With ultrasonic pulses propagated diagonally
between the upstream and downstream sensors
mounted on the exterior of the pipe, the flow rate
is measured by detecting the time difference
caused by the flow.

Calculates the thermal energy received and sent with liquid (water)
in cooling and heating.
1) It can be easily mounted on the exterior of a pipe, helping reduce
mounting cost.
2) As a sensor, it can operate without coming into contact with fluid, so the
fluid is not affected by metallic ions.

*1) Normally select silicone rubber as acoustic coupler. Silicone rubber in tube (100g)
is furnished. If you place an order for several units, 1 tube may suce for every 5
units.
Select silicone -free grease for semiconductor manufacturing equipment or the
like that is vulnerable to silicone. The silicone-free grease is water-soluble and ,
therefore, cannot be used in environment exposed to water or on piping subjected
to a condensation. Since the grease does not set, a periodic maintenance
(cleaning, relling every about 6 months at normal temperature) is necessary.
* 2) It is selectable only for FS SC type and FSS E type.
