English term or phrase:rotary provers include rotary meters as transfer meters
Analysis of uncertainties of proving of
diaphragm meters at different meter shops
in Canada showed that they fall in the interval
from ±0.2% to ±0.35%. These numbers
comply with the results of regular round
robin tests where the variation between meter
shops normally is less than 0.7%. Some round
robin tests exhibit a larger variation but this
is understood because the round robin spread
includes uncertainties related to transportation
of transfer meters.
Rotary provers include rotary meters as
transfer meters. The rotary transfer meters
introduce a major component of uncertainty
to proving systems. The uncertainty of rotary
proving systems depends mostly on the uncertainty
of the chosen rotary transfer meters. For
different transfer meters, the uncertainty of
rotary proving systems may be from ±0.3%
Las pruebas de medidores rotativos incluyen a éstos como medidores para transferencia.
Explanation: Los medidores de caudal rotativos (desplazamiento positivo) tienen unos elementos internos como los de las bombas o compresores rotativos. En los primeros, los elementos internos son movidos por el fluido que miden y, en los segundos, los elementos internos son movidos por el motor. Los medidores rotativos son aceptados universalmente para medir transferencias (se entiende comerciales) porque ofrecen una muy buena exactitud.
