GUT742 Ultrasonic level transmitter serise contains two-wire and digital type. There are 3 models in two-wire type: Two-wire distance measurement current; Two-wire with HART and two-wire with bluetooth type. The digital type is with independent power supply (3.5V to 5V, 9V to 12V, 20V to 32V) and with MODBUS output. User could easily use Android devices / HART operator / PC for parameter setting or data reading (Except distance measurement current type). Transmitter of the product is made with single probe, which makes the whole structure compact, economical and practical.
