Application Description
In a new mass flowmeter, three Vespel® polyimide coil bobbins play a key role in accurate measurement of the flow of process fluids. The bobbins are used for a driver coil and two sensor coils. The instrument, a Model m300 3-in. (76-mm) mass flowmeter from Schlumberger, is engineered for many applications in oil, petrochemical, food processing, pharmaceutical and other demanding industries.
Benefits Gained
Aids accuracy. The excellent dimensional stability of the Vespel® parts helps assure accurate measurements over a wide range of temperature and humidity conditions.
Resists high temperatures. Vespel® parts can serve at temperatures far above Schlumberger’s current maximum service rating of 400°F (204°C) for the flowmeter.
Fights stress. Thanks to their toughness and strength, the Vespel® bobbin parts withstand the stresses imposed by handling and winding.
Materials Selected and Why
Vespel® parts meet demanding requirements for temperature resistance, toughness, strength and dimensional stability.
