectively improving the measurement accuracy and operational stability of industrial fluid systems. All parameters are strictly calibrated by the original factory, consistent with Malema's official technical specifications, without any manual modification[1]. Note: "M-VF" in the model refers to "Malema Variable Flow", indicating the product's variable flow measurement function; "S11" is the series code, and "000" is the standard configuration code. This product is 100%原装 (Genuine Original) from Malema USA, complying with relevant American and international industrial measurement standards[2].
