Differential pressure transmitter SYS-MMF

4-20 mAHARTModbus

The SYS-MMF is a low-cost, multivariable transmitter for simple 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-MTF type has only a differential pressure sensor and a temperature input (no pabs sensor), so it can be used e.g. for saturated steam, or if the pressure in the application can be assumed to be constant. 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 water. In combination with the deltaflow, the SYS-MMF is a particularly effective time and money saver. Install a completely p and T-compensated mass measurement via a single stud in the pipe. In the left picture you can see, for example, a complete presure an temperature compensated steam mass measurement. The SYS-MMF together with the deltaflow 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
