Problems solved by technology

Since the guide column is very high (>22mm), it operates day and night all year round, the deformation of the tank wall or the settlement of the tank foundation will affect the verticality of the guide column, so the tank manufacturing structure is complex and the process requirements are high

Embodiment Construction

[0018] Such as figure 1 As shown, the 11 heads of the magnetostrictive sensor measuring rods (electronic compartment and display 10) face down, and the 6 heads of the stainless steel weight guide cylinders with hanging rings 601 welded on the ends face up, and are fixed side by side with the binding ring 7. In one piece, the π-type pulley bracket 2 inserting legs 202, 203 are inserted on the upper edge of the tank wall 12, and the base leg fastening bolts 204 are tightened, so that the pulley bracket base 201 is horizontally fixed on the upper edge of the tank wall 12. Such as figure 2 As shown, the bracket 202 is a double-tooth structure, and the inner width of the two teeth is the same as the outer diameter of the stainless steel weight guide cylinder 6 . Such as image 3 As shown, supports 8 and 9 are sleeve-type structures, adjustable in length, and the lower ends of supports 8 and 9 have strong magnets 901 fixed on the tank wall 12, 902 is a sleeve, 903 is a leg, and 9...

Abstract

The invention relates to a liquid level measuring device for a floating roof tank and a measuring method using the device, comprising a magnetostrictive liquid level sensor, a sensor hard measuring rod fixed side by side with a stainless steel guide cylinder, and a permanent magnetic ring core. It is composed of a heavy hammer and a magnetic position detection electronic warehouse, and also includes a pulley, a pulley bracket and a steel wire pulley. The pulley is installed on the tank top bracket, and the steel wire pulley passes through the pulley on the bracket. On the floating roof of the top tank, put the heavy hammer with the permanent magnetic ring core on the other end into the heavy hammer guide cylinder, so that the pull rope is in a tight state.

Description

technical field [0001] The invention relates to a liquid level measuring device for a floating roof tank and a measuring method using the device. Background technique [0002] Floating roof tanks are mostly used for product oil storage, and their volume is large (for example: volume of 50,000 m 3 Tank, diameter 60m, height 22m; volume 100,000m 3 The tank has a diameter of 80m and a height of 22m. ), because it is used for refined oil storage, it requires high measurement accuracy and resolution of liquid level. [0003] In the prior art, radar liquid level gauges are mostly used for liquid level measurement of floating roof tanks. In practical applications, radar liquid level gauges are installed on the top of the hollow guide column of the floating roof, and the guide column is fixed on the tank wall. In order to keep the liquid in the guide column The level is consistent with the liquid level of the tank, and a series of holes are evenly opened on the wall of the guide ...
