Detailed Technical Parameters
1. Performance Specifications
Flow Rate Range: Highly dependent on pipe size, liquid, and transducer installation. Typically from 0.03 m/s to ~25 m/s minimum flow velocity.
Accuracy: ±1.0% of reading ±0.02 m/s (under reference conditions: 10D straight pipe upstream, 5D downstream, well-developed flow profile).
Repeatability: ±0.15% of reading or better.
Response Time: Configurable, typically from 1 to 60 seconds.
2. Pipe and Fluid Specifications
Pipe Material: Any material that transmits ultrasonic energy (e.g., carbon steel, stainless steel, PVC, copper). Cannot be used on lined pipes or concrete pipes with significant wall thickness/porosity.
Pipe Size Range: Typically from DN 15 to DN 6000 (½" to 240") and larger, depending on transducer type and setup.
Lining Thickness: Up to 15 mm (dependent on material).
Fluid Types: Clean, homogenous liquids that can transmit ultrasound (e.g., water, cooling fluids, oils, chemicals, sea water). Not suitable for aerated liquids, slurries with high solids content, or empty pipes.
Fluid Temperature Range: -40°C to +160°C (-40°F to +320°F) (dependent on the specific transducer model used).
Fluid Velocity Range: 0.03 to 25 m/s (0.1 to 82 ft/s).
3. Transducer Specifications (Clamp-On Sensors)
Type: Piezoelectric, clamp-on.
Mounting Methods: V-method, Z-method, N-method (depending on pipe size and fluid).
Standard Cable Length: Typically 6 meters (19.7 ft). Other lengths (e.g., 10m) are available as options.
Enclosure Rating: Typically IP68 (submersible).
4. Electrical Specifications
Power Supply: 100 - 240 VAC, 50/60 Hz, or 24 VDC (varies by order code).
Power Consumption: Approximately 10 VA (max 20 VA during heater operation for condensation prevention).
Outputs: Typically includes:
One or two 4-20 mA analog outputs (active/passive, programmable for flow rate, velocity, etc.).
Relay / Alarm Outputs: Typically two programmable SPDT relays (e.g., for alarms, empty pipe detection, flow direction).
Inputs: Typically includes:
One or two 4-20 mA analog inputs (e.g., for temperature compensation).
Communication: Standard HART® protocol (over the 4-20 mA loop). Other options like PROFIBUS-DP or Modbus RTU may be available depending on the exact order code.
5. Environmental Conditions
Operating Temperature: -20°C to +60°C (-4°F to +140°F) for the transmitter unit.
Storage Temperature: -40°C to +70°C (-40°F to +158°F).
Enclosure Rating (Transmitter): IP65 / NEMA 4X (dust-tight and protected against water jets).
6. Physical Specifications (Transmitter Unit)
Housing: Plastic (Polycarbonate) or aluminum, depending on variant.
Dimensions (H x W x D): Approximately 260 x 190 x 115 mm (10.2 x 7.5 x 4.5 inches).
Weight: Approximately 2.2 kg (4.85 lbs).
Display: Backlit LCD for local readout and configuration.
Keypad: 5-button keypad for navigation and setup.
7. Certifications and Approvals
Typically carries CE marking.
May carry other regional approvals depending on the market (e.g., EAC, UKCA). Specific certifications should be checked on the product label or datasheet.
Key Features and Benefits
Non-Invasive Installation: No need to cut the pipe or stop the process, reducing installation cost and risk.
Bidirectional Flow Measurement.
No Pressure Drop: Since there is no contact with the fluid.
Wide Pipe Size Range: One device can be used on a vast range of pipe diameters.
HART Communication: Allows for easy configuration, calibration, and diagnostics using standard tools.
Integrated Data Logger: Some variants can store flow data internally.
