Groundwater Level Monitoring System




GROUND WATER LEVEL ONLINE MONITORING SYSTEM

DESCRIPTION:

Groundwater level monitoring is important to know the information of water column head under the earth’s surface. As per the compliance, it helps to observe the changes in the quantity of groundwater level accordingly. The continuous groundwater monitoring provides the detailed data and helps to make the observations easily for future projections and development.

Level sensor also known as Piezometer plays the important role to provide all the information beneath the earth’s surface. It monitors the level at which the water table starts. It can be installed in wells, bore wells and tube wells at the desirable depth to know the available water in sand pores and aquifers. Level sensor is connected with specific wires up to the surface level then connected to the electromagnetic flow meter and telemetry system which transmits the data to the server for real time access on data management software irrespective of location. Various changes in the groundwater can be observed with the help of different type of level sensors. Collecting the accurate long term data of groundwater level monitoring will lead to make the proper planning for the development and management of groundwater level and will avoid the scarcity of water in the future.

KNOW WHAT COMPLIANCE SAYS

Central Ground Water Authority (CGWA) has issued the guidelines to groundwater users including industrial/ infrastructure/ mining projects to measure the amount of groundwater extraction. According to the compliance, installation of an online groundwater monitoring sensor with a data logger or telemetry system is mandatory, non-installation of the system will be considered illegal for the users withdrawing water from the ground. For the withdrawal of water more than 100 KLD, users are required to submit the Impact Assessment Report/ Hydro-geological Report/ Water Audit Report. Non-issuance of required reports before the submission date for NOC will cause rejection of applications/NOC of the user as per the regulations. Users not adhering to the submission dates are liable to pay the penalty/ Environmental Compensation amount according to the guidelines.

PRODUCT DESCRIPTION:

The IOT based groundwater level monitoring sensor measures the water level which is connected to the server for data acquisition and real time data access on data management software. It meets the compliance and helps to generate the required reports. The human-error free system and the reliable software is preferred solution for the issued guidelines.

The Hydrostatic level sensor is a submersible sensor made up of SS316L, having key feature to measure the level of liquid. The sensor is made of aluminum pressure die-cast, coated with epoxy polyurethane which have protection class of IP68. It possess the ability to convert the signals into RS485 output and transmits the data on data logger for real-time data access. The sensor is reliable and transmits the accurate data. Installation of the sensor at specific depth measures exceedance and falling of the water level. The hydrostatic level sensor can be used to measure the ground water level, level in water tanks, well, tube wells and bore wells. It is the most preferred solution to access the hydrostatic data.

SYSTEM FEATURES
APPLICATIONS OF LEVEL SENSOR

The level sensor is used for the following purpose:

VISUALIZATION OF DATA

Ecolyser is the real-time data management software which can be handled simply. The sensors are connected to the server for data acquisition that can be accessed on Ecolyser. The cloud based storage system provides the access to the historical data for information and analysis. Reports can be generated according to the compliance and for O&M of the system. It keeps the user notified by sending notifications whenever changes occur in monitoring.

SOFTWARE FEATURES

1. Real-time data access on smart devices
2. Enabled with site details respectively to sensor position for tracking multiple locations on one dashboard
3. Push notifications on alarming fluctuation according to the threshold set by user easily
4. Access to historical data for smart report generation
