Abstract: PURPOSE:To make compatibility with bonding agent of resin excellent, to improve the dispersibility of magnetic powder and to improve electric characteristics by containing acrylic resin having one or more carboxylic acid at one end and having an active hydrogen group within a molecular chain in a magnetic layer. CONSTITUTION:Acrylic resin having one or more carboxylic acid at one end and having an active hydrogen group within a molecular chain is contained in a magnetic layer. In this acrylic resin, the carboxylic acid is located only at one end. Therefore, the carboxyl group at the end of the molecule is adsorbed in the surface of the particle of magnetic powder. The steric repulsion effect of the acrylic resin is generated, and the dispersibility of the magnetic power is improved. Compatibility with bonding agent of resin for the magnetic recording medium which is used in general is excellent, and the dispersibility of the magnetic powder in the magnetic layer is improved. The electromagnetic converting characteristic is improved. Furthermore, when the material is used with polyisocyanate together, the material reacts, and the rigid magnetic layer is formed. Thus the durability is improved.

SOLUTION: A three-way valve 27 is installed at the lower part of a detector 13 or in the halfway part of a pipe 12, and a fluid 2 to be measured and a fluid 2' to be measured are changed over. A container 29 which holds the fluid 2' to be measured is connected, via a pipe 28, to be branch port of the three-way valve 27. The container 29 is airtightly sealed in parts other than a ventilation pipe 30. The open air is supplied to the inside of only the container 29 via the ventilation pipe 30. As a result, the open-air opened face of the container 29 becomes the lower end 52 of the ventilation pipe 30 irrespective of the position of a water level 51. When the container 29 is used, even the fluid, to be measured, in a small quantity can be measured simply and at a constant flow rate, and its off-line interrupt measurement is performed easily.  Then, when the container 29 is held by a turbidity meter body in such a way that the position of the lower end 52 is identical to the water level 10 of a degassing tank 7, the desired fluid 2' to be measured can be selected easily by changing over the three- way valve 27, and an identical flow rate can be kept. As a result, the interrupt measurement can be performed with identical accuracy.
