2025-04-24 17:33:08

System Overview

Doppler ultrasonic flowmeter brings you professional service，this system consists of two parts: the sensor end and the host end, aiming to achieve monitoring and intelligent control of water accumulation in cable pipelines. Through advanced sensing technology and communication methods, it ensures the safe and stable operation environment of cable pipelines.

Sensor end design

1. Measurement technology: Using a combination of static pressure sensors and conductivity sensors for accurate sampling of liquid level data, ensuring the accuracy and reliability of measurement results.

2. Data transmission: Using LoRa RF technology, the collected liquid level data is stably transmitted to the host end to ensure the timeliness of data transmission.

3. Structural design

-The shell is made of ABS material and equipped with glue filling technology to achieve IP68 protection level, which can adapt to various harsh environments.

-The back panel is made of stainless steel material, which is easy to install and fix, enhancing the convenience of system installation.

4. Appearance design: The main color is orange, which is easy to identify and locate in complex environments.

5. Power supply system: Powered by 4 × 19000mAh lithium-ion batteries, the battery can last up to 60 months under the condition of transmitting data every 5 minutes, reducing maintenance frequency and providing sufficient power support for stable operation of the sensor end.

Host side design

1. Material and power supply

-The shell is made of black ABS material, which has good durability and protection.

-Adopting dual power supply mode, with built-in 11.1V 5000mAh lithium battery and charging circuit. During normal power supply, the charging circuit charges the lithium battery while ensuring the full functional operation of the system; In the absence of external power supply, the lithium battery driven host can continue to work for more than a week and retain data acquisition and communication functions, but the control function will be disabled. 

2. Data exchange

-Utilize wireless radio frequency LoRa to receive data from sensor terminals, and send the data to servers via wireless 4G to achieve remote transmission and centralized management of data.

-Doppler ultrasonic flowmeter brings you professional service,reserve RS485 interface for system expansion and device integration in the later stage; Reserved 4-20mA interface, but this interface is only for reserved space and is not equipped with relevant hardware devices.

3. Doppler ultrasonic flowmeter brings you professional service，function implementation: Equipped with two relay outputs, it can control relevant external devices during normal power supply; By real-time monitoring of the liquid level value, it is determined whether it is necessary to drain the accumulated water in the cable conduit, achieving intelligent control.
