  • 10. Why Use Radar ?
    Radar transmitters fit easily into your process, They can be mounted from the top, sometimes the side or even on the outside through a glass window , plastic or GRP vessel!
    Very small blocking distances maximise your vessel capacity
    Installed or changed without emptying your tank
    Commissioned accurately on or off line without changing the level
    No moving parts means no drift or recalibration

    26
  • 27. Tank side monitoring
    The main purpose of this tank side monitering is to receive various signals from the radar , temp transmitter…..and give a standard signal to the FCU(field communication unit)
    8/12/2009
    SARAVANA KUMAR B.T
    27
  • 28. Field communication unit
    The Field Communication Unit (FCU) is a data concentrator that continuously polls data from field devices such as Radar Tank Gauges, Data Acquisition Units and Remote Display Units and stores them in a buffer memory. Whenever a request for data is received, the FCU can immediately send data from a group of tanks from the updated buffer memory . The FCU acts as a slave on the group bus and as a master on the field bus. The unit has six communication ports. The ports can be individually configured as either group bus ports or as field bus ports according to one of the alternatives below:
    8/12/2009
    SARAVANA KUMAR B.T
    28
  • 29. Field communication unit
    An interface board can be connected for each communication port. These boards can be either FCM boards for the TRL/2 Bus or FCI boards forRS-485 communication. Two group bus ports canal so be configured as RS-232 by connecting a jumper connector instead of an FCM or FCI board . As standard the Field Communication Unit is delivered with six FCM boards and two RS-232jumper connectors.

    30
  • 31. Field bus modem
    BENEFITS
    • Increases the possible distance between a FCU and TankMaster PC
    • Diagnostic LEDs on front cover
    • Enables multidrop - one TankMaster can serve many FCUs via the FBM 2180
    • Multiple mounting options
    • Enables FCU redundancy

    31
  • 32. OVERFILL PROTECTION
    The measurement of the level for overfill protection is independent of other gauging systems installed on the tank.
    High and high-high level alarms that can bee seen or heard by the operator controlling the tank transfer, such as audible sirens or horns and visual lights.
    A device that when activated can automatically trigger a shut down procedure for the process causing the alarm.
    8/12/2009
    SARAVANA KUMAR B.T
    32
  • 33. ore stringent regulations may be required for facilities with:
    Permeable ground materials that are inside the containment area
    "Old" tanks that can be more susceptible to corrosion.
    Tanks near surface water such as rivers, wetlands or lakes
    8/12/2009
    SARAVANA KUMAR B.T
    33
  • 34. Measuring for Overfill 
    Single point measurement 
    For single point measurement, an instrument is installed at the high and/or high-high level and will sense when the product reaches that level. The most common of which are simple stand alone mechanical switches or electronic tuning fork technology. Single point measurement devices tend to be simple, very reliable, low cost units that can be installed easily
    8/12/2009
    SARAVANA KUMAR B.T
    34
  • 35. continuous measurement
    For continuous measurement, a standard level gauge is a common solution. Any of the major gauging technologies can be used, float and tape (mechanical), servo, radar or magnetostrictive technologies. Each provides their own benefits based on the application. Continuous measurement is favored by some over single point measurement. Your operators can check the status of the gauge at any time and the gauge's operation can be monitored for deviation against the primary level device. The main benefit - you know if there is a problem with the gauge before it becomes an overfill problem and your operators do not need to climb a tank to check the operation.
