What is a submersible level sensor?
With the development of modern control and Internet of Things technology, as well as the increase in the adoption of industrial automation, the technological advancement of liquid level sensors, and the increase in the use of energy and power sectors, liquid level sensors have achieved unprecedented development. It can be seen that the liquid level sensor has great potential for development now and in the future.

Liquid level sensors are currently widely used in water plants, sewage treatment plants, urban water supply, high-rise pools, water wells, geothermal wells, mines, industrial pools, oil pools, hydrogeology, reservoirs, rivers, oceans and other fields In the liquid level measurement, and play an increasingly significant role. Today's liquid level sensors have been widely used because of their simple structure, high sensitivity, good dynamic response, strong overload resistance, and ability to work under harsh conditions such as high temperature, radiation, and strong vibration. The measurement is as small as nanometers, and the measurement range is as large as a few meters; it can be used for static measurement or dynamic measurement.

What is a level sensor?

The application of sensors in production and life has greatly helped people, and the liquid level sensor is one of the more commonly used ones. Liquid level sensor is a device used to measure liquid level. According to the method of measuring liquid level, it can be divided into contact type and non-contact type. The input type liquid level transmitter we call is a contact measurement, which converts the height of the liquid level into an electrical signal for output. It is currently a widely used liquid level transmitter.

How to choose an input type liquid level sensor?

The input measuring sensor developed and produced is a commonly used sensor on the market. The working principle of this equipment is the pressure on the liquid surface of the sensor when the liquid level sensor is put into a certain depth in the liquid to be measured. To convert the height of the liquid level, the calculation formula is Ρu003dρ.g.H+Po, where P is the pressure on the liquid surface of the sensor, ρ is the density of the measured liquid, g is the local gravity acceleration, and Po is the liquid surface Atmospheric pressure, H is the depth of the sensor into the liquid.

Water level monitoring and control
The input type liquid level sensor has no display function. If you want to view the liquid level value intuitively, you need to connect the attention display table or the digital tube display table. Use them to read the values, this method is suitable for working at a distance from the monitoring site; there is also a method that can view the data but also remotely monitor the data through the GPRS data collector to upload the data to the device through the GPRS/4G method With the environmental monitoring cloud platform, users can view data anytime and anywhere. When the liquid level is higher or lower than the warning level, the cloud platform will send an SMS alert to the user.

When using the liquid level sensor, you need to pay attention to the point that the air pipe mouth should be facing down during installation to avoid inaccurate measurement caused by water ingress. The air guide cable plays a key role in atmospheric compensation. During installation, avoid locking the air guide cable too tightly or bend it at an acute angle to prevent the air duct from being blocked and reducing the measurement accuracy. The correct installation method should be the air duct outlet Face down to prevent rainwater from clogging. When using it in a tank or tank, make sure to avoid burying or clogging the transmitter probe part due to impurities such as mud and sand.
The input type liquid level sensor is favored by users with its exquisite structure, simple adjustment and flexible installation method. It is currently widely used in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries Perform level measurement of various media.
