How to choose suitable float for different liquid
How to choose suitable float for different liquid?
|
Users should select suitable float according to the working temp., pressure,gravity,
|
| acid and alkali of the tested liquid. |
|
◆Temperature:
|
| PVC maximum temperature is 80°C, PP maximum temperature is 80°C, |
| PVDF maximum temperature is 150°C, |
| SUS304/316L maximum temperature is 200°C. |
| ◆Pressure: |
| plastic float maximum pressure resistance 5kg/cm2, |
| SUS304/316L maximum pressure resistance 40kg/cm2. |
|
◆Viscosity:
|
| For viscosity liquid, it is better to choose float with big diameter and small |
| gravity to overcome the surface tension of liquid. |
|
◆Acid and alkali liquid:
|
| please choose PP or PVDF, if temp. is higher than 80°C, PVDF ONLY |
| ◆Alcohol and oil etc. liquid: |
| It is suggested to use stainless SUS. |
| Please select food grade SUS316L in food field. |
| ◆Gravity: float's gravity S.G. should be less than tested liquid. |
