UHF magnetic flap level indicator

UHF magnetic flap level indicator
Product Detailed
1.used for measuring liquids in open and pressure vessel 2.316 SS materail can stay with high temperature / pressure ,corrosive

 

Product introduction:

 

 

 

UHF magnetic float level gauge is design according to Q/XY001-2009standard, and in compliance with HG/T 2742-1995,

UHF level gauge not only upgrade product tradition glass tube,flap level gauge, and also possess a function that glass tube, flap level gauge could not bring out, e.g. switch and analog output. With feature of visually display, ease to install, The product line UHF is used wherever fluid level has to be monitored, indicated, and controlled in a reliable way, especially with corrosive, toxic and inflammable fluids. Level indicators offer a reliable, accident-free and maintenance free usage, through simple and break-resistant construction at a maximum process pressure of 64 bar and a temperature range from –40°C through 350 °C.

 

 

  

Application:

 

UHF series magnetic float level meter are widely used for measuring liquid in open or pressure vessels. It applies to display the liquid level in the buried tank, be fit for the level, industry-bit measurement of containers of liquid medium.

if matches with transducer can output remote transmission singnal. Suitable for tall and overhead tanks of non pressurized chemical storage tanks.

1.) Indicating the fluid level

2.) Monitoring the level with alarm contacts

3.) Transferring the level using measurement value sensors (analogue signal 4-20 mA) to electrical display units

 

Function principle:

 

A float chamber is connected to the tank, and following the law of communicating tubes, the level in the float chamber is equal to the level of the tank. The float (3) follows the fluid level and transmits its mo movements contact-free to the indication rail (4) mounted on the outside. The float has a special magnet, which rotates the wafers by 180° as it passes them. The result is a clearly defined level indication, with the level shown in a continuous red stripe strongly contrasted to the white above. At increasing levels the color of the wafer changes from white to red and vice versa.

 

The indication rail and the wafers are made of ABS so that there will never be a problem of corrosion in humid and aggressive atmosphere. Each wafer has a permanent magnet, that is why the indicator is shock proof.

 

All models are available with electronic alarms, that can be mounted at any position during operation of the system, which renders possible an optimal definition of the min. and max. data points.

 

Advantages:

 

No risk of glass breakage as a result of the separation of the measurement and indicator areas. The float principle means that changes of the density in the medium have very little influence on the indication accuracy.

 

Switches / Alarm contacts:

 

Magnetic level indicators can be equipped with an arbitrary number of switch contacts. In contrast to electric float switches, switch contacts may be installed at any position of the stand pipe. Wherever additional float chambers are needed for float switches, magnetically controlled level gauges offer a considerable price benefit.

Electrical level measurement transducers which use the displacement principle must be recalibrated each time the fluid density has changed. The price of a magnetically controlled level indicator with integral electrical measurement transducer is considerably lower than level measurement transducers. The reed chain with an R/I measurement transducer can be changed without interrupting the operation. The measurement chamber is hermetically sealed – there is no contact between the fluid chamber and the reed chain.

The switches / alarm contacts are secured with pipe clips, and can be adjusted to any desired height. The connection is using 3 or 2-core cable or casing terminals. The changeover contact can be used as opener or closer. The switches are also available as explosion proof version.

 

Floats:

 

The construction of the float requires a great amount of technical knowledge. The float with its special magnet can rotate freely in the float chamber.

The float materials are stainless steel, 304,316, or U-PVC, PP, . Floats are used from a minimum density of 0,35 kg/dm³. all of the floats are sealed.

 

Indication rail:

 

The UHF level gauges can be supplied with indication rails made from 2 different materials. ABS indication rails are resistible to breakage. The max. permissible media temperature is 80°C, with 20°C ambient temperature and natural convection as test conditions.

Aluminum indication rails can be supplied as one part rail up to a length of 5 m. The sight cover material depends on the temperature, up to 150°C the material is ABS and up to 400°C it is glass.
