Roots flowmeter, also known as waist wheel flowmeter, is a high-precision measuring instrument mainly used for continuous or intermittent measurement of gas or liquid flow in pipelines. It belongs to a type of volumetric flowmeter, which has the characteristics of high accuracy, good reliability, light weight, long service life, and low operating noise.
The measuring medium suitable for Roots flowmeter includes but is not limited to non corrosive gases such as artificial gas, city gas, propane, nitrogen, inert gas, etc. These gases are commonly used in industrial production and daily life, with high requirements for measurement accuracy and reliability.
The basic working principle of a Roots flowmeter is to measure fluid flow by rotating a pair of synchronously rotating rotors in a pipeline filled with medium, using the volume change between the rotors. This type of flowmeter is suitable for measuring dry and wet gas (i.e. associated gas), and is not sensitive to flow, but may produce significant noise when the lumbar wheel rotates at high speeds.
1. High precision: The measurement accuracy of Roots flowmeter is usually between ± 1.0% or ± 1.5%;
2. Long lifespan and good reliability: Due to the precision machining and balance testing of the external rotor of the Roots flowmeter, there is no friction tampering and it has good lubrication performance;
3. Light weight: Designed to be lightweight, easy to install and move;
4. Low noise: Due to design optimization, the operation noise of Roots flowmeter is relatively low, suitable for occasions that require quiet environment;
5. Easy to use: Roots flowmeter can indicate cumulative flow rate, instantaneous flow rate, etc. on site, and supports multiple signal output methods such as pulse signal, analog signal, communication protocol, etc., making it easy to integrate into various automation systems;
6. Wide range ratio: suitable for measuring gas flow with large load changes;
7. Rich communication interfaces: equipped with RS-485 communication interface, supporting remote data transmission methods such as GPRS/CDMA and the Internet, facilitating centralized data collection and real-time monitoring;
8. Strong anti-interference ability: The circuit adopts surface mount installation technology, with a compact structure and strong anti-interference measures, which improves the reliability of the system.
