The UFS 3000…-EEx flow sensor is the d efault me as uring unit of t he UFM 3030 (3-beam)
ultra s onic flowme ters. It contai ns t he ultrasoni c s ensor (three pairs of oppos ite t r ansducers) in type
of protection intrinsic safety category "ib" according to EN 50020. All sensor circuits are wired by
separate coaxial cables and connected through SMB connectors, which are marked by the
respective numbers 1.1, 1.2, 2.1, 2.2, 3.1 and 3.2. The flow sensors are available in size DN25 (1”)
up to DN3000 (120”) in diameter.

The UFS 3000…-EEx flow sensor is used in combinati on with the fl ow co nverter un it type UFC
030…-E E x, w h ich is either dir ectl y mounte d on top of t he flow sen sor (compact me te r ) or inst al led

1.3.2 Optional instruments

The following option s are available to support c ustome rs that have one or mo re ult ra s onic flowmete r
sys te ms (in compact an d/ or sep ar at e desi gn) ba sed on the U FM 50 0…- EE x se rie s and ne ed to
replace the UFC 50 0…-EE x electr onic s unit.

Because the intrinsically safe “ib” sensor circuits of UFS 500…-EEx flow sensor have almost the
same maximum values (i.e. entity parameters) as the UFS 3000…-EEx, it can also be driven by the
UFC 030…-EE x elec tronics unit. Therefore only four of th e six SMB connectors on t he front-en d
printed circuit board of the UFC 030…-EEx electronics unit must be connected to the four SMB
connectors of t he UFS 500…-EEx flo w se ns or . For proper functioning must c onnector number 1.1,

1.2, 2.1 and 2.2 of the UFC 030…-EEx be connected to respective number 4, 3, 1 and 2 of the
UFS 500 … -EEx fl ow s enso r.

An exception applies to the ALTOSONIC V-version UFS 500 F/5STR-EEx, which can only be driven
by five UFC 50 0…-E E x electronics un its.

The intrinsically safe "ib" ultrasonic sensor circuits inside the UFS 500…-EEx flow sensor have the
same maximum values (i.e. entity parameters) as the UFS 3000…-EEx, except for the internal
capaci t anc e, w hi ch is a littl e smal l er, na mel y : Ci = 7.7 nF (maxi mu m, 2 se nso r circu it s)

1.5 Electrical data

1.5.1 Power supply unit

The UFC 030…-EEx electronics unit is equipped with a switching-mode power supply, which is
available in two supply voltage ranges, namely:

• 100…240 V AC power supply;

• 24 V AC/DC power supply.

The power s upplies are available in the standard as well as the MODIS design. The ma in diff erence
between the se ver sio ns i s that the MO DI S versio ns are not pr ovi de d with the anal o gue i npu t A 1 and
its driver logic. The +33 V o utput o f t he secondary winding of the mains transformer t hat pr ovides
the necessar y 24 V for t he analogue input driver logic is therefore not available on the MODI S
versions .

The power s upply’s mains transformer pro vi des the galvanic separation between th e primary circuit
(i.e. main s supply) an d the secondary circuits. The secondary windings o f t he mains transformer
deliver the following output voltages:

• +/- 33 V to supply 24 V to the driver logic of the analogue input A1. This analogue input is only
available on the standard (non-MODIS) versions.

• +/- 24 V for the +6 V and -6 V internal supply voltages of the electronic components of the
UFC 030…-EE x electr onic s unit.

The table below lists the electric al input voltages of the power su pply units, at the primary side of

The UFM 3030 ultrasonic flowmeters are maintenance free with regard to the flow metering
properties. Within the scop e of t he peri odical ins pections, which are re quir ed for electri c al apparatus
that is installed and used in a hazardous classified location, it is recommended to check the
flam eproof c onve rter housing on signs of corrosion and dama ges.

5.2 Replacement of electronics unit or pow er fuse(s)

The following instructions must always be carefully followed, if the flow converter
housing in which the UFC 030…-EEx is installed has to be opened respectively
closed again!

Before opening:

• Make absolu tely sure t hat th er e is no explosion hazard!

• Gas-free certificate!

• Make s ure that all connecting cabl es are saf ely i s olated from all external so ur c es!

• Allow th e pre s c ribed wai ting ti me to elapse before opening the housing: 20 minutes for

temperature class T6 and 11 mi nutes for temperatur e class T5

When the instructions above are stric tly followed, the cover (inclu des a gl ass window) of t he
electronics compartment may be removed. First unscrew the recessed head screw of the
interlocking device by a hollow-head scr ew wrench size 3, until the cover can rotate freely. Unsc re w
the cover with the special plasti c wrench (black) that is suppl ied wi th the apparatu s.

After opening:

• The c opper g ro unding s trip at t he back of the electr onics unit must be sec urely screwed to the
housing (bac k - end of electronics comp artmen t ) by scr ew C (see f igure below). The electronics
unit is screwed into the el ectronics compart men t by two screws B. Before screws B and C can
be accessed, t he display unit must be removed via screws A.

• Before the cover is screwed back into the housing, the screw-thread must be clean and well­greased with an acid and resin-free grease, e.g. silicone grease.

• Screw the cover as tight as pos s ible into t he housi ng by h and, until it c annot be opened by hand
anymore. Screw the recessed head screw of the interlocking device tight.

2)
The fuse-holder, in which the mains fuse in accordance with IEC 127-2 size Ø5 x 20 mm is

3)
mounted , is now accessi ble to replace the defect power fuse by a new fuse wit h the same
rating. The 100…240 V AC power supply (see figure 7 on the next page) is provided with a
fuse rated at T 0.8 A / 250 V, the 24 V AC/DC power supply has a fuse of T 1.25 A / 250 V
(see figure 8). The analogue input c ircuit A1 is pr otected by a su b-miniature fuse of ty pe TR 5
that are rated T 50 mA / 250 V according to IEC 127-3 publication. The MODIS versions have
the same power fuses and locations as the standard (non-MODIS) versions, but they do not
have analogue input fus es .
