PROBLEM TO BE SOLVED: To easily and inexpensively correspond to various flange standards.SOLUTION: A microwave densitometer transmits a microwave from a transmission antenna and finds out density of a measuring object included in a measuring object fluid from a propagation characteristic of the microwave propagated to the measuring object fluid located between the transmission antenna and a receiving antenna. An external shape of the microwave densitometer, when a seal surface is abutted on each flange joint of a pipe through a gasket and the microwave densitometer is installed by putting the densitometer between a pair of flange joints, is regulated so as not to interfere with a plurality of through-bolts penetrated through bolt through holes of the flange joints. |
