External Thread Connection Turbine Flow Meter
Page Features
■ Multiple amplifier options
■ Suitable for small-diameter pipe installation
■ Compact design
■ Multiple thread specifications available
■ Full stainless steel construction
Product Overview
As fluid passes through the sensor, the turbine rotor rotates under fluid force. After electrical processing, it outputs corresponding flow data. Suitable for measuring impurity-free liquids, it can output pulse frequency signals for detecting instantaneous flow and totalized volume. It offers high signal resolution, wide range, and accuracy, typically reaching ±1%FS, ±0.5%FS, with high precision up to ±0.2%FS. Advantages include compact structure, clear readability, high reliability, immunity to external power interference, lightning resistance, and low cost.
Performance Features
■ Low pressure loss; turbine rotor with anti-corrosion capability
■ Advanced ultra-low-power microcontroller technology for strong functionality, low power consumption, and superior performance
■ EEPROM for power-off protection of accumulated flow and meter coefficients (protection >10 years)
■ Supports amplifier-sensor separation (up to 15m)
■ Strong resistance to magnetic interference and vibration; reliable performance and long lifespan
■ Corrosion-resistant, suitable for acid/alkali solutions
■ Low lower-limit flow velocity; wide measurement range
■ Insertion type available for large-diameter measurement, featuring low pressure loss, affordable cost, non-stop removal, and easy installation/maintenance
■ Wide turndown ratio: 1:20 for medium/large diameters; 1:10 for small diameters
