The intended application for the MG transmitter and Level- Mate Monitor is in tanks with line power from a local source but no communication lines to the control room.
MTS Sensors uses its Level Plus Model MG liquid-level transmitter to measure the level in storage tanks. The tank-level reading goes via Modbus to the OleumTech LevelMate Monitor. The Monitor uses the licensefree 902-928-MHz ISM band with FHSS (frequency-hopping spread spectrum) and FSK (frequency-shifting key) modulation technology. It beams sensor data back to a control room where an OleumTech DataHub resides. The output from the DataHub goes to a fieldbus controller that sends the information to the Internet. Viewers can open the Web site and poll the unit to find the last measurement.
