Advantages of Mechanical Water Meter | Disadvantages of Mechanical Water Meter
This page covers advantages and disadvantages of Mechanical Water Meter and its basics. It mentions benefits or advantages of Mechanical Water Meter and drawbacks or disadvantages of Mechanical Water Meter.
Water meter is a device which measures volume of water flowing through pipe line at residential and commercial buildings. Water meters measure total flow in cubic meters as well as rate of flow. There are different types of water meters based on their technology viz. mechanical, electromagnetic, ultrasonic etc.
What is Mechanical Water Meter?
Mechanical meter uses impellor in its construction. When water passes through the meter, impellor is rotated. This rotation is directly proportional to volumetric reading on the meter.
The mechanism of mechanical meter is calibrated by adjustable device which is preset and sealed for security reasons. These water meter types are available in various sizes. It requires full water flow in pipeline for better measurement results.
These meters are suitable for clean water measurement with little turbidity. They are commonly used in urban water supply systems.
Following are the general features to be considered for selecting
appropriate mechanical water meter for your application.
• Meter should be leak proof. Hence it should be totally sealed in metallic outer body.
• It should be repairable without affecting regular water supply.
• It should be easy to maintain and requires removable mechanism.
• Impeller should be protected by metallic cover.
• It should have reliable sensitive metrology and low pressure loss.
• Meters should conform to ISO : 4064-2005 specifications.
