PROBLEM TO BE SOLVED: To provide a microwave densitometer which can reduce an amount of microwave leaked to the outside and reduce an error in densitometry of measurement target liquid.SOLUTION: A microwave transmitter and a microwave receiver comprise first fixing members, antennas, second fixing members, penetrating holes, conductive members and connectors, respectively. The first fixing member is fixed to each opening window part in order to touch measurement target liquid. The antenna is shaped in a cylindrical form, comprises a dielectric substrate having a high dielectric constant, and is provided in a manner adjacent to the first fixing member. The second fixing member is provided in order to cover one of bottom faces of the antenna which is opposite to the other bottom face on the side of the first fixing member. The penetrating hole is formed to penetrate the antenna and the second fixing member. The conductive member is provided inside of the penetrating hole. The connector is provided to connect the second fixing member and the conductive member. |
