Hydrostatic: Differencial pressure
Continuous level measurement in liquids in closed pressurized tanks.
The hydrostatic pressure of the liquid column leads to a difference in pressure in closed tanks with pressure blanketing. The pressure difference, in turn, deflects the measuring element which is proportional to the hydrostatic pressure.
Especially suited to:
Liquids in closed tanks with pressure blanketing up to process temperatures of +400° C. Also in case of foam an baffles as well as abrasive and corrosive media.
- Unaffected by the medium surface
- Unaffected by tank obstacles and the tank geometry
- Condensate-resistant Contite measuring cell or ceramic cell with high chemical resistancy
- High overload resistance
- Hygienic versions
The Deltabar series measures irrespective of ambient temperatures and is unaffected by dielectric constant, foam and baffles. In addition, it provides a high degree of overload resistance.
Process temperatures -70 to +400°C (-94 to +752°F) and process pressures 5 mbar to +400 bar (0.07 to +5.800 psi).
