What is a Level Sensor and Transmitter?


Level transmitters and level sensors are designed to monitor liquid levels in tanks, pipelines, and other process systems. Generally, they can be classified into two types: submersible level sensors and contactless level sensors. MicroSensor offers solutions for both types.

Submersible level sensors and transmitters provide continuous liquid level measurements by sensing the hydrostatic pressure generated by the height of the liquid above the sensor. They deliver output in the form of analog or digital signals. On the other hand, contactless level sensors employ radar or ultrasonic technology to measure liquid levels without direct contact, ensuring accurate and reliable readings.



Major Applications and Suitable Level Sensors


The main media MicroSensor level sensors and transmitters can measure is water, oil, diesel, chemicals, etc. 

MicroSensor level sensors and transmitters are widely used for the liquid measure and control in petroleum, chemi-industry, power station, agriculture, city water supply, drainage, and hydrology.  

Besides level sensors, MicroSensor offers water pressure sensors that can be used for water pressure measurement.



What is the Most Significant Advantage of Submersible Level Transmitters?


1.Utilizing corrosion-resistant materials and firm structure, so as to operate under high pressure, high temperature and high corrosiveness conditions.

2.Directly contact the liquid due to the sealed waterproof design, so that proving reliable and accurate liguid level measurement.

3.Small size, easy to installion and calibrarion.



How to Choose the Most Suitable Liquid Level Transmitter?


• Liquid Type: Different liquid types have different requirements for materials of transmitter. For example, the acid liquid require anti-corrosive materials. However, the high-temperature liquid require high-temperature resistant materials. Therefore, such as viscosity, density, corrosiveness, and temperature before choosing the transmitter.


• Accuracy and Stability: These are the critical specifications of the liquid level transmitters, ensuing the stable operation and process connection. 


• Measurement Range: Different liquid level transmitters have varying measurement ranges. If the selected transmitter's measurement range does not match the actual requirements, it is impossible to accurately measure the liquid level. Therefore, it is necessary to choose a transmitter with an appropriate range to ensure accurate readings.


• Output Signal and Communication Protocol: Some applications require analog signal output, such as 4-20mA or 0-10V, while others require digital signal output, such as RS485 or Modbus. Moreover, some applications require liquid level transmitters to have remote monitoring and control capabilities, so as to support for certain communication protocols, such as HART. Therefore, the output signal and communication protocol need to be considered when selecting a liquid level transmitter. It aims to meet the actual requirements.


• Installation Conditions: Available space, and installation options also need to be considered. Because some transmitters require specific installation methods or configurations, which may impact your selection.


Cost: Identify your core needs before selecting, reducing the cost as soon as possible.


By carefully assessment these factors, you can choose the most suitable liquid level transmitter for your specific application, ensuring accurate and reliable measurement and optimal process control. If you have any questions, please feel free to consult Micro Sensor at any time.



What are the Typical Applications of Level Transmitters?


Water Treatment: Level transmitters are used to water level monitoring, flow controling and liquid level alarming. 


• Oil and Gas Industry: Level transmitters are used to monitor and control the liquid levels in oil tanks, natural gas tanks, separators, and other containers in oil and gas industry.


• Food and Beverage Industry: Level transmitters are used to monitor and control the liquid levels in storage tanks, fermentation tanks and transmission pipelines in food and beverage industry.


These are just a few instances among various applications. Level transmitters exit in people’s daily life everywhere, which sustain the normal operation of many industries.
