Ultrasonic level transmitter

Range 0,25 ÷ 6 m / 0,4 ÷ 10 m


Suitable for liquids and solids


Power supply 20÷30Vdc; 12 Vdc

Output 4 ÷ 20 mA (2 wire version); 4 ÷ 20 mA + 2 relays set (4 wire version)


Remote control via Smartphone


The METER ultrasonic level transmitters have 3 modes for configuration and calibration:

  1. by means of the configuration module VL601 which can be switched on and off on the METER (VL601 module is equipped with large LCD matrix display).
  2. via MODBUS RTU by PC interface with USB/RS485 and communication software 010F105A
  3. via smartphone Android App (only 4 wires version).

TThe 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.
