Description
Technical Specifications
| Type | Variable Area Water Flowmeters, Ultrasonic Flow meters | |
| Material | Metal | |
| Customized Support | OEM, ODM | |
| Ultrasonic Type | Radar Type | |
| Measurement Principle | Uses sound waves to measure the flow velocity by analyzing the time taken for an ultrasonic pulse to travel between the transmitter and the fluid surface | Utilizes microwave radar waves to measure the flow velocity by detecting the frequency shift of the reflected radar signal from the fluid surface |
| Non-Contact Measurement | Yes | Yes |
| Accuracy (Flow) | 1% to 0.5% | 0.05% FS |
| Accuracy (Level) | 0.25% to 0.5% | ±2% FS |
| Measurement Range (Level) | 9.84 ft (3 m) | 22.96 ft to 131.23 ft (7 m to 40 m) |
| Analog Output | 4 to 20 mA/750 Ω load | 4 mA to 20 mA |
| Relay Output | 4 channels AC 250 V / 8 A or Dc 30 V / 5 A state programmable | – |
| Data Transmission | RS485, RS232 communication, MODBUS protocol (optional) | RS485 or RS232, LoRa (wireless option), NB-IoT (wireless option), 4G RTU (wireless option) |
| Sensitivity to Environmental Conditions | Sensitive to temperature variations, wind, and atmospheric conditions that may affect sound wave propagation | Less affected by temperature, wind, or other environmental conditions; performs well in harsh environments |
| Installation Complexity | Generally easy to install with minimal calibration required. Requires a clear path for the ultrasonic pulse to travel | Slightly more complex installation due to the need for precise alignment, but more robust in diverse conditions |
| Maintenance Requirements | Low maintenance; however, sensor surfaces may need periodic cleaning to ensure accuracy | Very low maintenance; radar sensors are less prone to fouling and generally require less frequent cleaning |
| Cost | Generally more affordable, making it a cost-effective option for smaller projects | Higher initial cost due to advanced technology, but offers long-term savings in maintenance and reliability |
| Suitable Applications | Ideal for applications where cost is a concern and environmental conditions are stable, such as municipal water management, irrigation systems, and small wastewater treatment facilities | Best for challenging environments, large channels, or applications requiring high accuracy, such as in industrial wastewater management, flood monitoring, and hydrological studies |
