FDT7000 Series ultrasonic flow meter is known
for easy installation with its snap-clamp on pipe
transducer body sensors do not come in 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 from 0.3 to 19 feet/sec
(0.1 to 6.0 m/sec). The series is designed to work
on PVC, PP and UPVC pipe systems.
The flow meter is equipped with a ground referenced
4 to 20 mA output—the output shares a common
ground with the power supply. The output transmits
a continuous current output that is proportional to
liquid flow rate. The output was 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.
The 4 to 20 mA output is designed to source current
across a loop resistance that is typically located within
a data acquisition system or other receiving
instrument. The maximum resistance that the flow can
accommodate is directly related to the DC power
source that is powering the flow meter and the
4 to 20 mA loop.
