Features: The Water Flow Meter is a compact and easy to install meter. Its versatile designs allows for compatibility with various output modules, sensors, and remote transmitters. Designed for professionals and individuals alike, the Flow Meter is perfect for anyone who needs to accurately measure liquid flow rates. For use in various applications such as water heaters, water dispensers and more. Its compact size and easy installation make it suitable for a wide of applications. For horizontal or vertical installation, the flow direction of the fluid must be consistent with flow direction indicated by the arrows on the sensor housing. In order to avoid particles and debris entering the flow sensor, a filter must be installed at the water input of the flow sensor. The installation of the water flow sensor should avoid strong vibration and shaking environment, so as not to affect the measurement accuracy of the flow sensor. No severe impact and corrosion of substances is strictly prohibited to remove or touch the medium temperature should not exceed 80 C.
