System Components General information The UFM 3030 ultrasonic flowmeters in compact and separate design are in accordance with the European Directive 94/9 EC (ATEX 100a) and approved for hazardous classified locations of Zone 1 and 2 by the PTB conform to the European Standards of the EN 500xx series, approval number: PTB 03 ATEX 2021 X. -
Page 7: Flow Sensor
Flow 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. -

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. - Page 9 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 front- end printed circuit board, which contains the integrated voltage/current limiting circuit.

Page 11: Electrical Data
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 supplies are available in the standard as well as the MODIS design. The main difference between these versions is that the MODIS versions are not provided with the analogue input A1 and its driver logic. - Page 12 (close to the local display unit). The connections are established during the installation of the IFC 030…-EEx electronics unit inside the flameproof electronics compartment of the flow converter housing by KROHNE Altometer personnel. 1.5.3 In-/output circuits The analogue input circuit A1 is protected against overcurrent by a fuse of type TR5 No.

Namur NE 43 settings The UFM 3030…EEx and UFC 030…EEx can be set-up such that the Current Output functions are according to Namur NE 43. This means the current will go either to 3.6 or to 21.5 mA (failure value can be user defined, normal operating limits are between 3.8 and 20.5 mA) in case the instrument indicates a failure. -
Page 26: Service And Maintenance
Service and maintenance Introduction Contact your nearest local KROHNE representative for ordering information of the UFC 030…-EEx electronics units and/or fuses. The UFM 3030 ultrasonic flowmeters are maintenance free with regard to the flow metering properties. Within the scope of the periodical inspections, which are required for electrical apparatus that is installed and used in a hazardous classified location, it is recommended to check the flameproof converter housing on signs of corrosion and damages. -
