Turbine flow meter flange connection

The GTLWGY series turbine flowmeter is suitable for various industries, including petroleum and chemical industries, meeting the needs of quantitative control, flow monitoring, and over-range alarming. Based on torque balance technology, it offers an accuracy of ±0.5%, excellent repeatability, and fast response. It is lightweight, robust, easy to install, and has low maintenance costs. It supports 4-20mA, pulse, and RS485 Modbus outputs, allowing for seamless integration into control systems.  Explosion-proof models (ExdIICT6 Gb) are available, as well as customized options such as high-temperature resistance (180°C), custom sizes, and PE/PTFE corrosion resistance.
