t weight:
The adoption of the latest LSI technology and plastic hous-
ing has reduced the size and weight of the flow transmitter
to one-fifth of our general use flow transmitter.
3. Superior temperature effect:
The adoption of
Sound Velocity Measurement System
permits almost no influence from fluid temperature and
pressure.
4. Quick response:
With the use of fast-speed transit time processor, the sys-
tem cycle is 0.2 sec that is applicable to short batch pro-
cess.
5. Multilingual:
The following languages are supported for display: English,
Japanese, French, German and Spanish
6. Synchronization (option):
Cross-talk between flowmeters located closely or acoustic
interference between flowmeters installed on the same
pipe line can be removed by using this synchronization
function of transmission timing of ultrasonic waves.

System configuration:
The system is composed of a detector (Model
FLS...1) and a flow transmitter (Model
FLR...1), realizing single-path system.
Application:

wave can propagate (purified water, cooling
water, corrosive liquids, cooling/heating me-
dium, etc.)
Turbidity: 10000deg (mg/L) or less
Fluid temperature:
-20 to +100deg.C With silicon rubber
for acoustic couplant
0 to +60deg.C
With silicon-free grease

This meter is a clamp-on type ultrasonic flowmeter for per-
manent use based on transit time measuring method. This
flowmeter is designed to be suitable for machine mounting,
thoroughly aimed at small size, light weight and ease of use.
This flowmeter can be applied to the pipe size from 25 to
225mm, providing the best cost per performance.
Type of flow: Well-developed turbulent or
laminar flow in a full-filled pipe
Applicable flow pipe:
Pipe size: 25 to 100mm (FLSE1) or 50 to
225mm(FLSE2) for plastic pipes
50 to 100mm (FLSE1) or 50 to
225mm (FLSE2) for metal pipes
Material: Plastics (PVC, PVDF(Note), PEEK,
PP(Note), FRP, etc.) or Metals (Car-
bon steel, SS, copper, aluminum,
etc.)
(Note)Measurement may not be
made depending on diam-
eter and thickness of the
pipe.
