  Description

Electronet series ASIONIC™ 100 are microcontroller-based, 2-wire, full-bore ultrasonic flow transmitters designed for a wide range of industrial applications. These transmitters accurately measure the flow rate of conductive and non-conductive liquids in closed piping systems.

With a simple and robust construction, the instrument ensures obstruction-less flow measurement and requires no mechanical maintenance, making it a reliable alternative to conventional flowmeters. The use of advanced Transit Time Technology ensures superior accuracy, generating a linear 4–20 mA DC output proportional to volumetric flow.
