Ultrasonic couplant
Ultrasonic couplant must be used on the sensor face to interface with the pipe wall. (See Figures 20, 21 & 22).
On applications
above 100
°
C high temperature couplant will be required, and is supplied as standard with high temperature sensors.

Fluid types
The type of fluids that can be measured with the UFM 610 P are clean liquids or oils etc. that have less than 3% by volume of
particulate content. Liquids that are cloudy, like river water, effluent etc. can be measured and also liquids that are clean, like
demineralised water. During the set up procedure the user is asked to select from a list of liquids (See fluid type 3.2) which
includes water and oils. If the liquid to be measured is not listed it is possible for the instrument to measure the propagation rate
automatically, but only when pipes sizes are greater then 40 mm internal diameter (See 6.5). Applications include :- River water,
Seawater, Potable water, Demineralised water, Treated effluent, Water/Glycol systems, Hydraulic systems and Diesel oil.
