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. It can be widely used in liquid level monitoring in urban water supply and drainage, sewage treatment, hydrology and water resources, fire protection, industry and other fields.

From a technical point of view, the Wireless Level Sensors we can currently provide mainly include:

wireless ultrasonic level transmitter

The wireless remote ultrasonic level gauge can adopt two-wire, three-wire or four-wire technology. The power supply circuit and the signal output circuit are independent.

When using DC 24v power supply, a 3-core cable can be used, and the negative end of the power supply and the negative end of the signal output share a core wire.

When using AC 220v power supply, or when using DC 24v power supply. When the power supply circuit and the signal output circuit are required to be completely isolated, a 4-core cable should be used. DC or AC power supply, with 4~20mADC, high and low switch output.

SIRD-702 GWR Corrosive Liquid Chemical 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.


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.

The water tank level monitoring system is widely used in various landmark buildings to complete the automatic water level display and alarm system of the fire water tank. All that is put into the liquid is a liquid level pressure sensor probe. The circuit part is in the junction box on the other end. It is convenient for users to adjust.

water level in a cistern

There are two types of installation methods: M20 x 1.5 thread installation and DN50PN0.6MPa (GB9119-88) standard flange installation. The display instrument is placed in the control room to display the water level of the pool in real time.
