Submersible Liquid Level Transmitters
MPM426W Series Submersible Level Sensor

Fuels, lubricants, chemicals, pesticides, and some specific aqueous solutions in industrial production or transportation trade systems are transferred by storage tanks, so it is essential to hold environmental information (position, temperature, liquid level, pressure, etc.) of the tanks in the whole system.

MPM426W Series submersible liquid level transmitters, developed and produced by Micro Sensor, belong to the effective tools for stable, accurate, and real-time monitoring of liquid level, pressure, and temperature in storage tanks. MPM426W Series will greatly benefit users who require efficient inventory management, goods transportation, remote monitoring, and overflow prevention through intelligent design and optimization.
