Anti-interference detection equipment for ultrasonic gas meter

Abstract

The invention discloses ultrasonic gas meter anti-interference detection equipment, and relates to the technical field of ultrasonic gas meters. The ultrasonic gas meter anti-interference detection equipment comprises a rack, a detection piece installed on the rack, a lifting plate and a lifting driving piece, wherein the lifting driving piece comprises a driving motor and a lead screw, the output end of the driving motor is in transmission connection with one end of the lead screw, the other end of the lead screw is rotationally connected to the rack, the lead screw penetrates through the lifting plate and is connected with a lifting plate lead screw nut pair, the detection piece comprises a first connecting port, a second connecting port and high-pressure gas supply equipment, the first connecting port and the second connecting port are matched with the gas inlet and the gas outlet of an ultrasonic gas meter respectively, the other end of the first connecting port is connected with the high-pressure gas supply equipment, a limiting piece is arranged on the lifting plate, the limiting piece comprises two limiting blocks of an L-shaped structure, electromagnets are fixedly connected to the bottoms of the limiting blocks, and a center point is marked at the center of the top of the lifting plate. The ultrasonic gas meter anti-interference detection equipment has the advantages of being high in detection precision, high in working efficiency and high in intelligent degree.

Description

technical field [0001] The invention relates to the technical field of ultrasonic gas meters, and more specifically relates to anti-interference detection equipment for ultrasonic gas meters. Background technique [0002] As a clean, efficient and high-quality energy, natural gas has become the first choice of domestic energy structure. With the widespread use of natural gas, it is particularly important how to achieve fair measurement as a gas meter used by urban natural gas users for trade measurement. With the construction and popularization of gas transmission pipelines, gas meters have sprung up like mushrooms after rain, from mechanical to electronic, from traditional membrane meters to fully electronic ultrasonic gas meters, new concepts and technologies are constantly emerging, and various flowmeters The accuracy and scope of use are also constantly improving. Due to its advanced technology and easy intelligence, ultrasonic meters are gradually moving from the indus...
