The high-precision GTLWGY Series turbine flowmeter utilizes torque balancing technology to deliver ±0.5% accuracy, excellent repeatability, and fast response. Featuring a rugged, lightweight design with low maintenance, it seamlessly integrates via 4-20mA, pulse, 0-10v,0-5V or RS485 Modbus. For demanding environments, custom options include ExdIICT6 Gb explosion-proof certification, high-temperature resistance up to 180°C,IP68 protection level and corrosion-resistant PTFE models.
High Precision: Delivers up to ±0.5% accuracy with excellent repeatability.
Fast Response: Captures transient flow changes instantly, ideal for quantitative batching.
Wide Turn-down Ratio: Performs reliably across broad flow ranges with a low pressure drop.
Compact & Rugged: Lightweight design with a durable stainless steel housing for easy installation.
Smart Integration: Supports multi-signal outputs including 4-20mA, Pulse, and RS485 Modbus.
Harsh Environment Ready: Optional ExdIICT6 Gb explosion-proof and 180°C high-temperature and IP68 waterproof for demanding processes.
