Gas Turbine Flow Meter Overview
The gas turbine flowmeter employs advanced microprocessing technology, boasting strong functionality, high computational accuracy, and reliable performance. Its main technical specifications have reached the advanced level of similar foreign products. It is an ideal instrument for gas measurement in the oil, chemical, power, metallurgical industries, industrial and civil boilers, as well as for urban natural gas, gas pressure regulation station, and gas trade measurement. Its working principle is as follows: when the gas enters the flowmeter, it first passes through a special rectifier to accelerate. Under the action of the fluid, the turbine overcomes the resistance torque and friction torque and begins to rotate. When the torque reaches equilibrium, the speed stabilizes. The turbine speed is proportional to the gas flow, and the magnetic resistance of the sensor is periodically changed by the magnets on the rotating signal disk, thereby outputting a pulse signal proportional to the fluid. The product features include:
1. Utilizing imported precision bearings from Germany specifically for instrument use, offering high accuracy, excellent stability, and a wide range (20:1). The small bore can be oil-free for up to five years under normal operating conditions, while the large bore requires only occasional oiling, ensuring convenient usage.
2. A meticulously designed channel structure prevents air flow between bearings, enhancing the medium adaptability of the turbine flow meter.
3. A unique reverse thrust and sealing structure design ensures long-term reliable operation of the bearing.
4. Utilizing magnetic resistance elements in place of magnetic sensitive coils eliminates magnetic attraction, enhances detection sensitivity, further reduces the startup flow rate, and improves product stability and reliability.
5. Independent core design with good interchangeability and easy maintenance.
6. Integrating temperature, pressure, flow sensors, and an intelligent flow totalizer, it can automatically track and correct the measured gas temperature, pressure, and compression factor, directly measuring the standard volume flow rate and total volume of the gas.
7. Key performance indicators meet international advanced levels and comply with ISO 9951 standards.
8. Utilizing micro-power consumption high-tech, it operates with either internal or external power sources, with the internal battery lasting for over five years continuously.
9. Powerful features with four compensation methods, three pulse signal outputs, three ways to record historical data, and two standard current signal output options available.
10. Network communication systems can be easily established through RS485 interfaces for convenient automation management. The RS485 communication protocol conforms to MODBUS standards.
11. The table head can be rotated freely up to 180°, with easy installation.
