•The instrument selects the appropriate guiderail using the data entered and now displays the following. The sensor set can
be “A”, ”B”, ”C” or “D” and the mode Reflex or Diagonal.
•Take the guiderail selected by the instrument out of the case, retract the sensor blocks back into the guiderail by turning the
knurled knobs clockwise. If transducer “C” is selected and these blocks are available, remove “B” transducer set and
replace with “C” transducer set.
•Apply couplant to both sensor blocks as shown, then attach to the pipe using the appropriate mounting hardware.
•
•In most cases the guide rail selected will suit the application. The user can choose another rail and/or sensors to increase
sensitivity, signal strength or change flow range (see 3.4.1 – Select Sensor Set).
NOTE:
If the instrument has selected a guiderail assembly to work in DIAGONAL MODE the floating transducer has to be
removed and placed on the opposite side of the pipe, using the diagonal beam rail and the appropriate mounting
hardware (See 2.9 - ATTACHING THE TRANSDUCERS).
•Connect the red/blue and black sensor cables to both the electronics and the guiderail assembly. The red cable indicates +ve
flow if upstream.
•Attach to the pipe as shown in figure 3 and turning the knurled knob anti-clockwise, screw the fixed transducer to the pipe,
making finger tight contact.
•Press ENTER and the display will show the separation distance in mm.
•Set the separation distance (see figure 3) by sliding the floating transducer along the scale until the front edge of the block is
at the recommended distance. Now turn the knurled knob anti-clockwise, until in finger tight contact with the pipe surface.

2.3 Charger (only use the charger supplied)
The battery takes 15 hours to fully charge. When the instrument is charging but switched off the display will read CHARGING
and display a battery and plug symbol. When the instrument is in flow mode, the fact that the battery is charging will be
displayed under Battery. The instrument also displays a “plug” symbol when connected to the mains in flow mode.
2.4 Battery
When you first receive your unit put the battery on charge for a minimum of 15hrs. When fully charged the battery will last up
to 24hrs, depending on the outputs used and how often the back light is operated. If the backlight is enabled, every time a keyis
pressed the backlight comes on for 15 seconds. This dramatically reduces the battery life. If the backlight was on continuously
the battery life would reduce down to 8hrs, and if the 4-20mA was used constantly at 20mA, this would reduce the battery life
by 20%. The display in flow mode continually shows the battery level as a percentage. When this indication reads
approximately 20%, it will display a warning message, at which point there is only 30 minutes of use left. The battery can be
charged while the instrument is in use or overnight while the instrument is switched off. The instrument can be partially charged
and then used.
2.5 Keypad
Programming is via the tactile membrane keypad with rim embossed keys. The keypad is rated at IP65.

Press 9>m3/hr, press 9 > m3/min,
press 9>m3/sec
There are some facilities that require you to move the cursor on the display left and right as well as up and down. This is done
with keys 5(left) and 6(right).
The 4-20mA, Pulse, RS232 and logger keys can only be activated from flow mode (see page 33 - Keypad Options) but the
RS232 and data logger are also on the MAIN MENU.
2.6 Temperature indication/range
The transducers work over two temperature ranges. The standard temperature range is from -20 °C to +100 °C and high
temperature is from –20 °C to +200 °C. The application temperature is displayed when in flow mode only if the prop/temp
sensor cable is connected. If the instrument is displaying the temperature produced from the sensor in the transducer, then this
figure will vary if the temperature of the application varies, which could serve as an indication of change in the process. The
instrument can only compensate for a temperature change of ±10°C when reading flow.
2.7 Transducers
The UFM 610 P uses three different transducer types to measure flow which we call “A”, “B” and “C”. These are selected by
the instrument depending on the data entered, the pipe size and flow velocity. There are default settings that are programmed
into the instrument and most of the time these will not need to be changed, although it is possible to use different transducer sets
on different pipes outside their normal operating range. (see 3.4 Select sensor set).

12
2.7.1 Transducer set "A"
2.7.2 Transducer set "B" and "C"
NOTE:
The sensor blocks must always be placed in the guiderail as shown above. If for any reason they get taken out, it is
possible to put them back in the opposite way. This will result in the instrument not working correctly.
Transducer set “A” and transducer set “B” are positioned in the guiderail, tohelp align the transducer blocks along the pipe axis
correctly. Both the “A” and “B” guiderails have two sensor blocks. One of these is fixed, the other is moveable and can slide up
& down the scale to enable you to set the separation distance required.
The separation distance is calculated by the instrument when the application information has been entered. The fixed sensor can
be identified because it is slightly longer and has two connections as opposed to the floating block only having one connection.
Each guiderail can be mounted to the surface of the pipe using the mounting hardware provided, which includes both velcro and
webbing straps. Magnetic attachments are available as an option with guiderail “B” and the diagonal guiderail, “D” sensors are
supplied with ratchet straps.
2.7.3 Transducer set "A"
These are supplied for pipes 13mm to 89mm inside diameter. They are only supplied with velcro straps, unless the high
temperature version has been supplied. Magnets are not available for this transducer set.

2.7.4 Transducer set "B" and "C"
There are two types of transducer block available that both fit into guiderail “B”. One pair for standard velocity on pipes 90mm
to 1000mm, the second pair “C” are for higher velocity flow in pipes 300mm to 2000mm inside diameter. Magnetic attachments
are available to fit onto these guiderails as a standard they are supplied with chains.
2.7.5 Transducer kit "D"
The “D” transducers are for use on pipes 1000 mm to 5000 mm inside diameter. The sensors are supplied with their own guide
rails, ratchets and webbing straps. They may also be supplied with chains if required, if webbing straps have been supplied with
the standard instrument they also can be used to attach to the “D” guide rail. The “D” sensors are aligned in the same way as
other transducers i.e. in Reflex or Diagonal mode and the separation distance is taken from the front edge of the block as shown
in figure 12. the transducers are made from a perspex material with an operating range up to +80°C. Please state when ordering
“D” sensors whether you were supplied with webbing straps or chains with your original UFM 610 P.
2.8 Separation distance
The separation distance is calculated by the instrument when all the parameters have been entered in and the fixed transducer
has been turned down onto the pipe surface. The next stage is to slide the moveable sensor to the separation distance required
and screw down onto the pipe surface making sure not to overtighten as it may force the fixed sensor off the pipe wall - finger
tight is sufficient! The separation distance is the distance between the front face of each sensor block. See Figures 9, 10, 11, 12
pages 12 & 13, for examples in both reflex and diagonal mode. Connections are made via the LEMO IP65 connectors between
the sensor block and the electronics.
2.9 Attaching the transducer
The guiderails are attached to the pipe surface as shown in Figures 9, 10, 11 and 12 using velcro, webbing straps, chains or
magnets.

2.10 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.
2.11 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.
