LEVEL

Ultrasonic Level Transmitter
Compact ultrasonic instrument with display for applications in liquids
and bulk solids.
The non-contact technology makes it ideal for installations where it is
necessary to minimize the maintenance costs.
The removable display module allows its use as a fixed display or
calibration module.
Are available versions with 2-wire or 4-wire, 2-wire with communication
HART and ATEX certification, 4-wire with communication MODBUS
and 2 relays.
