Abstract

PURPOSE:To discover easily cracks, strain or stain of a vessel, by passing a trasmitting element and reception element of ultrasonic waves through a wire cable together with a weight and flowing into a fluid vessel and then, moving them. CONSTITUTION:A transmitting element 3 and a reception element 4 of ultrasonic waves are fixed to a wire cable 2 by leaving a space and each weight 5 is provided between both elements. The elements 3, 4 are guided by the cable 2 and are flowed and moved while rolling over the inner wall of a pipe or a fluid vessel 1. Ultrasonic waves are produced by the element 3 and cracks of the wall face of the vessel and reflecting scattering or transmitting waves etc. caused by the substance adhered on the wall face, are detected by the element 4 and then, its signal is sent to an arithmetic circuit or a control circuit through the cable 2. Hereby, stable fluid control is carried out by monitoring always the conditions of the vessel.

。In FIG. 1, reference numeral 1 denotes a wastewater vibrator through which sewage or the like flows, and an ultrasonic wave transmitting/receiving element is inserted into the flow path therein for detection. 2 is a wire cable which also serves as the id of the element and conducts signals. Reference numeral 3 indicates a transmitting element, and reference numeral 4 indicates a receiving element, which are fixed to the wire cable 2 at intervals, and a weight 5 is provided between the two. Therefore, the transmitting/receiving element 3.4 is guided by the wire cable 2 while the weight 5

行なわせる。The detection signal of the receiving element 4 is extracted through the cable 2, amplified to a predetermined size by an amplifier, filtered by a moon filter, and digitally converted according to the detection signal by an A-D converter. The pulse signal is converted into a pulse signal with a proportional number of pulses corresponding to the signal strength, etc., and the converted pulses are processed by a computer and displayed or output as a control signal. The arithmetic processing performed by the computer makes a determination by comparing the input with a reference value or standard value, and operates a control device based on the determined output to perform work to remove dirt and the like.
