Abstract

The invention discloses a bi-directional self-circulation liquid indicator detection device, which comprises a main tank and a branch tank. Emptying pipes with valves are connected with water outlets of the main tank and the branch tank respectively, the interior of the main tank is communicated with the interior of the branch tank through a pipeline controlling component, and by means of the pipeline controlling component, detecting liquid in the main tank can be transported into the branch tank or detecting liquid in the branch tank can be transported into the main tank. A mounting rack on which top-mounted liquid indicators are installed is arranged on the top of the main tank, and a position adjusting mechanism used for adjusting the vertical position of the mounting rack is arranged between the mounting rack and the main tank. A transparent glass tube and a mounting tube with a valve which are communicated with the interior of the main tank are vertically arranged at the outer side of the main tank, a scale used for reading the liquid level in the transparent glass tube is arranged at the outer side of the transparent glass tube, and a connection flange on which lateral-mounted liquid indicators are installed is arranged at the opening of the mounting tube. The bi-directional self-circulation liquid indicator detection device has the advantages of being low in water consumption, easy to operate and wide in application range.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to a verification device for a bidirectional self-circulating liquid level gauge. Background technique [0002] Liquid level gauges are measuring instruments used to indicate and control liquid levels in industrial process measurement and control systems, and are widely used in petroleum, chemical, pharmaceutical, metallurgy, electric power and other fields. Liquid level gauges can be divided into top-mounted liquid level gauges and side-mounted liquid level gauges according to the actual installation position. The top-mounted liquid level gauges include input liquid level gauges, ultrasonic liquid level gauges, and radar level gauges And float type liquid level gauge, etc., side mounted liquid level gauge includes magnetic flap liquid level gauge and differential pressure liquid level gauge, etc. As an important measuring instrument, the measurement accuracy of the liquid leve...
