Roots Gas Flowmeter

The gas turbine flowmeter is a high-precision, highly reliable, and wide-range gas monitoring and measurement instrument. The intelligent gas turbine flowmeter is a new type of flowmeter that integrates flow, temperature, pressure sensors and intelligent instruments on the basis of the turbine flowmeter. The gas measured by the intelligent gas turbine flowmeter is natural gas, urban gas, propane, nitrogen, industrial inert gas, and other non-corrosive gases, which is an ideal instrument for measuring.

I. Overview of Gas Turbine Flowmeter 
The gas rotameter is a high-precision, highly reliable and wide-range gas monitoring and measurement instrument. 
The intelligent gas rotameter is a new type of flowmeter that integrates flow, temperature, pressure sensors and an intelligent instrument on the basis of the rotameter. 
The intelligent gas rotameter is an ideal instrument for measuring non-corrosive gases such as natural gas, urban gas, propane, nitrogen, and industrial inert gases.

The main features of the gas rotameter product 
Wide range:
Depending on the specifications, the maximum range can reach up to 1:216. 
Minimum starting flow rate:
Depending on the specifications, the minimum starting flow rate can reach 0.04 m³/h. 
High precision and high repeatability:
The long-term accuracy is not affected by the medium. With long-term operation, the accuracy remains stable. 
Low pressure loss:
Depending on the specifications, the pressure loss ranges from 0.08 kPa to 0.58 kPa. 
High integration, low power consumption
By adopting advanced microcomputer technology and high-performance integrated chips, the entire machine has powerful functions and excellent performance. 
Compact structure:
All the pressure sensor, temperature sensor and flow sensor are integrated within, making the structure even more compact. 
Digital pressure-temperature sensor
Configuration of digital temperature sensor and digital pressure sensor, individual calibration and verification, easy to replace, maintain and use. 
Segmented correction
Based on the flow rate frequency signal, the instrument coefficient can be automatically linearly corrected in six segments, thereby improving the wide-range accuracy of the instrument. 
The complete data storage function:
It uses E2PROM data storage chips to store user parameters and manufacturer parameters. The real-time data saving function can prevent data loss in case of sudden power failure. In the power-off state, the internal parameters can be permanently saved. 
The basic output is complete.
The intelligent flowmeter is equipped with base meter pulse output, working condition or standard condition pulse signal output, and calibration pulse output. It also has an RS485 interface output. According to user requirements, it can also output 4-20mA standard analog signals. 
Data traceability management
Real-time database, via RS-485 communication interface, allows for query and analysis. 
GPRS Real-time Management System
In this series, the B-type meter has GPRS transmission function, which can realize transmission function online, at fixed time intervals, and at fixed points. It is extremely easy to establish a GPRS wireless network system.
