  • 706 Extra High Pressure Coriolis meters accommodate up to 300MPa

抄録

In order to correspond to the regulations on the exhaust gas from diesel engines which becoming increasingly strict, fuel injector makers have been earnestly engaged in the development of super high pressure injections and multiple phase injections. To improve the combustion even better, exact understanding of the injector's characteristic which decides the accuracy of the injection is "must". By using a high-strength Co-Ni alloy for the measuring tube material and making the shape an oblong dual loop with no weld on the wet part, we have enabled the super high pressure (200 to 300MPa) and extra low mass flow measurement at the injector inlet, which had been asked for years but never been achieved, with our new type Coriolis Flowmeter. The technology and expected developments are explained in the following.
