What is the difference between turbine and mechanical flow meters

When running any farm, it is very important to organize a competent and accurate accounting of consumable materials or substances. This issue is especially relevant in the municipal sphere. This is a very vast area, but one of its main components is the water supply system.

Application of flow meters

In recent years, more and more residents of our country have been installing special flow meters (water meters), which allow not only to control the flow of liquid, but also to save personal funds.

Flowmeters can be used to account for and measure liquids or gases, but only if substances pass through this device. In the household sphere, the product is called simply a counter, but such a name is technically incorrect. The flow meter is installed in the main line through which the liquid or gas passes, or in close proximity to it (for example, through the ZKS wedge valve).

Currently, you can purchase several varieties of the device, the main differences of which are related to the principle of operation. In our article, turbine and mechanical meters will be considered, but later we will definitely talk about three more:

Features of the turbine flow meter

Devices of this type are used to measure various liquids that do not contain chemically active substances. Also, such a medium should be characterized by low viscosity. The turbine device is suitable for metering gas mains.

The principle of operation is based on a volumetric meter. When a liquid or gas passes through the device, the blades begin to rotate inside the turbine. The mechanical or electronic part of the device translates these rotations into numerical expressions, which are displayed on the display. The most striking example of this equipment is a standard household water meter.

Features of the mechanical flow meter

This device functions depending on the vibrations of the piston located in a sealed housing. Both liquids and gases can be measured. Since the equipment is characterized by large dimensions, it can mainly be used at industrial facilities or where accounting for passing liquids with high viscosity is required.

These devices can be operated at extremely low or high temperatures, while the accuracy will remain at a high level. The measured substance, after the air disappears from the pipe, begins to rotate the piston. By moving it from its place, the liquid or gas moves further along the pipe through the outlet.
