Description

Portable ultrasonic flowmeter

Technical Field

The utility model relates to a check out test set specifically is a portable ultrasonic flowmeter.

Background

The ultrasonic flowmeter adopts the time difference type measuring principle that a signal transmitted by one probe penetrates through a pipe wall, a medium and the pipe wall on the other side and is received by the other probe, meanwhile, a signal transmitted by the second probe is received by the first probe, a time difference delta t exists between the two probes due to the influence of the flow velocity of the medium, and the conversion relation V between the flow velocity V and the time difference delta t is calculated to be (C2/2L) × delta t, so that the flow value Q can be obtained.

At present, common ultrasonic flow meters on the market are mostly plug-in type, namely, the common ultrasonic flow meters are inserted into a pipe body to be measured or are installed on the outer wall of the pipe body to be measured. However, most of the existing devices are fixed on the pipe body through screws or fixing pieces, so that workers cannot rapidly detach the device after the measurement is finished, the working efficiency is greatly reduced, and therefore the portable ultrasonic flowmeter is provided.
