Application of submersible level transmitters in liquid level measurement

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. The potential for the development of position sensors is huge now and in the future.

What is a level sensor?

Liquid level sensors are currently widely used in liquid level measurement in water plants, sewage treatment plants, urban water supply, high-rise pools, water wells, geothermal wells, mines, industrial pools, oil ponds, hydrogeology, reservoirs, rivers, oceans, etc. And play an increasingly prominent 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. Measurements are 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.

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 a submersible liquid level sensor?

Our Submersible Level Transmitter is a commonly used sensor on the market. The working principle of this equipment is that when the liquid level sensor is thrown into a certain depth in the liquid to be measured, the pressure on the liquid surface of the sensor is converted into the height of the liquid level. The calculation formula is Ρ=ρ.g.H+Po, the P in the formula is the pressure on the liquid surface of the sensor, ρ is the density of the liquid being measured, g is the local gravity acceleration, Po is the atmospheric pressure on the liquid surface, and H is the sensor input The depth of the liquid.

Water level monitoring and control

The input liquid level sensor has no display function. If you want to view the liquid level value device intuitively, you need to connect the attention display meter or the digital tube display meter to read the value. This method is suitable for working at a distance from the monitoring site; There is a way to view the data and remotely monitor the data. The GPRS data collector uploads the data to the environmental monitoring cloud platform via GPRS/4G, and the user can view the data anytime and anywhere. When the liquid level is higher than Or when it is below 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 face down when installing to avoid inaccurate measurement caused by water ingress. The air guide cable plays a key role in atmospheric compensation. When installing, avoid locking the air guide cable too tightly or bend it at an acute angle to prevent the air guide tube from being blocked and reducing the measurement accuracy. The correct installation method should be the air guide tube outlet Face down to prevent rainwater 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 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, metallurgical, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries for various media Level measurement.
