Abstract

The invention provides an axial outer clamping type sensing device which is installed in a pipeline and used for detecting fluid flow in the pipeline. The axial outer clamping type sensing device comprises a first installation pipe, a second installation pipe, a connecting pipe, a first ultrasonic probe and a second ultrasonic probe, the first installation pipe and the second installation pipe are respectively installed on the pipeline and respectively communicated with two ends of the connecting pipe, the first ultrasonic probe is installed on the first installation pipe, the second ultrasonic probe is installed on the second installation pipe and arranged corresponding to the first ultrasonic probe, and a connecting line between the first ultrasonic probe and the second ultrasonic probe is coincided with the axis of the connecting pipe.

Description

technical field [0001] The invention relates to an axially outward clamping sensor device. Background technique [0002] In the prior art, the fluid flow inside the pipe is usually detected by setting an ultrasonic probe. Existing ultrasonic probes are usually used to detect the flow rate of pipe fittings using an external clamp type ultrasonic probe, that is, the corresponding ultrasonic probe for transmitting and receiving ultrasonic waves is clamped on the pipe fitting to be tested, and the ultrasonic probe is inclined relative to the axial direction of the pipe fitting. During the detection process, the ultrasonic wave is sent and received through the piezoelectric chip set in the ultrasonic probe, and the fluid flow in the pipe is detected. However, this method has the following disadvantages: it is not conducive to measuring small-diameter pipes; the measurement sound path is short; the measurement accuracy is low; it is greatly affected by temperature changes. Cont...
