LoRa Wireless
LORa is one of the LPWAN (Low Power Wide Area Nerwork) communication technologies. It is an ultra-long-distance wireless transmission scheme based on spread spectrum technology adopted and promoted by Semtech in the United States.
LORa combines digital spread spectrum, digital signal processing and forward error correction coding technology. It has unprecedented performance. Designers can achieve both long distance and low power consumption. Maximize longer distance and lower power consumption The data communication has completely changed the situation in the field of embedded wireless communication.
Wireless Tank Level Sensor
The liquid level transmitter is upgraded by wireless remote transmission. This is an inevitable trend.
The battery-powered Wireless Level Sensor integrates the functions of liquid level acquisition, wireless reporting, and local digital display.
The wireless liquid level transmitter is easy to construct and ready to use. It is mainly suitable for places where power cannot be supplied on site and remote data transmission is required.

chemical tank level sensor
Liquid chemical level sensor is suitable for chemical storage tanks or chemical processing. Especially for highly corrosive liquids.
In chemical storage tanks or chemical processes, there is a risk of corrosive liquids and explosions. Therefore, the requirements for the liquid level indicator are extremely high. SIRD-702 liquid chemical level sensor is a corrosion-resistant guided wave radar level sensor. The maximum range of anti-corrosion guided wave radar level meter can reach 20 meters. It is used to measure the liquid of strong acid and strong alkali. Such as hydrochloric acid, sulfuric acid, hydrofluoric acid, strong alkali and sodium hydroxide. SIRD-702 liquid chemical level sensor adopts all PTFE sealed cable or rod antenna.

Water Level Monitoring System
The Water Level Monitoring System is mainly composed of a telemetry station (Wireless Level Sensor, or wired level transmitter, etc.) and a platform management center.
The telemetry station mainly monitors real-time water level, rainfall, on-site images and other data information in various regions, and uploads it to the platform management center.
The platform management center receives and processes the data sent by the telemetry station through the monitoring and early warning platform, and warns decision makers of decision-making information according to their needs.
At the same time, the system can quickly release relevant early warning information through WEB, mobile terminal, SMS and other means. The Wireless Level Sensor system is a typical IoT system.
Frequently

Which sensor is best for water level indicator?
In terms of experience and cost. A hydrostatic water level sensor would be a good choice.
The wireless remote control water level controller is mainly an intelligent instrument designed for long-distance water tower and mountain top pool water level monitoring. It can not only monitor the change of water level, but also automatically control the start and stop of the water pump.
There are generally three parts, namely the water depth sensor, the transmitter and the receiver.
The transmitter is installed in the water tower. The receiver is installed in the control center. When the sensor is put into water, its output voltage is proportional to the water depth. The higher the water level, the higher the output voltage.
under the control of sequential circuits. Its water depth signal is transmitted to the receiver of the control center through the transmitting antenna. The receiver displays the water level data under the control of the program. And according to the set water level upper and lower limit value and water level alarm value, control the opening of the water pump, and send out the over-limit alarm signal in time.
