Descrição
The FD-7000 Series has been discontinued. Please see the FDH-1 Series as a possible alternative or contact our Flow Engineering Department.
Up to now, doppler
ultrasonic flowmeters have required
significant quantities of suspended
particles or gas bubbles to reflect
sound signals. Now, with the model
FD-7000 ultrasonic flowmeter, this
is no longer required. When the
FD-7000 is used to measure the
flow of liquids containing suspended
solids or bubbles, the transducers
are mounted on a straight run of
pipe in the same manner as other
ultrasonic meters. In applications
where insufficient "reflectors" exist
(a condition indicated by a low
reading on the FD-7000°s flow
analyzer bar graph), the transducers
are relocated to a point in the piping
where non-symmetrical hydraulic
turbulence will be present.ideally
just downstream of a 90° elbow.
The FD-7000's unique digital filtering
system and signal recognition
circuitry transforms the reflections
from this non-symmetrical, and not
necessarily linear, turbulence into a
useable and linear data format.
A backlit, 2 line by 20 character,
alphanumeric LCD offers simultaneous
flowrate and totalizer displays.
The FD-7000 is designed for ease
of use in the field. Only a few simple
keypad entries are required to
configure the flowmeter for any
given pipe and flow conditions.
The encapsulated, submersible
design of the transducer sensor
head allows it to be easily mounted
to the pipe surface with the coupling
compound and elastic bands that
are supplied with the unit. A 6 m (20')
retractable cable for connection to
the transmitter/indicator unit is
supplied as as integral part of the
sensor. The FD-7000 sensor is
utilized on pipes that range in
internal diameter from 25 mm to
1.5 m (1 to 60").
Flowrates can be measured in smaller
pipes from 6 to 25 mm (¼ to 1") in
diameter with use of the small pipe
sensor, model FD-7000-S1.
