Principles


The working principle of Submersible Liquid Level Transmitter, also called hydrostatic level meter, level transmitter, liquid level sensor, etc., is based on the conductive nature of the liquid. When the measuring probe is partially or fully immersed in the liquid, the liquid forms a circuit with the probe. By measuring changes in resistance or capacitance, the Liquid Level Transmitter is able to determine the level height of the liquid.

With the reliable amplified circuit and precision temperature compensation, to transfer the gauge or absolute pressure of measurement medium to standard voltage or current signal.

This product comes with compact profile, easy to install, it can measure the level height directly when through into the liquor.

Features


Submersible Liquid Level Transmitter features


  1. Applicable media: can measure oil, water and paste compatible with 316 stainless steel, with a certain degree of corrosion resistance.

  2. Measuring range: 0 ~ 600kPa...60MPa

  3. Max measure range up to 200 meters or more

  4. High Stability, provide, 0.2, 0.5 accuracy for option. 

  5. Overload capacity: 3 times of the rated range

  6. A variety of output signal options: input level meter can output a variety of standard signals, such as 4-20mA; 4-20mA + HART; ModBus RS485, etc., to facilitate the user to choose according to need.

  7. Direct input structure, easy to install and use, can adapt to a very small installation space.

  8. High accuracy and good stability. In the use of temperature range of the comprehensive temperature drift, non-linear fine compensation, so in the use of temperature range of non-linearity is small, good temperature stability.

  9. No moving parts, high reliability, long service life from water, oil to the viscosity of the paste can be measured with high precision, not subject to the measured medium blistering, deposition, the influence of electrical characteristics.

  10. High protection level: sensor IP65, probe IP68.

Define your Measurement Needs

In the selection process, first of all, you need to clarify your measurement needs. This includes the measurement range, measurement accuracy, measurement medium, ambient temperature, working pressure and other factors. Through the comprehensive consideration of these factors, we can screen out the level meter models that meet the requirements.

Selecting the Right Sensor Type

The sensor types of Submersible Liquid Level Transmitter are mainly piezoresistive, capacitive, vibrating string type and so on. Different types of sensors have different characteristics, such as measurement accuracy, stability, response time and so on. When choosing a sensor type, you should weigh the actual needs and the measurement environment.


Application


  • Water tank level measurement and control.

  • Fuel tank level measurement and monitor (diesel, gasoline, kerosene and so on).

  • Liquid level measuring in tank, rivers, lake, sea, well, tube, underground water and so on.

  • Special occasion such as high temperature liquid (up to 100 degree C), strongly corrosion liquid level measurement (request by customized.)
