In open cast mining, the groundwater levels must be continuously reduced to protect the mining area from flooding and the excavation walls from instability due to water pressure. A large number of dewatering wells with submersible pumps are kept in operation for this purpose. A continuous water flow prevents the pump shaft from blocking due to the effects of hardening clay/iron oxide deposits. To regulate the pump output, precise level measurement is required in each of the up to 750 m deep wells.
Maximum measurement reliability
Long-term availability of the measuring sensor
Maintenance-free, thanks to self-cleaning effect of the flush-mounted diaphragm
Level measurement via submersible pressure transmitter for regulation of pump Output
- Reliable, maintenance-free measurement
- Measurement reduces pump operating costs through output control
- Abrasion resistant CERTEC® ceramic measuring cell
