Product Overview
The HFTA Disc Type Flow Meter is designed based on the force-balance principle, measuring flow by detecting the force exerted by the fluid on a disc.It is suitable for high-viscosity fluids, low Reynolds number conditions (such as crude oil, asphalt, syrup, etc.), and media containing small solid particles. With strong anti-clogging capability and a wide measurement range, it is widely used in process control and metering applications across the oil & gas, chemical, and food industries.
Product Features & Advantages
- Viscosity-Independent Measurement: Not sensitive to changes in fluid viscosity, capable of measuring at Reynolds numbers as low as 500.
- Anti-Clogging Design: No throttling orifice structure, reducing blockage risk and enabling measurement of fluids containing impurities.
- High Accuracy :Measurement accuracy of ±0.5% FS with repeatability of ±0.2%.
- Easy Maintenance:
Simple structure with convenient maintenance; disc can be replaced online without stopping the process. - High Temperature & Pressure Resistance:
Operating temperature range from -20°C to 450°C, and pressure up to 42 MPa, suitable for extreme working conditions. - Complex Fluid Adaptability:
Orifice-free design effectively avoids clogging issues common in traditional orifice plate meters, suitable for complex media such as asphalt, crude oil, pulp, and wastewater. - Optimized Disc Structure:
Improved aerodynamic design reduces adhesion and sedimentation, maintaining stable accuracy even under low-flow conditions. - Anti-Interference Algorithm:
Built-in adaptive filtering algorithm effectively suppresses pipeline vibration and pressure fluctuation interference. - Temperature & Pressure Compensation:
Integrated temperature and pressure sensors enable accurate measurement of gases or fluids affected by environmental changes. - Flexible Communication:
Supports 4–20mA analog output, pulse output, RS485 communication, and Modbus/HART protocols for integration with PLC systems or cloud platforms. - Durable & Safe:
Protection rating IP65–IP68, suitable for outdoor use, with explosion-proof options for hazardous environments.
