The SYS-SMF is a high-precision Coriolis mass flow meter for liquids and gases. In addition to the flow, SYS-SMF also directly measures the fluid density. The SMF Coriolis flow meter was
developed for applications where maximum accuracy, a huge measuring range and highest process reliability are required.
The systec SMF flow meters are very accurate. The mass flow of liquids is measured in a huge span with the class 0.2%, 0.1% or 0.05%. The density is determined with an uncertainty of
0.1 – 0.5 g/l.
The SYS-SMF has a variety of analog and digital interfaces and can therefore be easily integrated into existing PLC.
SYS-SMF is very easy to use. Thanks to the large graphical colour display, the flow meter can be easily set up using the front buttons or with the included IR remote control through the
closed glass cap. Thanks to a selection of different corrosion resistant steels, SYS-SMF is suitable for a variety of fluids.
The Coriolis flow meter is one of the most accurate flow meters. During an extensive series calibration at the Phy si ka lisch Tech ni sche Bun des an stalt in Braunschweig (highest German
national lab of metrology), the SYS-SMF has already proven its precision: the uncertainties were down to 0.05% of the flowmeasurement value. The uncertainty of the density measurement is with 0.1 – 0.5 g/l, also highly precise and can be used as a valuable process parameter.
Coriolis meters are used where high accuracy and reliability are required. These include, for example, dosing tasks in the food industry, chemical and pharmaceutical processes or additive dosing in the hydrocarbon industries. Coriolis flow meters are also used for processes with custody transfer requirements.
Example applications:
In the SYS-SMF there are two parallel U-shaped tubes, which are stimulated to vibration in the lower part of the bend. Sensors on the flanks of the U-tubes measure the resonance
frequency and phase shift of the oscillation between the flanks. The resonance frequency depends on the weight of the two tubes and thus on the density of the liquid in the tubes. The resonance frequency is therefore a direct measure of the density of the liquid. If there is no flow, the two oscillation signals that sensor A and sensor B measure are in phase. If a fluid flows, the Coriolis force creates a phase shift between sensors A and B. This phase shift is linear with the mass flow through the pipes and is therefore a direct measure of mass flow.
The SYS-SMF Coriolis flow meters are extremely accurate. The mass flow of liquids is measured in the large measuring range with the class 0.2%, 0.1% or even 0.05% of the measured value. The density is determined with an uncertainty of 0.1 – 0.5 g/l .
As standard, the measuring devices are equipped with a factory calibration certificate delivered with a weighing test bench of class 0.02% or on a loop test bench of class 0.05%. Alternatively,
DAkkS calibration certificates with a test bench accuracy of 0.04% are possible.
To ensure the maximum accuracy in signal transmission, the SMF flow meters have not only analog but also digital interfaces to transmit the measured values digitally to the PLC.
The uncertainties of analog transmission can be avoided by using the digital interfaces. SMF flow meters are very easy to use. The large digital display allows the flow meter to be parameterised quickly and easily. Through a selection of different corrosion-resistant steels, SYS-SMF can be used for a variety of fluids.
