Ultrasonic level transmitter

Range 0,25-6 / 0,4-10m

IP67|68 protection

Suitable for liquids and granules

MODBUS RTU comm. protocol

Power supply 12Vdc; 20÷30Vdc; 24,115,230Vac

Output: 4 ÷ 20 mA + 2 adjustable relays


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).
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.
