Chemistry / Petrochemistry
Chemical processes make very high demands on electronic pressure measuring instruments and hydrostatic fill level probes in two respects:
- processes may be complex with high dynamic pressures and fast changing temperatures
- the media are diverse and may be chemically aggressive, explosive, toxic, abrasive and sometimes also dirty and viscous.
Add to this top safety requirements, especially in explosion hazardous plant and equipment and the absolute demand for top operational reliability.
Applications
- Pressure monitoring of tanks for gas and fluids
- Pressure measurement in distillation columns, supply systems and vessels (e.g. ammonia, solvents)
- Fill level measurements in storage tanks for fluids or sludge
- Fill level monitoring in distillation columns and retention tanks
- Fill level measurement for coolants, condensates and end products
