Sichuan Vacorda instrument specializing in the production of magnetic flap level gauge, not only in the petrochemical industry, food, water treatment and other fields have attainments, but here we mainly discusses the level measurement in oil pipeline application. one of the traditional level measuring method is to use glass plate level gauge for the petroleum, chemical, heat and other industries. However, this kind of level gauge also has some limitations: When the measured medium viscosity changes or it contains more impurities, the media will cover the glass plate surface. It is inconvenience to clean up and monitoring the level of change at any time. Later, after many years of research, we have designed the UHC type magnetic level gauge, and after several years of continuous real factory operation of clients, it proved that this type of magnetic column level gauge can solve this problem.
UHC-type magnetic flap level gauge, the body material is IcrI8Ni9Ti, 316L stainless steel, and 304 stainless steel lined with PTFE anti-corrosion material and PP plastic anti-corrosion material, etc. It has a higher anti-corrosion properties. It can be said that, for most of the corrosive media on the market, you can find the corresponding anti-corrosion material in magnetic level gauge produced by Sichuan Vacorda Instruments Manufacturing Co., Ltd. What’s more, the dial display section does not touch the measured media, both waterproof and dustproof, it is more suitable for monitoring the level of the liquid that doesn’t be allowed to leak in flammable, explosive, toxic, perishable environments.
Based on buoyancy and magnetic coupling principle, the magnetic ball in the body of the level gauge is up or down with the liquid level changing and makes dual-colored turning to show the level of medium. Each cylinder is with two-color axisymmetric structures. The distance of two cylinders is 10mm. Red side of display cylinder indicates liquid and white side display cylinder indicates air. Besides measuring liquid level,it also could measure the interface of the two kinds of liquid.
It has the following features:
- The structure is simple and firm.
- Large scale bar for easy reading.
- Indicating part and measurement part is sealed and isolated, not easy to leak, easy maintenance.
- Suitable for extremely adverse operating conditions and environmental conditions.
- High temperature, low temperature resistance, high pressure, corrosion resistance.
Its main technical parameters are:
- Measuring Range: 0 - 6000 mm.
- Working Pressure: Up to 42 MPa.
- Operating Temperature:-190 ℃~425℃.
- Measurement Accuracy: 0.5%.
In October 2000, we put the anti-corrosion type magnetic flap level gauge in to use, after few years of practical application, we summarize and analysis it has two advantages：First, once put into operation this instrument, except doing some daily surface maintenance, it has no other special maintenance; second advantage is that the duty personnel do not have to go close to the level gauge, or climb to the tank, more than 10 meters away from it can be seen to the liquid level display.
