What is Piezometer ?
A piezometer is a device used to measure water level fluctuations in a borewell.
A piezometer records water table depth on a regular basis and provides detail on changes in static water level in a borewell
As per CGWA Compliances Piezometer are required to be installed within a plant premises for Groundwater monitoring purposes.
Groundwater Level Recorder
A piezometer with telemetry system has 4 main unit:
- 1. Probe
- 2. Metered Cable
- 3. Display unit
- 4. Modem with 4G Sim
Piezometer Installation with telemetry system video
Installation of Piezometer using Telemetry System?
How Piezometer is installed ?
For installing piezometer a borewell is required upto a depth of 50 meters (minimum)
A probe is Installed inside borewell beneath the static water level. The probe is connected with metered wire to display unit
Display unit shows the exact reading of static water level at a given time and readings fluctuate with seasons
Display unit is connected with a 4 G sim which transfers realtime data on cloud
Data present on cloud can be fetched using ID/Password and real time reports can be seen
What is the Use of Piezometer ?
A piezometer successful installed can provide input on water table fluctuations i.e water table can be monitored
A piezometer can decide if there is over exploitation of water or rainwater harvesting measures are successfully implemented within a given area
Frequently Asked Questions
1. What is a piezometer?
A piezometer is an instrument used to measure the pressure of liquid or gas in a system. It is commonly used to measure the pressure of groundwater or the pore pressure within soil or rock.
2. What are the different types of piezometers?
Standpipe Piezometers, Pneumatic Piezometers, Vibrating Wire Piezometers, Digital Piezometers
3. How does a piezometer help in construction projects?
Piezometers help monitor pore water pressure, which is crucial in construction projects to ensure stability and safety. They provide data that can prevent soil liquefaction, landslides, and other ground failures.
4. Where can I purchase a piezometer?
Piezometers can be purchased from specialized geotechnical and environmental engineering suppliers. Ensure to buy from reputable manufacturers to guarantee quality and support.
5. How can I ensure the accuracy of my piezometer readings?
Perform regular calibration checks, Keep the device in good working condition through regular maintenance and inspections.
6. What are common issues with piezometers and how can they be resolved?
Ensure the piezometer is free from sediment or debris. Regular cleaning and maintenance can prevent this.
Regular calibration checks and adjustments are necessary to maintain accuracy.
7. What is a piezometer used for?
A piezometer is used to measure groundwater levels and pressure within soil or rock layers, providing critical data for hydrogeological studies.
8. What is a piezometer manometer?
A piezometer manometer is a device that combines functions of a piezometer and a manometer, allowing for measurement of both groundwater pressure and fluid column height.
9. What is the difference between a piezometer and an inclinometer?
A piezometer measures groundwater pressure while an inclinometer measures the angle of slope or tilt of structures, helping assess stability in engineering applications.
10. Which liquid is used in a piezometer?
Typically, water is used in piezometers; however, other liquids may be used depending on specific applications.
11. What is vacuum pressure also called?
Vacuum pressure is also referred to as negative pressure or sub-atmospheric pressure.
12. What is the principle of a piezometer?
The principle of a piezometer relies on measuring the height of a fluid column that reflects the hydraulic head at that point in the groundwater system.
13. What is called a manometer?
A manometer is an instrument used to measure the pressure of gases or liquids by balancing them against a column of liquid.
