Magnetic flow measurement device offers Profibus interface

Siemens process instruments has released a new version of the SITRANS FM magnetic flow meter that now provides the additional capability of digital communications using Profibus PA.

The unit's new features include internal simulation for all output functions, as well as complete flow simulation, which reduces set up and maintenance. Troubleshooting is made far easier thanks to automatic self-monitoring of the converter and the connected flow sensor.

Installation and set up is quick and easy, through automatic recognition of the sensor type and calibration data as result of the SmartPlug(tm) memory chip. When used with SIMATIC(tm) PDM software, the SITRANS FM flow meter can be integrated directly into a complete Profibus system, so flow data is available at the control system.

The SITRANS FM is a microprocessor-based transmitter with a built-in alphanumeric display, and is available for mounting both integrally and remotely from its flow sensor. The flow meter can be used for medium flow velocities up to 12m/s and for a minimum conductivity of 3 µS/cm. The SITRANS FM provides analogue output with HART protocol, and digital outputs for pulses, device status, limits, flow direction, frequency output.
