Liquid level
detection methods |
Digital controlled electric servo balancing type consisting of small size displacer, measuring wire and wire drum |
| Measuring range |
Maximu: 60m |
| Temperature |
Liquid: -200 to +300°C
Ambient: -20 to +55°C (Temperature of main body)
However, the liquid and the moisture inside the wire drum room shall not freeze over, nor adhere.
*Not suitable for the use environment where the mass of displacer changes. |
| Pressure |
Maximum: 3MPa |
| Accuracy |

Liquid level measurement
±(0.1+20·b/ρ·+0.06L)mm
| ρ: |
Density of liquid to be measured |
| A : |
Cross section area of displacer (cm2) |
| L : |
Measuring range (m) |
| b : |
Coefficient Standard ball bearing spec. (Shaft dia.Ø3) b=1,
PTFE Shaft spec. (Shaft dia.Ø3) b=2 |
|
| (2) |
Interface measurement
In case of density difference of 0.2
±(1.7·a + 0.06L)mm
| a: |
coefficient depending on interface conditions 1 to 5 |
|
| (3) |
Density measurement : ±0.01g/cm3 |
*Under reference conditions. |
