IP65 Digital Ground Water Level Recorder Piezometer, Model Name/Number:GWLR-AT-01

Next Sense Technologies made GWLR-01, Ground Water Level Recorder, is a data logger and submersible pressure transducer combination designed for remote monitoring and recording of water level or pore pressure data. The sensor is lowered into the well on a reinforced cable and submerged below the water. Once in place, the initial water pressure reading is synced with the current water level. The unit then monitors the water pressure for changes, and the pressure difference is converted to a change in water level. The entire unit is hermetically sealed to prevent any moisture from getting into the instruments circuitry. The instruments comes along with inbuilt memory and GPRS enabled web telemetry for remote communication of data. Optional rechargeable battery along with solar panel is also available for uninterrupted power even at remote places.

The GWLR-01 is used for measuring water levels in bore wells, dams, open channels and lakes.

The aim of Next Sense is to improve the current technologies offered by an organization or to develop innovations that strengthen the organization's position in the marketplace. Next Sense is the sister company of "Engineering & Environmental Solutions" which dedicatedly concentrates on research and development and we are Original Equipment Manufacturer of sensor based instruments for customized solutions since 2016. Our measurements comprised of precision and accuracy, which convinces overall Indian customers with high precised instruments and innovative-customized solutions for creating a sustainable tomorrow.

Milestones we've reached in a short span is the telemetry technique to monitor the devices remotely. As IOT emerging at vary fast pace. According to a certain report, by 2020 we will be having around 300 billion of sensors throughout the world which will be used in many aspects of our daily life. To work with this huge network of sensors, reliable technology to handle this includes Big Data, more reliable wireless networks, etc. Furthermore, block chain could be used as the future technology to contribute on this, which can provide a better, stronger and reliable network.

We specialize in rugged, low-power systems for long-term, stand-alone monitoring and control. You will also find R & D division with really forward-looking engineers, innovative engineering and technological breakthroughs in our organization.
