Abstract
Turbine and Venturi flowmeters were calibrated in both normal and superfluid helium in an apparatus designed specifically for that purpose. Simple in concept, the facility forces liquid helium from a calibrated bellows through the flowmeter. An ambient temperature stepping motor drives the welded stainless steel bellows whose capacity is 10 L. Flow rates range up to 0.35 L/s, and helium temperatures span from 1.25 K to 4.0 K. For the 9.3 mm bore turbine meter, identical meter factors are obtained for normal and superfluid helium. For the Venturi meter, discharge coefficients between 0.98 and 1.0 are obtained with normal and superfluid.
