OTT ITC - Intelligent Top Cap


Request more information or a quote
The OTT ITC (Intelligent Top Cap) is a high performance, yet compact and economical means of remote communications via GSM/SMS for the OTT Orpheus Mini, Thalimedes, and CTD instruments.


  • Addition of the OTT ITC to select OTT instruments creates a complete monitoring, data storage, and communications station in a compact and economical package
  • Configurable for any of the following:
       - SMS active transfer - automatically self-timed transfer to PC or data center
       - SMS alarm messages - alarm triggered as pre-set thresholds are achieved then sent to phone, email, or fax (Orpheus Mini only) 
       - Data on request - polling during dedicated time slots
  • Applicable in well pipes from 2” diameter
  • Power supplied by easily accessible lithium battery or external supply such as solar panel
  • Compatible with OTT Orpheus Mini Groundwater Pressure Sensor and Logger or OTT Thalimedes Shaft Encoder


  • Incredibly economical means of transforming a groundwater measuring site to a complete data transmission system, meaning infrequent trips to remote wells for data download. 
       - Once the OTT ITC and Orpheus Mini are deployed, the site may not require a visit for 2 years!
  • Complete solution: Sensor, transmission unit, receiver unit with data management and evaluation software. All the components are coordinated, which guarantees a smooth operation
  • Wireless data transmission between OTT Orpheus Mini data logger and ITC allows reference measurements without removing any of the OTT instruments. In a 4” well, even samples can be drawn without removing the instruments
  • Flexibility allows the user to choose the data transmission most appropriate for their needs – through SMS, time-slot method, or GPRS
  • Flexibility in the power supply allows the user to configure according to the site's needs – either a lithium battery or a solar power supply can be used
  • Low power draw means that the ITC can transmit data for up to two years without maintenance
  • No tools required for battery change or SIM card installation
  • Flood-protected housing improves reliability in the field - in any condition
  • Easy installation on 2', 3' and 4' well pipes without thread
