How is the water level in the manhole at the end of the municipal drainage pipe network digitally and safely monitored?

Pain points of water level monitoring in manholes

➤ The complex environment inside the well interferes with data monitoring: there are many suspended solids in the manhole, it is dark and humid, the environment is narrow, sewage overflows, rainwater infiltration and many other uncertain factors have a great impact on the measurement environment.

➤ Data monitoring has blind spots: the measurement of water level by a traditional single liquid level gauge is relatively limited. Deep wells are prone to measurement blind spots. Coupled with the influence of factors such as the complex on-site environment, many equipment failures, and many false alarms, data reliability is low.

➤ Difficult to install and maintain: large number, scattered layout, diverse ownership, and difficulty in obtaining power from an external power supply. However, most battery-powered monitoring equipment on the market has a high frequency of false alarms and requires frequent battery replacement, which increases maintenance work.

➤ Low efficiency: Manual patrols cannot detect existing problems in time, causing great safety hazards.

Meokon Sensor  MD-S981  wireless manhole water level monitor

Meokon Sensor  MD-S981  wireless manhole water level monitor adopts ultrasonic and hydrostatic liquid level measurement technology to achieve simultaneous measurement of downhole liquid level and upperhole liquid level. Equipped with dual probes of ultrasonic level gauge and submersible level gauge to cope with complex working conditions. At the same time, the data model is built-in to calculate reliable water level monitoring data. Timely acquisition of the water level in the cellar and the overflow situation of the manhole provides important help in analyzing the carrying capacity of the pipe network.

Features：

➤ Dual-probe liquid level monitoring: The dual-probe design of ultrasonic liquid level meter and submersible liquid level meter enables no blind spots in downhole liquid level measurement. Under normal circumstances, ultrasonic water level meter is used to measure data. When the water level rises to the blind zone of the ultrasonic water level meter, the input water level meter is used to measure the data.

➤ Low power consumption and long battery life: The product adopts low power consumption design and uses low power consumption microcontroller components. Built-in special lithium battery, equipped with a large-capacity battery box, the battery life is up to 3 years under standard working conditions.

➤IP68, high protection: The outer casing adopts an impact meter that can withstand 200kg strong external force, and IP68 protection level ensures use in harsh environments. Low temperature resistant design, still working normally at -25°C.

➤ Intelligent data configuration: Supports mobile phone Bluetooth configuration of IP address and port, supports independent remote configuration of collection cycle, data reporting cycle, upper and lower thresholds, and has remote zeroing and restart functions. Equipped with sensor abnormality alarms and low battery power alarms, the device can actively push device operating status information, allowing users to easily manage and maintain a large number of devices. Supports Bluetooth configuration, remote configuration, and remote upgrade.

➤ Easy integration: Provides equipment communication protocol docking and DLM equipment health management cloud platform (Lazymao) to realize full life cycle health management services of monitoring terminals, and can be integrated with data from the manhole management platform.

➤ Easy installation: It adopts underground wall-mounted installation, and only requires an ordinary electric drill and screwdriver to complete the installation and disassembly of the equipment. Don’t break the road, don’t set up the pole. It is also very convenient to replace the battery, just plug it in. Get it done quickly.

Monitoring plan for manholes at the end of drainage pipe network

Meokon Seonsor provides a complete set of solutions for manholes, monitoring the status of manhole covers, manhole liquid levels, and pipe network flow in real time. The data model draws conclusions about pipe network siltation and pipe well overflow, and sends the data to the drainage pipe network early warning system to help Supervisory departments can grasp the operating status of the drainage pipe network in real time, quickly identify silted pipe sections and overflow points, and effectively support the daily operation and maintenance of the drainage pipe network and provide reference for drainage during the flood season.

By monitoring the water level in manholes in real time, the Mingkong wireless manhole water level monitor can detect abnormal situations in time and take corresponding measures, such as adjusting the operation of the drainage system to prevent manhole overflows or prevent floods. Wireless manhole water level monitors can provide important information about the operating status of the drainage system, help managers evaluate the performance of the system, and provide a basis for urban flood control and flood warnings.
