Abstract

PURPOSE: To make unnecessary the change of mechanical setting of the transmission element and reception element, by installing the transmission and reception elements opposingly in the measured solution, and using selectively the transmission element for transmission or reflection depending on the concentration of liquid and the length of measured distance.
CONSTITUTION: Taking the reception sound pressure of ultrasonic wave propagating in the suspension of distance l as ER, the reception sound pressure when the particles of suspension are zero as ERO, and the attenuation by particles of suspension as αs, αsl is shown in equation (I). When the change-over device 13 is set to a, a', the pulse transmitter 6 is driven with the transmission gate signal of the time limit setter 11 and the output signal is applied to the transmission element 1. The ultrasonic pulse from the element 1 propagates in measured solution and is received at the reception element 2 and is the output 10 in proportion to the attenuation αsl via the logarithmic amplifier 7, differential amplifier 8. Further, when the change-over device 13 is set to b, b', the ultrasonic wave pulse propagates as reception element→transmission element (reflection body)→reception element in the measured solution into the amplifier and processing is made as above. Accordingly, the change of mechanical setting of transmission and reception elements can be made unnecessary.
