The glass coating of the MicroWire makes it suitable for almost any environment, including industrial gases, acids, and other hazardous substances. One of its key advantages is its passive operation, meaning no electrical contacts are required. This eliminates the risk of igniting explosive gases in case of sensor malfunction, as no electric charge is generated. While measuring flow, additional data such as total volume, level, velocity, and temperature can also be obtained.
RVmagnetics' MicroWire sensor can measure the flow of various liquids and gases. Due to its small size and biocompatibility, it even enables continuous monitoring of human blood flow. Additionally, its passive nature allows for spark-free flow sensing in the oil and gas industries.
A paddle wheel is one of the most basic and reliable solutions for flow measurement. However, conventional paddle wheel sensors only detect the presence of flow without evaluating any physical quantities. By integrating a MicroWire sensor onto one of the paddles, its capabilities expand significantly. For example, revolutions per minute (RPM) can be measured, which directly correlates to flow volume estimation. Adding a thermally dependent MicroWire to another paddle enables temperature measurement of the flowing liquid or gas. Since paddle wheels are sensitive to weight balance, the lightweight MicroWire does not affect their functionality. Additionally, the data acquisition device can be placed externally, up to 5-6cm from the pipe.
The MicroWire sensor not only detects flow but also processes data into physical quantities such as volume and velocity. If precise measurements are unnecessary, it can function as a digital sensor, simply indicating the presence of flow. With a specialized placement of a single MicroWire, even flow direction measurement is possible. Moreover, commercial flow meters can be enhanced with MicroWire sensors to provide additional data, such as temperature-dependent flow analysis.
Non-invasive flow sensing with Seamless Integration & Chemical Resistance
Flow bends the MicroWire toward the sensing head, causing a change in its magnetic response. The sensor operates without direct contact with the sensing head. The system detects this change, processes it electronically, and transmits the data via Bluetooth. A custom app displays the airflow representation in real time.
