Application Cautions for Variable Area Flow Meters
|
Application Cautions for Variable Area Flow Meters Do not apply variable area flow meters to fluids that are opaque, dirty, or prone to coat the metering tube or float, because these may render the flow meter inoperable. Be sure to install variable area flow meters with floats in the vertical orientation because their operation is dependent upon gravity. Variable area flow meters that require upward flow may not suitable in many applications where the fluid flows using only gravity. A potential safety hazard can be created if a glass metering tube breaks, especially when dangerous fluids are present in the flow meter. Be careful to install variable area flow meters with glass metering tubes in locations where the glass cannot be damaged. Also, the float can get stuck when flow turns on suddenly or when high flow rates cause the float to be reach its highest mechanical position. |
