Multivariable Transmitter, SYS-MMF and SYS-MTF

The SYS-MMF cost efficient multivariable transmitter for mass flow measurement using the differential pressure method. In addition to the differential pressure, the transmitter internally measures the static pressure p1 and has a PT100 3-wire input to compensate the fluid temperature.

The SYS-MMF can be completely setup very quickly and easily by means of a simple parameterization using the three front keys. Complex parameterization software is not required for this. The SYS-MMF is a 2-wire 4..20mA transmitter (HART-capable) as standard. An additional Modbus interface is available as an option.

The SYS-MMF can be used for gases, saturated and superheated steam and for liquids.

The SYS-MTF type has only a differential pressure sensor and a temperature input (no AP sensor), so it can be used e.g.  for saturated steam, or if the pressure in the application can be assumed to be constant.

In combination with the a DF25, the SYS-MMF is a particularly effective time and money saver. Install a completely Pressure and Temperature compensated mass Flow measurement via a single stud in the pipe.

The SYS-MMF together with the DF25 pitot tube replaces:
Extra transmitters for pressure and temperature
Extra installation of studs for pressure and temperature in the pipe
Additional condensate vessels and shut-off valves
The wiring of pressure and temperature measurement
The use of a compensation calculator or corresponding calculation modules in the PLC
Complicated programming and setups

The complete mass flow measurement is therefore via a single stud in the pipe and the parameterization is - in contrast to other multivariable transmitters - child's play.

Setup of the Multivariable SYS-MMF is simple and fast, you do not need a HART or bus connection, no expensive software, you program the transmitter yourself with a few parameters on the front screeen keypad of the device.

You can also use the SYS-MMF with classical primary elements according to ISO 5167, i.e. orifices, nozzles, venturis, etc.
