1. How to monitor flow in drainage pipe network

The monitoring of flow in drainage pipe network can be achieved through the 300W-QXC-DR drainage pipe network radar flowmeter. Its core principles, technical characteristics, and operation methods are as follows:

1. Core Monitoring Principle: This equipment calculates flow based on the continuity equation (Q=V × A): Q (flow rate)=V (average flow velocity) × A (cross-sectional area of water passage) Average flow velocity (V): It is obtained by comprehensive analysis of surface flow velocity and embedded hydraulic model, combined with DSP technology and phyTrack fluid velocity detection algorithm, to achieve accurate tracking of flow velocity. Cross section area (A): Real time measurement of water level using ultrasonic ranging technology, combined with dynamic calculation of pipeline geometric parameters.

2. Technical Features and Advantages Non contact measurement adopts radar speed measurement and ultrasonic distance measurement technology, which does not require contact with water flow, avoids interference from water quality, sediment or floating objects, and is suitable for complex environments such as sewage and industrial wastewater.

. The measurement results are stable and not affected by fluid corrosion or mechanical wear. High precision and dynamic analysis flow velocity accuracy: ± 0.02 m/s, resolution of 1 mm/s; Water level accuracy: 2 mm, resolution 1 mm. Real time monitoring of water flow velocity and depth changes, providing statistical data such as instantaneous flow velocity, average flow velocity, water surface width, instantaneous flow rate, and cumulative water volume. Adaptive and maintenance free design for adaptive scenarios:

compatible with various environments such as open channels, natural rivers, and non full pipelines, automatically identifying the direction of water flow and adapting to different flow states from weak to strong flow. Free calibration mode: Long term free calibration measurement can be achieved through a single on-site water level calibration, reducing maintenance costs. Structure and Protection: IP68 waterproof rating, corrosion-resistant casing, operating temperature range of -40 ℃ to 80 ℃, long lifespan and no need for mechanical rotating parts. Efficient deployment and compact design for power supply: The external dimensions are 274 × 170 × 184 mm, with a weight of approximately 2 kg, making it easy to install quickly. Low power consumption and solar power supply: Operating current of 150 mA (12V DC), supporting RS-232/485 communication interface and Modbus RTU protocol, suitable for long-term monitoring in remote areas. III. Key Parameters and Performance Indicators Measurement Range: Flow rate: 0.15-15 m/s Water level: 0.06-2 m Environmental adaptability: Seismic performance: 4 g/5 g (100 Hz) Protection level: IP68 (dustproof and waterproof) Communication and working mode: Continuous working mode, supports remote data transmission and protocol compatibility.

Fourth, Application Scenarios and Values: Municipal Drainage Network: Real time monitoring of sewer system flow, optimization of drainage scheduling, and prevention of waterlogging.

. Industrial wastewater treatment: Track the discharge volume of industrial wastewater, ensure compliance, and optimize the treatment process. Hydrological research: Long term monitoring of natural river or open channel flow to provide data support for water resource manag
