WebMethane concentrations measured 0.3 m (1 ft) from the roof and face of the box cut were used to estimate face airflow quantities. Fresh air flow rates of 1.89 ... (5 cfm) using a rotameter. The 5 cfm flow rate provided methane concentrations in the gallery that were easily recorded by the methane monitoring instrumentation. WebIn general, glass tube rotameters can measure flows up toa bout 60 gpm water and 200 scfh air. A correlation rotameter has a scale from which a reading is taken (Figure 1). This reading is then compared to a correlation table for a given gas or liquid to get the actual flow in engineering units.

WebWater Treatment: Rotameters are commonly used to measure water flow rate in treatment plants, where accurate flow measurement is crucial for effective treatment. Chemical Processing: In chemical processing, rotameters are used to measure the flow rate of chemicals and ensure consistent and accurate dosing of chemicals. WebThe rotameter principle of operation is a mechanical means of flow measurement. They measure flow using a float that is able to move freely up and down within the flow tube. The buoyancy force acting on the float, the flow resistance, and the weight of the float itself are all in equilibrium. north narrabeen pool facilities
