  • Page 2: Installation Precaution

    SGM-LEKTRA developed the MTU5 unity to best meet the “GENERAL-PURPOSE” application requests. The MTU5 unit offers, together with its compact size, a complete versions range that makes the MTU5 very versatile for the most varied applications, including areas with explosion hazard and chemically aggressive environments. MTU5 is an ultrasonic level transmitter, temperature-compensated and suitable for connection with MODBUS RTU acquisition systems.
