Abstract
A microwave densitometer comprises a phase difference detecting section for detecting a phase difference between a microwave generated from a microwave generator and a microwave received by a microwave receiver, a rotation number updating section for varying a value of number of rotations 'n', a correcting section for obtaining a difference value .DELTA..THETA. indicating a difference between a true phase difference .THETA..sub.2 and a reference phase difference .THETA..sub.1 ' a signal converter for converting the difference value .DELTA..THETA. to a concentration signal an operation mode setter for setting a operation mode, and a holding circuit for holding the number of rotations 'n' and the apparent phase difference .THETA..sub.2 ' when a concentration measuring operation of the fluid to be measured is switched to a non-measuring operation in response to a change of the operation mode set to the operation mode setter.
