GENERAL CHARACTERISTICS
• The SE_1586E2 set includes 2 probes placed in a graduated slide or ruler (central zero) .
• Connected to a device from MINISONIC/ DigiSonic / UF 322 families, it permits to measure
actual flow of pure liquids (demineralised water, hydraulic oil …) or few loaded liquids as
cooling or heating water, petrochimical products …
• This 1586E2 set doesn’t bring any pressure drop and is not affected by the pressure or the
aggressivity of the fluid .
• An accurate flow measurement is available and displayed in both directions .
• SE_1586E2 can be used on pipes from 12 mm (*) up to 114,3 mm (4’’) with its support .
(*) This limit depends on the pipe material , thickness and condition.
Pipe materials : steel (not corroded) , stainless steel, copper , plastics …
• Maximum temperature for a continuous use :120°C (above : please refer to <strong>Ultraflux</strong> ) .
OPERATION MODE
• Both probes are placed on a same generatrice and dialog in "réflex" (V) mode.It results a
good accuracy and low sensivity to hydraulic disturbances.
• For very small pipes , the “ W “ mode can offer a better result.

PROBE LOCATION
• When possible, locate probes upstream from a hydraulic disturbance..
• When possible, respect following minimum straight length :
10 Ø upstream
3 Ø downstream, Ø means diameter of the pipe .
• In the case of an horizontal pipe, avoid installing the probes
on the top or the bottom part of the pipe because the
risk of bubbles or deposits
On a vertical pipe, there is no restriction for probe location.
• Requested accuracy on distance inter-probes : +/- 0,5 mm
• The converter calculates and displays this distance D.S to be adjusted between probes
around the central zero (see fig 1).
PROBES INSTALLATION
• Clean upthe pipe (rust, roughness). In most cases, the paint doesn’t matter .
• Apply plenty of coupling agent on probes face and on the pipe wall at the location .
- Standard coupling gel for temperatures lower than 60°C (during a few hours).
- High temperature special grease for temperatures up to 120°C or long term use .
- Coupling elastomer, coated on both faces with special grease, for very long term use. It
must be hardly tight.
• The fixing is done by stretching the elastic around the pipe, or with stainless steel straps for
fixed installation (see fig 1).
CONNECTIONS
• The probe holder is equipped of two push-pull connectors for twinax shielded cables.
• Use the cables recommended by ULTRAFLUX.
• Connect upstream and downstream transducers to converter using corresponding inputs .
COMMISSIONING
• A good installation in good site condition must give a good echo signal and a reliable
measurement result.
• If the acoustic transmission result through the pipe is too poor (no echo or too high
amplification gain), proceed as follows :
- Check the distance D.S .between probes .
- Check the coupling agent between the probes and the pipe .
- If fault persists, try at another location (pipe internally corroded ?).
- If no result, try with lower frequency transducers .
- If liquid is flowing bubbles, try to improve these conditions.
