Description of DN100 gas turbine flowmeter

Description :

　　This product is suitable for measuring natural gas, dry coal gas, compressed air, etc. It is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields.

　　1、 Main features

　　Adopting precision bearings specifically designed for imported instruments, with high accuracy and good stability, it can be used without refueling for five years under normal conditions.

　　The carefully designed flow channel structure avoids the flow of air between the bearings and improves the medium adaptability of the turbine flowmeter.

　　The unique reverse thrust structure and sealing structure design ensure the long-term reliable operation of the bearing.

　　The flowmeter head can rotate 180 °, making installation and use simple and convenient.

　　Design a rectifier with excellent rectification performance, with very low requirements for the front and rear straight pipe sections (front ≥ 2DN, rear ≥ 1DN).

　　Adopting low-power high-tech, it can work with both internal and external power sources, and the internal battery can work continuously for more than five years.

　　By using RS485 interface to form a network communication system, automated management can be easily achieved.

　　3. Installation

　　1. It is strictly prohibited to weld pipeline flanges online with flow meters. The flow meter should be removed before welding.

　　Before installing the flowmeter, the debris, welding slag, and dust inside the pipeline should be cleaned up.

　　3. In order to facilitate maintenance and not affect the normal transportation of fluids, it is recommended to set up a bypass pipeline as shown in the above figure.

　　4. The flowmeter has a dedicated rectifier with superior performance, so it has low requirements for the straight pipe section.

　　To prevent impurities from entering the flowmeter, a filter must be installed.
