BADGER iSonic 4000

Open Channels Ultrasonic flow meter


The iSonic 4000 is an intelligent and versatile ultrasonic meter / controller designed to measure level, volume and open channel flow.

It is used for influent and effluent measurements, flow control and data logging.

max. flow:
from 60 up to 110460 l/min
from -20 up to 60 °C
Water & waste water industry, Chemical industry, General industry

Measuring principle

Ultrasonic flow meters

Ultrasonic signals are alternately sent in and against the flow direction. Ultrasonic energy bursts are transmitted and received via well-defined paths across the flow stream. The velocity of the flow is accurately measured by the difference in the arrival times of signals from the upstream and downstream transducers. The transit time difference (Δt = t 2 – t 1) determines the average flow velocity.
