System description Electromagnetic flowmeters with the IFC 090 signal converter are precision instruments designed for linear flow measurement of liquid products. The process liquids must be electrically conductive: ≥ 5 µS/cm (for cold demineralized water ≥ 20 µS/cm). The full-scale range Q100% can be set as a function of the meter size: DN 2.5.- 1000 / 01/10” - 40” Q100% = 0.010 - 34 000 m3/hr = 0.03 - 151 000 US Gal/min This is equivalent to a flow velocity of 0.3 - 12 m/s or 1 - 40 ft/s.

Part C Special applications, functional checks, service, and order numbers 6 Special applications 6.1 Use in hazardous areas Electromagnetic flowmeters with IFC 090 signal converter are approved as electrical equipment in conformity with the harmonized European Standards and Factory Mutual (FM). Correspondence between the temperature classes and the temperature of the process liquid, meter size and material of the measuring tube liner is defined in the test certificate.
Stable signal outputs when measuring tube empty 6.3 Output signals can be stabilized to values as for “zero” flow to prevent random output signals when the measuring tube is empty or when the electrodes are not wetted in the event the measuring tube is partially full. - Display: - Current output: - Pulse output: 0 0 or 4 mA, see setting in Fct. 1.05 no pulses (= 0 Hz), see setting in Fct. 1.06 Precondition: electrical conductivity of product: ≥ 200 µS/cm, ≥ 500 µS/cm for meter sizes DN 2.

(change magnetic field frequency) – Stroke frequency less than 80 strokes/min (at max. pump lift): do not change setting. – Stroke frequency 80 - 200 strokes/min (at max.
Unsteady display and outputs 6.6 Unsteady display and outputs can occur in connection with – high solids contents, – non-homogeneity, – poor blending, or – chemical reactions still in progress in the process liquid. If, in addition, flow is also pulsating due to the use of diaphragm or reciprocating pumps, refer to Sect. 6.4. Operator control of the signal converter for the new settings IFC 090 B (basic version) see Sect. 6.2 IFC 090 D (display version) see Sect. 4 and 5 To change settings • Fct. 1.
6.7 HART ® for IFC 090 HART ® interface The HART interface is a smart interface, in other words a communication signal superimposed on the current output. All functions and parameters can be accessed via this interface. The following HART features are supported by the IFC 090 signal converter: • point-to-point connection • multidrop (up to 15 HART devices) The burst mode is not normally used and is therefore not supported.
Minimum load impedance A minimum load impedance of 250 Ω is required to enable the HART signals to be modulated on the current output. Series-connect an appropriate resistor if the devices located in the current output circuit should not attain this value. It will then be possible via the minimum load impedance e.g. to connect the HART communicator or smart converter in parallel without interrupting the current output. Please note that the load impedance should not exceed a maximum of 500 Ω .

Measuring principle and function of the system 11 The flowmeter is designed for electrically conductive fluids. Measurement is based on Faraday’s law of induction, according to which a voltage is induced in an electrically conductive body which passes through a magnetic field. The following expression is applicable to the voltage.
