Oil level gauge calibration device

Abstract

The oil level meter calibration device comprises a magnetostriction liquid level meter, a double-channel digital display instrument and a barrel, the two ends of the barrel are open, a strip-shaped groove penetrating through the side wall of the barrel is formed in the middle of one side of the barrel, and a straight steel ruler is arranged below the strip-shaped groove; a plurality of C-shaped elastic buckles are installed on the outer wall of the side, opposite to the strip-shaped groove, of the barrel in the length direction of the barrel, the probe rod is clamped in the elastic buckles, one end of the probe rod is a meter head, the floating ball is sleeved with the barrel, a handle is fixedly connected to the side, close to the strip-shaped groove, of the floating ball, and the handle extends out of the strip-shaped groove. A pointer is further installed at the bottom of the side, close to the gauge head, of the handle, a plurality of fixing buckles are evenly distributed on the top of the barrel in the length direction of the barrel, and the double-channel digital display instrument is connected with the gauge head and the piece to be tested. The device is simple in structure and reasonable in design, the remote transmission part of the magnetic flap liquid level meter can be effectively verified, the magnetic flap liquid level meter does not need to be disassembled, and normal work of the storage tank is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of oil level gauge inspection, and in particular relates to an oil level gauge calibration device. Background technique [0002] Due to the low resolution of the magnetic flap level gauge, it is usually equipped with a reed switch level gauge as a remote instrument when used. When we detect the magnetic flap level gauge, we usually need to use the magnetic flap The liquid level gauge can only be tested after being disassembled as a whole. If there is no valve at the connection between the storage tank and the magnetic flap level gauge, it is necessary to drain all the liquid in the storage tank and then disassemble it, so that the storage tank is in a shutdown state. affected normal production. [0003] At present, the calibration of the magnetic flap liquid level gauge is performed as a whole, and the overall detection requires the disassembly of the magnetic flap liquid level gauge, which affects the norm...
