Level Measurement
Selecting Hints
Choose METRAVON radar or guided wave instruments for tank and silo level measurement. Check material, vessel geometry and signal needs, then request a model review.
Choose a level instrument around the vessel
Continuous level measurement needs a usable path from the instrument to the material surface. For a tank or silo, compare the nozzle, internals, filling stream and maintenance access before choosing a radar frequency or probe length.
| Measurement route | Installation to assess | Information needed for selection |
|---|---|---|
| Non-contact radar | The antenna looks toward the surface through a clear beam path. | Nozzle drawing, distances at high and low level, obstructions, surface shape, dust, vapour and antenna deposits. |
| Guided wave radar | A rod, cable or other specified probe extends into the vessel. | Probe clearance and removal space, material contact, buildup, moving equipment and mechanical loading. |
For example, the MV-RD701 rod or cable arrangement requires space for a contact probe. Its installation cannot be approved using the same beam-clearance check as a non-contact radar.
State whether the required result is level, volume or mass
A distance reading becomes level only after a reference is set. Volume also needs vessel geometry, and an estimate of mass needs a justified density relationship. If the purchase depends on stock quantity, state the required result and acceptance method when submitting the vessel drawing, material, process limits and control-system interface. This lets the proposed instrument and any calculation be reviewed together.
Send the material, vessel and nozzle drawing, required level span, process limits and control-system interface for an instrument recommendation and quotation.
