Product Description


This series Shanghai factory 4-20ma diesel fuel tank level sensor can be used to measure & control liquid pressure in :

  • Level measuring
  • Building automation
  • Ocean and ship
  • Vacuum equipment
  • Constant pressure water supply
  • Metallurgy, environment protection
  • Medical treatment and etc.


1. WP311 Immersion level transmitters (also called static level transmitter) adopt advanced imported           sensitive component with anti-corrosive diaphragm, the sensor chip was put inside a stainless steel          (or Teflon) shell.

2. The function of iron cap at the top is protecting transmitter, and the cap can make the measured liquid      touch the diaphragm smoothly.

3. A special vented cable was used, and made the back pressure chamber of diaphragm connect well       with atmosphere, and level measurement was not varied according to the change of external                     atmospheric pressure.

4. With exact measurement, long term stability, excellent seal and corrosion proof, this transmitter meets      the standard of ship, and it can be thrown directly in water, oil and other liquids for a long time.

5.  Special internal construct technology completely solved the problem of condensation and dewfall

6.  Special designed electronic technology basically solve the problem of lightning strike


Shanghai factory 4-20ma diesel fuel tank level sensor :  

*  Imported sensor component

*  Various output signal
