6 OPERATION MFC 400 6.4 Calibration functions 6.4.1 Zero calibration (C1.1.1 Calibrate Zero) Following installation, perform zero calibration prior to commissioning the device. Finalise the installation before performing zero calibration. Changes (pipe system or calibration factor) made after the zero calibration may affect the accuracy, making it necessary to perform zero calibration again.

6 OPERATION MFC 400 6.4.2 Density calibration (C1.2.1 Calibrate Density) Mass flowmeters are calibrated for density in the factory. Density calibration is based on 2 calibration points. In the factory, air and water are used under reference conditions. The result of this calibration is saved in the signal converter electronics and stored in the factory settings. Regardless, various applications require maximum accuracy which can only be achieved with on-site calibration.
OPERATION 6 MFC 400 On-site density calibration: • Ensure that the device has been properly installed and functions smoothly. • If air (empty) is used as the medium, the measuring tube must be completely dry and free of liquids and solids. If possible, blow dry air into the measuring tube to empty it. • If liquids are used, flush for a few minutes at a high flow rate to remove gas bubbles. • Set the flow rate to a typical value (50% of the nominal flow is ideal).

OPERATION 6 MFC 400 6.5 Measurement functions 6.5.1 Flow (C1.1.0 Flow) Flow direction (C1.1.4 Flow Direction) This function allows the operator to set the direction of flow in relation to the arrow on the housing. If "Forwards" is selected, the flow direction corresponds to the "+" arrow and with "Backwards" the flow direction corresponds to the "-" arrow on the housing. Process noise damping (C1.1.5 Process Noise Damping) The flow and density measurements are filtered in order to reduce process noise.
6 OPERATION MFC 400 Pressure suppression (C1.1.7 & C1.1.8) The pressure suppression eliminates any disruption in the measurement in the event of an abrupt flow switch-off e.g. when valves are suddenly closed. In such cases, surges may occur in the pipe and in the measuring device which could lead to over-vibration. The flow then "swings" back and forth before a stable zero flow is established, as shown in the figure below. This effect occurs mainly in high pressure applications.
OPERATION 6 MFC 400 6.5.2 Density (C1.2.0 Density) Density mode (C1.2.2 Density Mode) There are 4 available operating modes for density that can be set here: • Process: The device measures and displays the current operating density of the product. • Fixed: The device displays a fixed density value. This value must be entered in menu C1.2.3. • Referred: The device calculates the density based on a set reference temperature.
6 OPERATION MFC 400 The following equation is used to calculate the density gradient: a = (ρD - ρC) / (TB - TA) The value for the density gradient is generally positive as an increase in temperature usually reduces the measured density (exception: water anomaly). Calculating the standard density The measuring device can display a density which has been corrected in terms of the standard temperature in accordance with API MPMS 11.1. The corresponding reference temperature is entered in menu C1.2.4.
OPERATION 6 MFC 400 6.5.4 Detection of 2 phase flow Due to EGMTM (Entrained Gas Management) the device performs a stable measurement function between 0…100% gas ratio. The device provides a signal which indicates two phase flow. This signal can be used for signalling two phase flow according to NE 107 or for approximating the amount of entrained gas. The signal depends on the amount, distribution and size of the entrained gas and therefore any threshold has to be adapted on the application.
6 OPERATION MFC 400 6.6 I/O configuration 6.6.1 Damp output signals All digital and analogue outputs provide damping with a digital filter which allows to stabilise the output. The damping can be individually set for each output by a time constant. However, keep in mind that the degree of filtration affects the response time of the device in the event of rapid changes.
OPERATION 6 MFC 400 6.6.3 Polarity of measurement All digital and analogue outputs provide a polarity setting which allows: Polarity Function Both Polarity function does not affect output values. Positive Positive values passed to output, negative values set to 0. Negative Absolute value of negative values passed to output, positive values set to 0. Absolute Absolute value of input values.

OPERATION 6 MFC 400 Application specific lock (C6.3.6 Write Lock Selection) Custody transfer (CT) applications require a lock for all parameters and functions which affect the relevant measurement and outputs. For this purpose the signal converter provides an application specific lock which can be enabled by a jumper. The lock mechanism can be configured before applying the jumper in order to lock only CT relevant functions and parameters.

Shows the beginning of a status event. Shows the end of a status event. Table 6-31: Symbols for the log of a status event 6.12.3 Reset errors (A2.1.0 Reset Errors) Some diagnostic functions generate latching status messages which need to be acknowledged by the operator.
