| 摘要 |
The purpose of the present invention is to provide a device for measuring a concentration, capable of measuring a concentration of slurry which is actually sprayed from a nozzle in a wet blast processing device. The device for measuring a concentration comprises a concentration measurement container, an emission part, an opening/closing member, an introduction member and a connection member. A nozzle may be connected to the connection member. A high gas-liquid three phase material including slurry sprayed from the nozzle passes through the introduction member and the opening/closing member to be introduced into the concentration measurement container. A concentration of the slurry sprayed from the nozzle can be calculated by measuring and operating at least either a mass or a volume of the slurry collected in the concentration measurement container.
