RBHEF-LC: Low Conductivity MagMeter

Ultra- low conductivity Magmeters EMF
  • Ultra- low conductivity Magmeters EMF

The measurement technology for ultra-low conductivity media breaks through the requirements of electromagnetic flowmeters for the conductivity of media and has been successfully applied to media with a conductivity as low as 1μS/cm. 

 RBHEF-LC Low Conductivity Electromagnetic Flowmeter is specially designed for measuring  the flow rate of low-conductivity liquids (such as pure water, deionized water, organic solvents, etc.), breaking through the high requirements of traditional electromagnetic flowmeters for dielectric conductivity.

 Using high-frequency excitation technology and intelligent signal processing algorithms to ensure high-precision measurement under extremely low conductivity conditions as low as 1 μS/cm, it is widely used in high-clean industries such as semiconductors, pharmaceuticals, food and beverages.

The RBHEF-LC Series is specifically engineered to overcome the limitations of standard EMFs, providing reliable performance for fluids with conductivity as low as 1 μS/cm.
