> Description
The new SONIC-VIEW series flow meters offer a compact, solid
state solution for measuring flow in areas where flow sensors with
moving parts cannot be applied. Its interference free operation,
combined with a long-life cycle and the wide independence to the
inlet and outlet pipes makes SONIC-VIEW the perfect solution
even in compact machines with cramped confines.
> SONIC-VIEW series
The SONIC-VIEW series operate on the transit time principle. Two
ultrasonic transducers are positioned on the outer surface of the
measuring pipe. The advantage of this method of metering is that
the transducers will not be in contact with the medium and also
the complete absence of moving parts. These transducers are
used alternately as transmitter (T) and receiver (R). Thus the sonic
signal is transmitted in the flow direction () and reverse to the
flow direction (). The difference of both transit times (Δt) is
proportional to the average flow velocity.
