Abstract
The low solid concentrations in solutions are discovered and measured based on measurement the attenuation that occurs with a wave propagating through a fluid. Currently methods (Pitch-Catch, Pulse-echo and Immersion method) have some of weak points related with range of detection and power consumption, therefore, to increase the measuring range to include the detection of very low concentrations in solution as well as not relying on the material that the container is made of, a new technique for the pulser was designed to overcome the disadvantages of the three currently methods. This technique has been thoroughly applied to dispensing with the use of a container or reflector with a high reflection coefficient and Expanding the measuring range to include very low concentrations. The new technique demonstrates the system’s ability to distinguish the presence of particles in a fluid at a concentration lower than 10 %, which is below the limit of detection of the current method with the same device settings.
