Is the metal rotor flowmeter a positive displacement flowmeter?

Project Overview

In industrial production and fluid control processes, it is very important to accurately measure the flow rate of fluids. As a common flow measurement device, the volumetric flowmeter is widely used in various fields. So, is the metal rotor flowmeter a positive displacement flowmeter? This article will take an in-depth look at the principles and advantages of positive displacement flowmeters and metal rotameter flowmeters.

Positive flow meter is a device that determines flow rate by measuring the change in volume of fluid passing through the cavity inside the meter. Simply put, it works by directing fluid into a specifically shaped chamber or pipe and calculating the flow rate by measuring the volume the fluid occupies in this space. Because they measure the volume of fluid, positive displacement flow meters have extremely high accuracy in flow measurement.

The metal rotor flowmeter is a common volumetric flowmeter, which uses a metal rotor as the core component. Rotors are often highly precisely constructed and sized to accurately measure the volume of fluid passing through the device. Metal rotor flow meters mainly include rotors, analog sensors, rotor bearings and output devices.

The working principle of the metal rotor flowmeter is: when the fluid passes through the pipe of the flowmeter, the rotor will also be driven. Its core component is a floating rotor whose position is determined by the fluid flow rate.

Metal rotameter has many advantages. First of all, it is widely suitable for the measurement of liquids and gases, including water, oil, liquefied gas, etc. Secondly, the metal rotor flowmeter can be applied to different flow rates and temperature ranges and has strong adaptability. In addition, the device has a simple structure, is not easily damaged, has a long service life, and has low maintenance and calibration costs.

To sum up, the metal rotor flowmeter is a variable area flowmeter, which ensures the accuracy of flow measurement by measuring the volume of fluid passing through the device.
