SGM LEKTRA Meter Ultrasonic Level Transmitter

Meter Ultrasonic Level Transmitter

The METER ultrasonic level transmitters are designed for level measurement in many applications including tanks closed or open, the construction materials are suitable for measuring aggressive chemicals.

There a have 4 modes possible for configuration and calibration:

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).

Via MODBUS RTU by PC interface with USB/RS485 and communication software 010F105A. Via HART, by Hand-Held, or by HART modem connected to a PC. Via smartphone Android App (only 4 wires version).

The removable display module allows its use as a fixed display or calibration module. Versions available with 2-wire or 4-wire, 2-wire with communication HART and ATEX certification, 4-wire with communication MODBUS and 2 relays.
