Electromagnetic Flow Meter
The GTLWGY Series turbine flowmeter is suitable for monitoring and measuring flow rates in water, milk, juice, seawater, and corrosive wastewater. Based on torque balancing technology, it is a high-precision velocity flowmeter with an accuracy of up to ±0.5%, excellent repeatability, and fast response. Its lightweight and rugged design ensures easy installation and low maintenance, making it ideal for applications in the petroleum, chemical, water treatment, and energy sectors. The sensor supports 4-20mA, pulse, and RS485 Modbus outputs, enabling seamless integration with control systems for quantitative batching and over-range alarms. For hazardous environments, we offer explosion-proof models certified to ExdIICT6 Gb. Customizable options include high-temperature resistance (180°C), product dimensions, and corrosion-resistant (PTFE) models.
