Drainage network collection system

1.Introduction to Drainage network collection system

Drainage network collection system is a custom designed, computer-aided management technology for a specific sewer network that collects relevant sensor information.GW1 Drainage network collection system is an Internet of Things monitoring terminal independently developed by our company and is specially developed for applications in the field of pipeline monitoring.

GW1 Drainage network collection system products have the characteristics of high protection level, low power consumption, strong corrosion resistance, etc.It integrates data collection, data storage, power supply, display, data transmission and other functions.

It adopts wireless communication functions such as 4G and NB-IOT.The conventional products do not require external power supply, are convenient to install and maintenance-free.

The product can be externally connected to various sensors such as Doppler flowmeter, radar level meter, ultrasonic level meter, radar flowmeter, water quality COD/ammonia nitrogen/PH/conductivity, etc.

2.Advantages and features of Drainage network collection system

Can be connected to a variety of external sensors, strong applicability, can measure instantaneous flow and accumulated flow

Low power consumption, maximum working current is only 15mA, standby current is only 0.3mA

Small footprint, simple and fast installation

Adopt the independently developed digital core acquisition control module, with stable functions and simple operation

Supports various wireless data transmission technologies such as 4G, NB-IOT, Zigbee, Lora, etc., making data transmission convenient and reliable

The system adopts a smart environment monitoring cloud platform, which can easily browse and view data and device management through computers, mobile phones and other methods.

The equipment structure is reasonable, which can ensure long-term continuous measurement outdoors

Remotely modify the pipe diameter

4-channel power supply independent control, can set sampling period and sampling interval

With remote time calibration function
