I. Introduction

Wireless ultrasonic level gauge/level gauge is a low-power and high-performance product with integrated IP68 protection level of

ultrasonic sensor, wireless NBiot or LoraWan remote transmission, and large-capacity battery. It is widely used in municipal, water,

and smart cities. , automation, etc.

II. System

The wireless ultrasonic distance/level system consists of: application objects, long-life wireless ultrasonic range finder, cloud management

software, the key product is "low-power wireless ultrasonic sensor", cloud management software is a software customized product.

III. Product review：

1. Ultrasonic ranging products provide reliable continuous level or distance measurement for water, liquid, glue or solid materials. These 

   sensors are ideal for applications ranging from 10cm to 200cm.

2. The ultrasonic range finder can be easily connected to the control system electronically and mechanically, combined with the most

advanced ultrasonic technology and processing algorithms, the design is reasonable and the complete system is integrated.

3. Ultrasonic sensor conforming to IP68 standard, the product conforms to RoHS.

4. Ultrasonic distance/level meters can also provide accurate non-contact measurements for applications such as factory automation, process

control or tank level monitoring.

5. Ultrasonic rangefinders are powered by 3.6~5.5V DC battery or 9-30V DC, they use asynchronous UART TTL signal to communicate with

customer's control system. Their power-on time is very short (less than 300ms), which allows system integrators to develop very low-power

operation, where 3.6~5.5V DC is briefly applied to the sensor to obtain a distance measurement and then removed. This capability is especially

important in battery powered installations. The sensor is protected against overvoltage and reverse polarity in both DC power and UART

communication. Perform continuous temperature compensation for precise measurement accuracy.

6. Provides wireless communication with LoraWan or NBiot sensors (5 years battery life if data is transmitted every 2-3 hours).

7. Sensors stand out from others because of their user-friendly setup, versatile control options, field-proven reliability, and affordable cost.
