The rotameter is the most popular variable area flow meter because of its low cost, simplicity, low pressure drop, relatively wide rangeability and linear output. Furthermore, it operates simply: in ...

Differential pressure mass flow meter (s) find application anywhere it can be safely assumed the fluid has reliable viscosity, and preferably where temperature does not change. Compressibility of ...

Titan Enterprises has developed and is supplying a high pressure version of its 900 Series turbine flow meter for measuring refrigerant flow. Adapted with steel reinforced polymer components, to give ...

Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris. Being able … ...

These meters are highly accurate, typically 0.5% of flow rate over a dynamic range up to 300:1. But to maintain their accuracy, they must have a flow rate above 1.5 fps.
