1.3Flow sensor
1.3.1 Standard instruments
The UFS 3000…-EEx flow sensor is the default measuring unit of the UFM 3030 (3-beam) ultrasonic flowmeters. It contains the ultrasonic sensor (three pairs of opposite transducers) 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 combination with the flow converter unit type UFC 030…-EEx, which is either directly mounted on top of the flow sensor (compact meter) or installed on a distance and connected via a cable (separate version). In the last case the flow sensor as well as the flow converter unit are both provided with a junction box, in which the SMB connectors are mounted.
The UFS 3000 F/…-EEx flow sensor in separate design is the measuring unit of the separate flowmeter system. There is a standard version, suitable for process liquid temperatures from -25°C up to 180°C and an extended temperature (XT) version UFS 3000 F/XT-EEx, which allows a maximum process temperature of 220°C. Both versions are designed for an ambient temperature in the range of -40°C up to +65°C.
The UFS 3000 F/…-EEx flow sensors in separate design are classified according to the temperature classification table below.

The UFS 3000 F/…-EEx flow sensors are marked with the explosion safety codes:
•Standard UFS 3000 F-EEx: II 2G EEx ib IIC T6…T3
•XT-version UFS 3000 F/XT-EEx: II 2G EEx ib IIC T6…T2
The intrinsically safe "ib" ultrasonic sensor circuits inside the UFS 3000…-EEx flow sensor have the following maximum values (i.e. entity parameters):
•Maximum input voltage : Vmax = 13.1 V
•Maximum input current : Imax = 600 mA
•Maximum internal capacitance : Ci = 13.1 nF (maximum, 3 sensor circuits)
•Maximum internal inductance : Li = 134 µH (maximum, 3 sensor circuits)
The intrinsical safe sensor circuits of the UFM 3030 K/…-EEx compact flowmeter are only internal circuits and not accessible for the user.

1.3.2 Optional instruments
The following options are available to support customers that have one or more ultrasonic flowmeter systems (in compact and/or separate design) based on the UFM 500…-EEx series and need to replace the UFC 500…-EEx electronics 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…-EEx electronics unit. Therefore only four of the six SMB connectors on the front-end printed circuit board of the UFC 030…-EEx electronics unit must be connected to the four SMB connectors of the UFS 500…-EEx flow sensor. For proper functioning must connector 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 flow sensor.
An exception applies to the ALTOSONIC V-version UFS 500 F/5STR-EEx, which can only be driven by five UFC 500…-EEx electronics units.
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 capacitance, which is a little smaller, namely: Ci = 7.7 nF (maximum, 2 sensor circuits)
The UFS 500-EEx as part of the UFM 500 K…-EEx compact flowmeter is approved under number PTB 01 ATEX 2015 X and the UFS 500 F/…-EEx flow sensor with a separate design has approval number PTB 01 ATEX 2012 X. See Appendix 1.
1.4Flow converter
The UFC 030…-EEx flow converter consists of an approved cylindrical housing, made of a diecasted aluminium alloy (type AX/P/…-EEx with KEMA No. Ex-99.E.8128 U) or of stainless steel (type VX-EEx with PTB No. Ex-96.D.1068 U). It contains two separate compartments, divided from each other by wall with an integrated encapsulated flameproof terminal feed-through. The housing of the compact version is screwed on top of the flow sensor, the housing of the separate version is screwed on an aluminium or stainless steel wall-mounting bracket. A junction box made of diecasted aluminium alloy or stainless steel is screwed to the side of the bracket by four M6 recessed head screws with internal hexagonal socket set (only applicable for the flow converter in separate design).
The flow converter housing is on both ends closed by a threaded cylindrical cover with O-ring sealing. Coaxial cables of type RG179 or RG316 with SMB plugs at their ends connect the intrinsically safe sensor output circuits of the flow converter to the corresponding SMB male-to-male bulkheads in the junction box.
The equipotential bonding conductor is screwed under the external M5 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 electronics compartment accommodates the UFC 030…-EEx electronics unit. The compartment is designed with type of protection flameproof enclosure "d" in accordance with EN 50018. It is closed by a flameproof display cover with glass window, which is glued and additionally mechanical supported by a screwed in back-up ring made of aluminum or stainless steel (depends on the material of the housing). The interconnecting part (i.e. neck) at the bottom of the housing contains a flameproof cable feed-through, through which the coaxial cables run. The feed-through provides a flameproof sealing at the bottom of the electronics compartment.
8 |
UFM 3030 |
The UFC 030…-EEx electronics unit is inserted into the electronics compartment with the help of two sliding rubbers that position and fixate the unit at the front of the inside of the housing. Two M4
screws mount the unit and a third M4 screw fixates the brass earth strip at the back-end of the frontend printed circuit board, which contains the integrated voltage/current limiting circuit. The three screws are screwed to the integrated wall inside the electronics compartment. The on the 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:
•Maximum output voltage : VO = 8.15 V
•Maximum output current : IO = 220 mA
•Maximum allowed external capacitance : CO = 1.3 µF
•Maximum allowed external inductance : LO = 0.5 mH
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. Three types of modules can be used on the UFC 030i-EEx electronics unit, namely: P-SA (current output), FA-ST (pulse or status output) and F-PA (fieldbus type Profibus).
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 terminal compartment accommodates seven M4 clamp terminals for connection of the power supply and the signal in-/output circuits. The terminals are separated from each other by insulation plates (eight in total, from which one at each end 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 enclosure “EEx d”, in which case the customer must use pre-certified “EEx d” cable glands or conduits.
For flameproof conduit systems, the terminal compartment must have type of protection flameproof enclosure “d” according to EN 50018. The conduits must be sealed by “EEx d” approved (in accordance with ATEX 100a directive) sealing devices (i.e. stopping boxes) directly at the conduit entrances of the as flameproof enclosure “EEx d” performed terminal compartment.
1.4.4 MODIS terminal design
The connections for the intrinsically safe MODIS input/output circuits consist of four M4 U-clamp terminals, separated from the two power supply terminals by an earthed metal plate, which is screwed to a non-used M4 U-clamp terminal. Eight dividing plates of insulating material in-between 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 supply cable is connected to the appropriate two terminals, these two terminals are covered by a semi-circular insulating plate to prevent any possible contact with the intrinsically safe MODIS conductors. See figure below.
