Ultrasonic Doppler Pipeline Flow Monitoring Instrument

This high-precision instrument features battery-powered operation, ultra-low power consumption, IP68 rating, and wireless communication. It is specifically designed for monitoring sites where power supply is unavailable and environments are harsh, such as pipelines or manholes.

Users can access real-time monitoring data via the integrated high-definition LCD screen, while the wireless module enables remote data management through cloud platforms. Its design ensures easy installation, extended battery life, and stable performance.

Ultrasonic Doppler Pipeline Flow Monitor
Key Features
⚡ Low Power
Ultra-low power consumption for extended battery lifespan.
🛡️ IP68 Protection
Fully waterproof and damp-proof for underground use.
📊 Multi-Measurement
Integrates flow velocity, water depth, and temperature.
🌊 Velocity-Area Method
Flow measurement with zero head loss; no weirs/flumes needed.
🎯 High Accuracy
Ultrasonic Doppler principle ensures precision even at low initial velocity.
🌡️ Temp Compensation
Built-in sensor compensates for temperature impact on sound velocity.
Main Functions

1. Multi-level Alerts: Adjusts data collection and transmission cycles based on rainfall and runoff requirements to meet rainy-day scheduling needs.

2. Data Breakpoint Resume: Equipped with storage functionality to save data during signal interruptions, resuming transmission automatically once connectivity is restored.

3. Remote Configuration: Allows remote access to operating modes and sensor parameters via a service platform, Bluetooth, or local interface.

Installation Guidelines
  • Install in environments with calm, stable water surfaces without backflow or vortices.
  • Avoid drainage outlets, vertical drops, flow barriers, and sharp bends to ensure accuracy.
  • Mounting brackets require stable manhole walls; avoid structurally complex or deteriorated surfaces.
  • At pipeline junctions, install the Doppler sensor at the base, facing the water flow directly.

Frequently Asked Questions
What's the typical lead time for an order?
Standard models are usually shipped within 15–30 days, while customized units require approximately 30–45 days depending on the configuration.
Can this device be installed in a manhole without external power?
Yes, the device is specifically designed for manholes. It is battery-powered with a 76AH capacity and features ultra-low power consumption for long-term independent operation.
Does the instrument support remote data monitoring?
Yes, it supports 4G, NB-IoT, and Bluetooth communication, allowing real-time data transmission to cloud platforms for remote monitoring.
How does the device handle signal interruptions?
It includes a "Breakpoint Resume" feature, storing data locally during signal loss and automatically uploading the historical data once the network is restored.
Is the sensor resistant to harsh sewage environments?
Absolutely. The entire unit is IP68-rated, meaning it is dust-tight and protected against long-term immersion in water, making it ideal for sewage and drainage pipes.
What documents are provided for international shipping?
We provide a full export documentation package including Commercial Invoice, Packing List, Bill of Lading, and Certificates of Conformity (COC).
