Mechanical water flow meters refer to a type of flow meter suitable for clean water processes or applications. The working principle of a mechanical water flow meter is to measure the speed of water flowing through a pipe. This causes the piston or turbine to rotate. The volume flow of water is proportional to the rotation speed of the blades. Compared with electronic water flow meters, mechanical water flow meters may become clogged when the water is dirty or contains large particles. When the water flow is low, the mechanical water meter does not work well.
Mechanical Water Flow Meters VS Mechanical Water Meters
Water meter and flow meter are two products with different standards. The focus of the two is also different.
The water meter implements the national standard, and the flow meter implements the industry standard. Water meters require higher requirements than flow meters. Water meters focus on wide-range measurement. And flow meters are suitable for fluid measurement with stable flow rates. Water meters are only used in the water industry, while flow meters are used in major industrial and civil industries. In terms of application range, electromagnetic flowmeters have a wider application range than water meters. However, because the upper and lower limits of flowmeters are relatively narrower than water meters. Water meters are often used in the water industry.

Mechanical flow meters are a type of flow meters that use arrangement moving parts to measure flow. The fluid passes through a series of gears or chambers (positive displacement or PD) or through a rotating turbine or rotor. The mechanical flowmeter is different from electromagnetic and ultrasonic in principle. Mechanical flow meters easily monitor liquid flow rates for water, fuels, viscous fluids and more.

Mechanical water meters have been used by us to measure water consumption for decades. In recent years, with the introduction of smart water, smart city policies. Relevant departments and the water department advocate the use of smart water meters. Smart water meters are widely used. There are still many areas using machinery. Water meters need to be replaced. Smart water meters still have a lot of room for the replacement.
The working principle of the mechanical water meter is that the water flow is driven by the impeller to drive the electromechanical water meter quantitatively. Its function and performance are far from being able to meet the growing technological construction. The disadvantages of the mechanical water meter:
Must use water of similar quality to tap water. And the liquid must not contain rust, gravel, aquatic plants, and other impurities;
It is more difficult to manufacture products with a high range ratio. The range ratio of traditional mechanical water meters is usually less than 80;
Mechanical water meters use impeller gears and other mechanical rotating parts for measurement. The longer the use time, the lower the measurement accuracy;
The pressure loss is great.
Single installation must be strictly horizontal or vertical installation.
For users, the “intelligent water meter” is a tap water meter with remote transmission function.

Water flow meters are flow meters that can diaplay the flow rate of industrial water pipe.
A water flow meter measures the amount of water flowing through a pipe. We have several kinds to choose from, depending on the application, maintenance needs, and budget.

Compared with other flow meters, the mechanical flowmeter relies on the rotation and displacement of mechanical parts to measure the flow rate. Common mechanical flow meters have the following categories.
Tool: Volumetric Flow Rate & Pipe Diameter to Flow Speed Calculator
A common mechanical flow meter is inserted into the pipe and uses a turbine, wheel, or paddle to measure the speed. Then calculate the volume flow by knowing the cross-sectional area of the pipe in which they are installed. A common type of the above-mentioned mechanical flow meter uses a turbine. It rotates as the water flow applies force to the blades. The rotation of the turbine is proportional to the speed of the fluid flowing through it. Once the speed is known, the flow rate can be calculated.
Other mechanical watches use the same basic mechanical principles to measure flow. They operate effectively in full pipelines and when used in areas with the stable flow and almost no turbulence. Mechanical flow meters will operate in all types of liquids. However, it is prone to clogging and performance degradation due to the accumulation of solids on the turbine blades. They also block part of the flow and require regular maintenance of gears and moving parts.
The most common mechanical water flow meter is the turbine flow meter.
