The Magnetic Level Gauge Type MAG-RDR (Remote Direct Reading) can be installed on any boiler, as a completion of the Glass Level Gauges (which are compulsory) and of the Magnetic Level Gauges.

Two connections on boiler drum are sufficient for installation.

The plant consists of:

• 1-Connections on boiler drum
• 2-Condensate container at constant level fitted on top connection, with a vent valve or a plug
• 3-Downwards pipes
• 4-Manifold cock for shut-off and reset
• 5-Mud traps
• 6-Differential pressure gauge containing a special fluid heavier than water, not water-soluble. One of the two branches of the pressure gauge is fitted with a float containing a magnet moving upwards and downwards depending on water level of drum.
• 7-Indicating scale for direct level reading outside of differential pressure gauge.

The system can also be extended (See page 14 and following) in details with the installation of:

• 8-Sensing element positioned externally at float level
• 9-Signal transmitter current loop type 2 wires, 4÷20 mA (Hart protocol communication available) connecting the sensing element with the control instruments and/or with the indicator/transmitter device MST-X;
• 10-Indicator/transmitter device MST-X usually installed in the control room equipped with:
  • Output power supply for MST sensing element;
  • Led indicator column (23 red/green bicolour leds);
  • Analogic display indicator with settable configuration (measuring units, zero scale, format, percentage);
  • No. 4 thresholds indicated by leds;
  • Failure signal via yellow blinking led;
  • Output connecting port for PC, industrial PLC for process control and/or data storage;
  • Permanent memory cash for programmable data.

These instruments are patented in Italy as well as in other Countries.
