Water Level Station for Water Level (+/- 0.5% of full scale), Conductivity and Temperature - IC-SNiP-HPT-SL

The SNiP-HPT is a 'Sensor Node Integrated Package' for LoRa, LoRaWAN, FSK or CAT-M1 communication of real-time water levels, electrical conductivity and temperature measurements for continuous environmental water monitoring, in both ground water and surface water.

The base SNiP-HPT integrates 1x S-NODE and 1x Hydros-21 Sensor to a site's unique network, communication and power requirements. The S-NODE can support an added 3x Sensors. The Hydros-21 Sensor has been designed to measure water levels, Electrical Conductivity and Temperature.

Applications:

- Aquifer recharge and recovery.
- Saltwater intrusion, desalination, and wastewater.
- Wetland monitoring.
- Groundwater contamination monitoring.
- Surface water monitoring.

Advantages:

- Robust marine-grade epoxy overmould to resist corrosion in tough environments.
- Compact 3.4 cm diameter sensor body to fit into tight spaces.
- External logger with remote transmission option to deliver data to your desktop.
- Permanent connection allows you to collect data continuously without pulling up the sensor.
- Low per-sensor cost.

HYDROS 21 Water Level Sensor

The Meter HYDROS 21 sensor is a low cost, accurate tool for monitoring of water level, electrical conductivity, and temperature in both ground water and surface water. The sensor utilises a vented pressure transducer to obtain accurate water level measurements from 0 to 10m while removing the effects of barometric pressure. With a range of 0 to 120 dS/m, the HYDROS 21 sensor has the ability to make accurate electrical conductivity measurements in a broad range of applications.
