Magnetic Float Level Transmitter

Magnetic Float Level Transmitter uses the magnetic inside of the floating ball following as the change of liquid level to change divider circuit composed by the resistor inside of the rod and the magnetic reed switch, thus converted into divider signal which can be turned by the transmitter into a standard industrial signal of 4~20mA so as to test the liquid level.

The smaller the clearance of the magnetic reed switch is, the higher the accuracy is. This level indicator can also be used for long-distance indication if combined with another secondary instrument. It is a reliable indicator with a simple principle.

◆Plastic material such as PP, PVC, NBR, PVDF, can be used in strong acid and alkaline places;

◆ Metal material such as SUS 304/316L, can be used in the place where the high temperature is up to 200 °C and high pressure is up to 64kg/cm2;

◆Metal floating ball has dimensions of Φ45, Φ52, Φ75, and so on;

◆Plastic has Φ48 and Φ55. The specific gravity ranges from 0.5 to 0.8g/cm3.

◆Output two-wire system: 4~20mA or Resistor three-wire, the supply voltage is 5~30VDC;

◆Junction box: Stainless steel, aluminum alloy, PC, PP

◆The connection has thread types like PT, PF, NPT, BSP; flange types such as JIS, DIN, ANSI, and so on available

◆ The protection level of the outgoing line or junction box is IP-65.

◆ Special specifications can be customized according to the user’s requirements.

 

When users select Continuous Float Level Transmitter, please refer to the following five steps in selection instruction. The Continuous Float Level Transmitter is a kind of customized product. To make the user easily select the right model, various types of flanges, threads, bracks, floating ball specifications, junction boxes, and material properties are specially sorted out. The user can make a selection in the corresponding model selection table.

Model Selection Magnetic Float Level Measurement

Notes:

Users select the corresponding specification of the float according to the working temperature, pressure, gravity, acid, and alkali, etc. properties of the tested liquid.

◆Temperature: the maximum temperature of PVC is 150 °C, the maximum temperature of PP is 80°C, the maximum temperature of PVDF is 150°C, the maximum temperature of SUS 304/316L floating ball is 200°C.

◆Pressure: the maximum pressure resistance of a plastic floating ball is 5kg/cm2, the maximum pressure resistance of a SUS floating ball is 40kg/cm2

◆Viscosity: for viscous liquid, it is better to choose float with a big diameter and small gravity to overcome the surface tension.

◆Acid and alkali characteristics: polypropylene is suitable for strong acid and alkali occasions while choosing PVDF in strong acid and alkali occasions of above 80℃ temperature.

◆Alcohol and oil etc: it is suggested to use stainless SUS, and use food-grade of SUS316L in the food industry.

◆Gravity: float’s gravity S.G. should be less than tested liquid’s, otherwise the float cannot drift.
