Electronet’s series FL-700 PTC is micro-controller based temperature pressure compensated flow indicator totaliser designed for various industrial applications. These can be used for indication & tantalization of flow. Theses three individual inputs can be provided for flow, temperature & pressure. The built-in battery back-up is provided for the memory to avoid loss of data in case of power failure. The micro-controller based design provides full flexibility for flow metering applications.
