Latest Patents

Nawa's latest patents include a physical quantity measurement device that features a secondary flow path designed to connect an upstream opening to a downstream opening. This secondary flow path is positioned gravitationally below a primary flow path. Ultrasonic transducers are strategically placed to project into the flow within the multilayer unit. This configuration effectively prevents the entry of water droplets into the ultrasonic propagation path and minimizes the adhesion of droplets to the transducers. As a result, the device can accurately measure the flow rate of fluids, even when they contain water droplets. Another notable patent describes a physical quantity measurement device capable of measuring components in a fluid, even when it contains fine droplets. This device includes an inflow direction regulator at the inlet opening of a sub-channel, which is designed to guide the flow direction at a predetermined angle.
