Software Versions
2.2.1. Basics
The standard operating software is used for all basic hardware units. The basic functions are identical for all software
versions; you can use them on all the units. Software versions are marked according to NAMUR EN53.
Examples:
MLT 6130 V1.2x 1 measuring circuit with 1 analog output and 2 limit-value outputs with relay
MLT 6230 V1.2x 2 measuring circuits with 1 analog output and 2 limit-value outputs with relay on measuring
circuit 1
MLT 6130/260 V1.2x 1 measuring circuit with 1 analog output and 2 limit-value outputs with relay
2nd measuring circuit and 2nd analog output can be activated with the activation code
MLT 6260 V1.2x 2 measuring circuits with 1 analog output each; measuring circuit 1 with to limit-value outputs
with relay on measuring circuit 1
Within each software type additional functions can be activated liable to costs.
For each additional function a separate activation code is generated for each measuring circuit. The activation code is
serial number depending.
The simple menu navigation (language selectable) assures a fast and accurate operation.
Input can be made via buttons and display of the device or via connection to a laptop or the process control system.
Basic function
The mipromex®MLT has one or two separated and independent measuring circuits. Depending on the device type,
one or two measured signal processing can be activated.
The impulse signal transmitted by the measuring electronics MTI becomes in an offset compensated, filtered impulse
value changed and into function of the entered measuring range for the batch separation with dynamic interfacial
layer detection or a parameter substitute for the interfacial layer level converted into 4-20 mA signals.
The output signal is displayed as pulses value, % value semantics on:
mm/cm/m/ml/l/hl/cm3/dm3/m3/g/kg/t/in/feet/ga/lb/oz/gt or as mA value.
The offset range can be set between 10 and 1000 pulses.
The measuring signal offset (zero point) can be picked up automatically and/or the stored value can be modified via
the keypad buttons. The measuring span is product dependent determined and automatically stored and/or the
stored value can also be modified manually via the keypad buttons. The impulses signal is converted into a 0–100%
value.
The 4-20 mA analog output from the interfacial layer measuring can spread via programmable % start value and %
final value.
Parameter input is menu-driven and device-type based. Inactive positions are hidden.
The parameters can be stored and reloaded. The device is equipped with three digital inputs which the dynamic
interfacial layer monitoring is started alternatively at batch separations or being able to dial interfacial layer level in 7
product-related parameters. If all 3 inputs are on 0, the interfacial layer monitoring can also start ID via keypad
buttons. At the interfacial level measuring the parameters are loaded from the archives.
For interfacial layer monitoring or level measuring being available 2 open collectors (OC) or relay with change-over
contact low and high function as well as adjustable at on-delay, drop-out delay and fail-save position. Error messages
are visualized with time and date of the error. Press OK button more than 2 seconds, the error is confirmed and the
display changes back to lastactive menue point.
Measuring circuit
One or two probes with the measuring electronic MTI in the connecting head are connected to the mipromex®MLt
using a shielded two core cable. Between field and control room an equipotential bond must be installed.
Function
The product-surrounded electrode system of an aquasant-mt impedance bar probe varies the impedance in function
of the dielectric and electrically conductive qualities of organic products or aqueous solutions as well as in function of
the immersion depth of the active part of the bar probe .
The measured impedance sum signal is converted directly by the measuring electronic MTI into a normed signal and
is transmitted as pulse packages to the mipromex®MLT.
