RF capacitance liquid level transmitter


TC6 series smart RF capacitance liquid level transmitter takes the advanced digital RF measure technology and micro-processor as the core, matched with IC circuit, surface mounting, and strict process flow. The meter has some advantages such as high precision, good stability, strong anti-jamming. TC6 series uses sealed structure to be waterproof, explosive proof, anti-corrosive, suitable for wild all-weather field. Other advantage includes widely application to work in environment or medium of high temperature and pressure, strong corrosion. The relative mediums include liquid, powder, or granular medium such as acid, alkali, salt, oil, water, wastewater, chemical material, manufactured feed, grains, coal dust, cement, flour, etc. it can be used widely to level automatic measurement system in petroleum, chemical industry, power generation, food, water treatment, metallurgy, cement factory, and so on.

TC6 series have kinds of function configurations through three buttons in enclosure and LCD , two points calibration in field can re-calibrate to create simple installation and debug. The parameters to be configurated include units, showing upper/lower level limit, damping, upper/lower limit of calibration, D/A correction, restore factory default, etc.


  *two-wire system, high accuracy and stable, temperature drift

  *two points re-calibration brings simple correction

  *good redurance of high temperature and pressure, strong acid and alkali , anti-corrosive as well

  *multi-function LCD indicator

  *The whole explosion proof design, explosion proof screws lock cover

  *Meter case can rotate 360°,install easily
