1. Introduction to gas waist wheel (Roots) flowmeter

Introduction to gas waist wheel (Roots) flowmeter Gas waist wheel flowmeter is a high-precision, high reliability, and wide range gas monitoring and measuring instrument widely used for flow measurement of various non corrosive gases. The following is a detailed introduction to the gas waist wheel flowmeter:

First, the working principle of the gas waist wheel flowmeter is based on the rotation of the waist wheel (also known as the Roots wheel). When gas flows through the flowmeter, it will push the waist wheel to rotate. The rotational speed of the waist wheel is directly proportional to the flow rate of the gas. By measuring the rotational speed of the waist wheel, the flow rate of the gas can be accurately calculated.

2. Main Features Wide Range: The gas waist wheel flowmeter has an extremely wide measurement range, and according to different specifications, the highest range can reach 1:216, which can adapt to the gas measurement needs of different flow ranges.

. Low starting flow rate: This flowmeter has a low starting flow rate, and according to different specifications, the minimum starting flow rate can reach 0.04m ³/h, which can accurately measure small gas flow rates. High precision and high repeatability: The gas waist wheel flowmeter has long-term stable accuracy, which is not affected by the medium. After long-term operation, the accuracy remains stable and the repeatability is good. Small pressure loss: The pressure loss generated by the flowmeter during the measurement process is relatively small. Depending on different specifications, the pressure loss ranges from 0.08kPa to 0.58kPa, which helps to reduce energy consumption. Hi Working principle of waist wheel flowmeter

gh integration, low power consumption: The intelligent gas waist wheel flowmeter adopts advanced microcomputer technology and high-performance integrated chips, with powerful functions, superior performance, and low power consumption. Compact structure: The flowmeter integrates pressure sensors, temperature sensors, flow sensors and other components internally, with a compact structure that is easy to install and maintain. Digital pressure temperature sensor: equipped with digital temperature sensor and digital pressure sensor, separately calibrated and verified, easy to replace, maintain and use. Segmented correction: According to the flow frequency signal, the instrument coefficient can be automatically linearly corrected in six segments to improve the wide range accuracy of the instrument. Complete data storage function: using E2PROM data storage chip to save user parameters and manufacturer parameters, with timely data saving function to prevent data loss in case of sudden power failure. In the event of a power outage, internal parameters can be permanently saved. Basic complete output: The intelligent flowmeter is equipped with base meter pulse output, working condition or standard condition pulse signal output, and calibration pulse output. Simultaneously providing RS485 interface output, it can also output 4-20mA standard analog signals according to user needs. Data traceability management: Through RS-485 communication interface, real-time database can be queried and analyzed to achieve data traceability management. GPRS real-time management system: Some models of gas waist wheel flow meters have GPRS transmission function, which can achieve transmission function online, timed, and fixed-point, making it easy to b
