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 nonsymmetrical, 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 ( 
diameter with use of the small pipe 
sensor, model FD-7000-S1.
