The FDT7000 Series ultrasonic flow meter is known
for it's ease of installation. The clamp-on pipe
sensors do not require pipe fittings or breaking of the line, and they do not come into contact
with the internal liquid. The technology has inherent
advantages over alternate ultrasonic devices including:
low-cost, easy installation, no pressure head loss,
no moving parts to maintain or replace, no fluid
compatibility issue, and a wide measuring range
that ensures reliable readings over liquid velocities from 0.1 to 6 metres/sec. The series is designed to work
on PVC, PP and UPVC pipe systems.
The flow meter has a powered (sourced)
4 to 20 mA analogue output which shares a common
ground with the power supply. The output transmits
a continuous current signal that is proportional to
liquid flow rate. The output is scaled at the factory; to
ensure that the instrument or data acquisition system
that is receiving the 4 to 20 mA signal responds
properly, it must be spanned identically to the flow.
