Description

Technical Field

[0001] This utility model relates to the field of metering instrument installation equipment, specifically to a sleeve for installing a material metering instrument in a spherical tank. Background Technology

[0002] Currently, spherical storage tanks are widely used in the petrochemical and energy equipment fields in China. The storage medium shell is divided into liquid and gas, with most spherical storage tanks storing liquid. The storage medium in the tank is mostly liquid. Servo level gauges are used to measure the amount of medium in the tank. To avoid the impact of liquid entering and leaving the liquid on the liquid level during installation, a waveguide is required for the servo level gauge. The bottom of the existing waveguide is usually fixed by multi-point bolt clamping, which is a complicated installation process. If the bolts are tightened too much, the waveguide is prone to deformation. Utility Model Content
