The JIYI flow meter is a device used to measure the flow rate of a liquid in a pipeline. It is designed to be accurate and reliable, making it a valuable tool for various industries such as agriculture, water treatment, and oil and gas. The JIYI flow meter is easy to install and provides real-time flow data, allowing for efficient and effective management of liquid resources

Note: This isn’t a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure and sensor orientation. It will need careful calibration if better than 10% precision is required.
