1.3 Flow sensor
1.3.1 Standard instruments
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
on a d istanc e and c onnected via a cable (s eparate ve r s ion). In t he last c as e the flow sensor as well
as the fl ow conve rt er uni t ar e bot h provided w i th a jun ct i on box, in wh ic h the SM B connectors are
mounted.
The UFS 3000 F/ … -EEx flow se ns or in separate design is the mea s uring unit of the s eparate
flow met e r sys te m. T h ere is a stan da rd versi on, sui ta bl e fo r proce ss li qu id t emp eratu r es f rom - 25° C
up to 180°C and an extended te mp eratur e (XT ) versi on UFS 3000 F/XT-EEx, wh ic h allows a
maximum process temperature of 220°C. Both versions are designed for an ambient temperature
in the rang e of -40°C up t o +65°C.
The UFS 30 00 F/…-EEx flow sensors i n se pa rate design are classified according to the
temperature classification table below.
Temperature class

The UFS 3000 F/ … -EEx flow se ns ors are marked with th e explosi on safety cod es :
• Standard UFS 3000 F-EEx: II 2G EEx i b IIC T6…T3
• XT-version UFS 3000 F/XT-EEx: II 2G EEx ib IIC T6…T 2

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)
The UFS 500-EEx as part of th e UFM 500 K…-EEx compact flow me ter is appro ved under number
PT B 01 ATEX 2015 X and the UFS 500 F/… - E Ex fl ow sen s or wi th a separ ate design has app roval
number PTB 01 ATEX 2012 X. See Appendix 1.
1.4 Flow converter
The UFC 030… -EE x flo w convert er co n si sts of an appro ved c y l in dri cal hou si ng, made of a diecasted aluminium alloy (type AX/P/…-EEx with KEM A No. E x-99 .E.8128 U) or of stainless st eel
(type VX -EEx wi th PTB No. Ex -9 6.D.10 68 U). It contai ns two separa te compart m ents, divided from
each other by wall with an integrat ed enc apsulated flameproof termina l feed-through. The ho us ing
of the compact version is screwed on top of the flow sensor, the housing of the separate version is
screwed on an alum inium or s t ainless steel wall-mou nting brac k et. A junction box m ade of diecasted al umi ni um alloy or stainless steel is screwed to the side of the bracket by four M6 recessed
head screws with internal hexagonal socket set (on l y applicable for the flow converter in sepa rate
design).
The flow converter housing is on both ends closed by a threaded cylindrical cover with O-ring
seali n g. Coaxi a l ca bles of typ e RG17 9 or RG31 6 w i th SM B plug s at t hei r end s conne ct th e
intrinsically safe sensor output circuits of the flow converter to the corresponding SMB male-to-male
bulkheads in the junction box.
The equipotential b ondin g c onductor is scr ewed unde r t he ext ernal M 5 U-clamp terminal , which is
located on the mounting flange at the bottom of the neck of the flow converter housing. The flow
converter housing has an ingress protection degree of at least IP67 in accordance with EN 60529.
1.4.1 Electronics compartment
The elec tronic s c om partm ent acc ommodates the UFC 030…-EE x elec tronics unit . The c om partment is designed with type of protection flameproof enclosu re "d" in accordance with EN 50018. I t is
closed by a flameproof display cover with glass window, which is glued and additionally mechanical
support e d by a screwed in ba ck-u p rin g made of alu min u m or stai nl e ss ste el (dep ends on the
materi al of t he hou si ng ). The in terc onne ct i ng part (i. e. ne ck) at t he bot tom of the housin g contain s a
flam eproof c able feed-through, t hr ough which the c oaxial cables r un. T he feed-through pro vi des a
flam eproof s ealing at the bo tt om of the electronics com partme nt.

The UFC 030…-EEx electr onic s unit is inse rted into t he electr onics com partment with the he lp of
two slid ing rubb er s that position and fixate the unit at the front of the insi de of th e housi ng. Two M4
screws mount th e unit and a t hird M4 screw fixat es the br ass earth s trip at t he back-end of the fron tend printed circuit board, which contains the integrated voltage/current limiting circuit. The three
screw s are screw e d to t he integ rat ed wall ins id e the el ec tron ics comp a rtm ent. T he on t he front -end
PCB integrated voltage/current limiting circuit provides the ultrasonic sensors inside the flow sensor
with type of protection intrinsic safety category "ib" according to EN 50020.
The voltage/current limiting circuit has the following maximum output values:

1.4.2 MODIS electronics units
The MODIS electronics units have type designation UFC 030i-EEx and are provided with two
MODIS modules. The modules provide intrinsically safe signal input/output circuits, which are
accessible by the user for connection in the terminal compartment of the flow converter housing.
Thr ee typ es of modu l es can be used on the UFC 030i -E Ex el e ctr onic s un it , na mel y : P-SA (cu rrent
output), F A-ST (puls e or sta tus output ) and F-PA (fieldbus type Prof ibus).
A combination of two of the above listed modules is installed on the power supply printed circuit
board of the MODIS versions of the UFC 030…-EEx electronics.
1.4.3 Terminal compartment
The termi nal co mp ar tment accommodates s even M4 clamp termi nals for connection of the powe r
supply and the signal in-/output circuits . The termin als are separated from each other b y in s ulati on
plates (eight i n total, from which one at each en d of the row).
The terminal compartment (default in type of protection increased safety “e”) is standard equipped
with two metal cable glands of size M20x1.5 or Pg13.5. The terminal compartment can optionally be
provided as a flameproof encl os ure “EEx d”, in which c as e the custome r m us t use pre-certified
“EEx d” cable glands or conduits.
For flameproof c onduit systems, the terminal compartm ent must have type of protection fl am eproof
enclosure “d ” ac cordi ng to EN 5001 8. T he cond uits m ust be s ealed by “EEx d” approved (in
accordance wit h ATEX 100a directive) sealing d evices (i.e. stopp in g boxes) direct ly at the conduit
entrances of the as flameproof enclosure “EEx d” performed terminal compartment.
1.4.4 MODIS terminal design
The con ne ct ions for the intrinsically safe MODIS input/output circuits consist of four M 4 U-clamp
terminals, separated from the two power supply terminals by an earthed metal plate, which is
screwed to a non- us ed M 4 U- c lamp termi nal. Eight dividing plates of insulating material in-b etween
the seven terminals and at each end of the row separate the terminals from each other and from the
earthed metal housing.
After the power s upply cabl e is c onnected to the ap pr opriate two terminals, these two t er minals a re
covered by a semi-circular i nsulating pl ate to p revent any possibl e contact w ith the intrinsical ly safe
MO DI S con du ct ors. S ee f i gure below .
