Direct Reading Frequency Meter (DRF)
It is constructed from cylindrical cavity resonator with a variable short circuit termination. The shorting plunger is used to change the resonance frequency of the cavity by changing the cavity length. DRF measures the frequency directly. It is particularly useful when measuring frequency differences of small changes.

Frequency Meter (Micrometer type)
These frequency meters are intended for moderate accuracy application in microwave measurement and are usually best for this purpose. These permit full power flow down the transmission line except at the turned frequency. It consists of a cavity, plunger and the section of standard waveguide. The plunger ensures precise control of its position enabling frequency measurement with high accuracy.
