Smartflow mechanical flowmeters are durable, vane-operated devices that provide visual indication of flow rate in many different styles and sizes. Rugged wetted parts are compatible with many process liquids.
Optional temperature and pressure gauges add functionality and flexibility to Smartflow Flowmeters. Brass quick-connect fittings are available on the smaller flowmeters to create an excellent, portable tool for determining flow and locating clogged lines.
Galvanic corrosion may occur in anodized aluminum components when installed in electrical connection with more noble metals such as copper. Use appropriate installation practices. For best performance, mechanical flowmeters should be installed in the vertical position with the flow moving forwards.
Injection molders know that a certain rate of flow is needed to achieve turbulent flow in cooling lines. This concept applies to most cooling applications using a water-based coolant
mixture. Charts below are for reference only. Turbulent Flow Rate is approximate based on Reynolds Number of 4000.
