32-bit microprocessor with 16 MB of memory for 1,120,000 readings
Virtually maintenance free:
A battery change is not necessary, and so ongoing operating costs are not incurred.
Installation using 1" tube diameter (probe)
For each measuring task - a suitable measurement routine: single value measurement, average value measurement, event control (swelling mode, Delta Mode), flow calculation (W/Q table, polynomial).
Accurate and reliable:
- Water level: 0.05 % Measurement accuracy (= 1 cm at 20 m measuring range)
- A wide selection of ceramic capacitive pressure transducers from 0.2 bar to 30 bar
- Temperature: 0.3 °C (standard), 0.1 °C (optional)
Stainless steel housing 1.4404 (standard) and 1.4539 (option); can also be used under extreme environmental conditions (landfills, contaminated sites, brackish water etc.)
2-step, permanent flood protection up to 3 m water column
Two clever APPs are available for configuration and data read-out of the Dipper-PT. Operating software for beginners SEBAConfig (Windows) a user-friendly interface (Wizard) for various routine tasks. SEBAConfigApp (Android, iOS) and BlueCon 2 (Bluetooth® module) can be conveniently combined for configuration and data collection of Dipper-PT via Bluetooth® with a smartphone or tablet.
The data transmission module SlimCom can be combined with Dipper-PT to transmit the data directly to your workstation. For measuring tasks with short recording intervals starting from 1 second (e.g. for pumping tests) the use of an external power pack module is recommended.
