APLISENS
Aplisens - SGE-25 Smart Level Sensor
Hydrostatic
The SGE-25 hydrostatic level probe measures liquid levels in tanks, deep wells or piezometers. Â Its specialised design means it can measure water levels in very narrow conditions.
Â
Its operation is based on a simple relationship between the height of the liquid column and the resulting hydrostatic pressure. Â Applications include pumping stations, fermentation chambers, settling tanks, borehole levels and ponds.
Â
When the probe is lowered to the reference level it can either hang freely or lie on the bottom. Â If there is a possibility of turbulence in the tank (for example mixer operation or a turbulent inflow) then the probe should be installed inside a screening tube (e.g. made of PVC). Â Cleaning the probe diaphragm by mechanical means is strictly prohibited. Â The SGE-25 uses HART protocol and can be configured using the following metrological parameters:
Â
- Units of pressure
- Start and end-points of the set range
- Damping time constant
- Invert the output signal (.i.e. 20-4mA)
Â
Â
Through the data interchange with the probe you can also:
Â
- Identify the probe
- Read the hydrostatic pressure value, output current and percentage of measuring range
Â
Options include Exia, thread on cable entry, titanium wetted parts, DNV approval, cable options and higher temperature rating.
