DWLR (Digital Water Level Recorder) Piezometer:
A DWLR Piezometer is a specialized instrument used for monitoring groundwater levels. It combines the functionality of traditional piezometers with modern digital recording capabilities.
These piezometers are particularly relevant for borewells, wells, and reservoirs where accurate water level data is crucial.
Here are some key features of DWLR Piezometers:
IP 68 Sensor: The sensor is protected against dust and water ingress.
IP 66 Display Enclosure: The display unit is also well-protected.
Inbuilt Telemetry System: Some models come with telemetry for remote data transmission.
Universal Power Supply: They can operate on a wide range of power inputs (85-300 VAC or 24 VDC).
Customizable Cable Length: The cable length can be adjusted as per the specific requirements.
These piezometers play a crucial role in monitoring groundwater levels, especially in compliance with regulations set by the Central Ground Water Authority (CGWA) .
How They Work:
A piezometer consists of a casing, a filter, and a water level sensor (also known as a transducer).
The water level sensor measures the pressure exerted by groundwater at a specific point in the ground and converts it into an electrical signal.
The DWLR Piezometer records this data digitally, allowing for accurate and real-time monitoring of water levels .
Applications:
Groundwater Management: DWLR Piezometers are essential tools for assessing groundwater availability and trends.
Environmental Monitoring: They help track changes in water levels due to natural factors or human activities.
