Description
Technical field:
The present invention relates to a kind of fluid level gauge, particularly a kind of elastic proportional liquid level meter that is applied to HS type peculiar to vessel.
Background technology:
From shipbuilding industry, at present, China is third place in the world shipbuilding big country, riverine, the coastal large and medium-sized shipyard of hundreds of families that distributed, produce the above boats and ships of thousands of tons every year, along with the fast development of shipbuilding industry, China estimates will become the first in the world shipbuilding big country in 5 years, this just provides bigger opportunity to develop for the supporting industry of boats and ships, and liquid level gauge is about all need be with 30 on every ton ship.At present, the content gauge that uses on the boats and ships has: glass tubular type content gauge, sheet glass content gauge, magnetic level table and float level table, as follows respectively:
A, glass tubular type content gauge: this product is to adopt glass tube to make visor to observe the interior liquid level of liquid storage bin, because glass tube intensity is low, easily broken, measured medium easily flows out, and causes hidden danger, so generally only be used for water tank, is not useable for fuel tank.
B, sheet glass content gauge: this product strength is better than the tubular type content gauge, but volume is big, bodily form heaviness, and processing difficulties, after sheet glass uses a period of time, the measured medium fouling, transparency is low.
C, magnetic level table: this product is stainless steel and high-quality magnetic materials production, the manufacturing cost height, because the action of a magnetic field, liquid level shows error.
D, float-type content gauge: this product materials is many, and volume is big, and difficulty is installed.
These several content gauges all are communicated with measured medium, and their length is all close with liquid storage bin height, thereby bulky, in order to show bin liquid storage amount, usually also at content gauge side setting height(from bottom) chi and volume chi.
The Ship Design personnel are usually because of the too crowded anxiety in narrow cabin, use needs in order to adapt to boats and ships, Japan a company once developed a kind of dial type liquid level gauge, its principle is: according to pascal's principle the principle of measured medium inside is sensed on the dial plate by kapillary (silicone oil is filled in inside) and show, because silicone oil is volatile, ends in failure at last.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide that a kind of security performance is good, volume is little, the big reading of range is accurate, multiple functional, the HS type ship elastic proportional liquid level meter of robotization control, specious, easy for installation, dependable performance.
