one、product description

Ultrasonic manhole liquid level monitorIt is an intelligent liquid level detection instrument with an integrated design. The product adopts a micro-power design and uses diffused silicon and ultrasonic components for liquid level measurement to achieve liquid level monitoring without blind spots. It can measure the liquid level above the water-logged road surface. Signal measurement.

Ultrasonic components use the principle of ultrasonic pulses for non-contact measurement,and have the characteristics of non-contact,high reliability,high cost performance,and easy installation and maintenance. It can meet most level measurement requirements without contacting the medium. The product has a built-in lithium battery pack that can be quickly replaced for power supply. It is suitable for application scenarios in the wild or without mains power supply,such as urban rainwater and sewage pipe networks,reservoirs,estuaries,lakes,water conservancy,tap water,etc. for liquid level monitoring. Equipment adoptionNB-IoTor4GThe communication method remotely transmits data to the manhole liquid level monitoring system platform to realize real-time monitoring,alarm processing,statistical analysis and other functions of on-site liquid level data.
