What is one characteristic of a Displacement Meter?

A displacement meter is specifically designed to measure the volume of water flowing through it by using the displacement of a known volume within the meter. This characteristic makes it particularly suitable for domestic water applications, such as residential water supply systems, where accurate measurement of lower flow rates is essential.

These meters operate based on mechanical principles and can effectively measure both low and moderate flow rates, making them an ideal choice for household usage. They benefit from simplicity and reliability in domestic settings, facilitating accurate billing based on actual consumption.

The other characteristics provided in the options do not accurately describe displacement meters. For instance, they are not limited to high flow rates; they are designed to function well at low flow which is typical in domestic scenarios. They do not require electrical power, as their operation is predominantly mechanical, further supporting their suitability for residential use. Additionally, they are not restricted to measuring only hot water; they can measure water across a range of temperatures, provided the design accommodates it. Thus, selecting the correct characteristic highlights the practical application of displacement meters in typical water consumption scenarios.
