Ultrasonic Inline Water Flow Meter - Flanged End Connection

Product Details

An Everest Ultrasonic Inline Flow Meter is a type of flow meter designed to measure fluid flow using ultrasonic waves, installed directly in the flow path. These meters are non-intrusive, highly accurate, and suitable for a wide range of fluids, including liquids, slurries, and, in some cases, gases. Working Principle Ultrasonic flow meters work based on two primary principles: Transit-Time Principle: Two ultrasonic transducers are installed diagonally opposite within the flow tube. Ultrasonic signals are sent both upstream and downstream. The time difference between upstream and downstream signals is proportional to the flow rate. Key Features Non-Intrusive Measurement: No moving parts; minimal wear and tear. Bidirectional Flow Measurement: Capable of measuring flow in both directions. Wide Flow Range: Can handle various flow rates with high precision. Multi-Fluid Compatibility: Works with clean and some particulate-laden liquids. Digital Outputs: Provides readings via protocols like Modbus, HART, or analog signals (4-20 mA). Pressure and Temperature Compatibility: Inline meters are designed to withstand specific operating conditions. Applications Water Treatment Plants: Monitoring potable and wastewater flows. Chemical Industry: Measuring corrosive and non-corrosive liquid flows. Food and Beverage: Monitoring flow of beverages or viscous fluids like syrups. Oil & Gas: Measuring crude oil, refined products, and slurries. HVAC Systems: Measuring water flow in heating and cooling systems. Advantages High Accuracy: Typical accuracy ranges from ±0.5% to ±1% of the reading. No Pressure Drop: Flow is measured without restricting the pipe's cross-section. Minimal Maintenance: No moving parts or components exposed to the fluid. Flexible Installation: Can be installed horizontally or vertically. Limitations Clean Fluids Preferred: Transit-time meters require clean fluids for best performance. Sensitivity to Air Bubbles: Air in the pipeline can reduce accuracy. Initial Cost: Higher upfront cost compared to mechanical flow meters. Installation Considerations Straight Pipe Lengths: Ensure sufficient upstream and downstream straight pipe sections (typically 10x pipe diameter upstream, 5x downstream) for laminar flow. Orientation: Install in a position to avoid bubble or sediment interference (e.g., horizontal pipe with electrodes on the side). Temperature and Pressure Ratings: Verify compatibility with the operating conditions. Calibration: Inline ultrasonic meters may require periodic calibration to maintain accuracy.
