Pointer type metal rotor flowmeter without external power supply

Project Overview

In modern industrial production, flow meters play a vital role in accurately measuring the flow of liquids and gases. As a simple and efficient flow measurement device, the pointer metal rotor flowmeter has attracted much attention for its unique characteristics.

The pointer metal rotor flowmeter is a flowmeter that operates without an external power supply, which allows it to function well in a variety of environments. The core principle is based on the fact that when fluid passes through a pipe, the rotor spins as the fluid flows. The faster the fluid flows, the faster the rotor rotates. The pointer connected to the machine can accurately indicate the flow rate. This simple and reliable working mechanism makes it widely used in places where external power supply is lacking or cannot be used, such as field projects, remote areas or hazardous environments.

In addition to not requiring an external power supply, the pointer metal rotor flowmeter has some other significant advantages. First of all, its structure is relatively simple, consisting of a pair of precision metal rotors with almost no wearing parts. This makes it low maintenance and able to maintain a high degree of stability and accuracy over long periods of operation. Secondly, since there is no direct contact between the rotor and the fluid, the life of the flow meter is also significantly extended. Furthermore, the pointer metal rotor flowmeter is suitable for most liquids and gases, whether it is clean water flow or liquid containing particles, it can be effectively measured.

However, pointer metal rotor flowmeters also have some limitations. For example, since its measurement is based on mechanical rotation, higher flow rates may cause the rotor to exceed its measurement range, thus affecting the accuracy of the measurement. In addition, in the case of high viscosity of the liquid or low gas pressure, the rotation of the rotor may also be affected.

In general, the pointer metal rotor flowmeter plays an important role in industrial production because of its simplicity, efficiency, and no need for external power supply.
