Sensors

The Ontoto Data Loggers can be configured to many sensors, however over time we have sourced and tested various sensors and recommend the following sensors for their reliability and stability.

Holykell HPT604 Submersible Water Level Sensor

The Holykell HPT604 is used for water level, water pressure and hydrostatic level measurement. Based on a 316SS fully sealed stainless steel housing design, it can be immersed in liquid for more than ten years.

Application :

  • Hydrostatic level measurement
  • Water pressure level measurement
  • Deep well and groundwater monitoring
  • Sea water level measurement and control
  • Irrigation equipment
  • Level measurement in pumping station
