INSTRUMENTS TO MEASURE AND RECORD WATER (AS PER CGWA)
These instruments play a crucial role in water management by providing accurate and reliable measurements of groundwater levels and water flow rates. They help in assessing water availability, monitoring water usage, and making informed decisions for sustainable water management practices.
Proper installation and calibration of these instruments are crucial to obtaining accurate and reliable measurements of water levels and flow rates. It is recommended to consult with professionals. Allances ensures these guidelines for the specific installation process to ensure optimal performance.
Piezometer - Manual
A piezometer is an instrument used to measure and record groundwater levels. It consists of a long, slender pipe with a small opening at the bottom. When inserted into the ground, the pipe allows water to enter and reach the same level as the groundwater table. The water level is then manually read using a graduated scale marked on the pipe. Piezometers are installed by drilling a borehole and placing the pipe into the hole, ensuring it reaches the desired depth.
A piezometer works based on the principle of hydrostatic pressure. The water level inside the pipe is then manually read by observing the position of the water against a graduated scale marked on the pipe.
DWLR with Telemeter
A Digital Water Level Recorder (DWLR) with Telemeter is a modern instrument used to measure and record groundwater levels electronically. It consists of a pressure sensor that detects the water pressure in the well or borehole. The sensor is connected to a data logger that records the water levels at regular intervals. Telemetric technology allows remote access to the data. DWLRs are installed by securely fixing the instrument in the well or borehole and calibrating it to accurately measure and record the water levels.
Allances Install the data logger near the well or borehole, ensuring it is protected from environmental factors and securely mounted.
Digital Water Flow Meter
A Digital Water Flow Meter is used to measure and record the flow rate of water in a pipe or conduit. It typically consists of sensors that detect the flow velocity and a digital display that shows the flow rate. The meter is installed by attaching it to the pipe or conduit and ensuring a proper seal. Some digital water flow meters can also be integrated with data loggers or telemetry systems to record and monitor the flow data over time.
The flow meter uses the detected flow velocity and the cross-sectional area of the pipe to calculate the flow rate using the principles of fluid dynamics. The calculated flow rate is displayed on a digital screen, allowing for easy reading and monitoring.
