Guided wave radar level transmitter

Continuous level measurement in liquids and solids with guided wave radar sensors.

Level measurement using guided wave radar technology,

is based on the reflection of microwaves on surface media.

What is guided wave radar level transmitter?

Guided wave radar devices, also called wave guided radar level transmitter,

have no moving parts and require minimum maintenance.

They can measure both level and the interface between two media.

The guided wave radar level gauge is applied to water storage tanks,

acid and alkali storage tanks, slurry storage tanks,

solid particles, and small oil storage tanks.

All kinds of conductive, non-conductive media, corrosive media.

Such as coal bunkers, ash silos, oil tanks, acid tanks, etc.

We also supply level transmitters, like:Pressure Level Transmitter;Submersible Level Transmitter; and (DP) level transmitter

What is guided wave radar?

Micropower impulse radar (MIR) combines time domain reflectometry (TDR),

equivalent time sampling (ETS),

and modern low power circuitry.

This synthesis of technologies creates a high-speed Guided Wave Radar (GWR) transmitter.

The electromagnetic pulses are propagated via a waveguide,

that focuses the energy and yields a system,

many times more efficient than Non-Contact Radar (Non-contact radar level transmitters).

Time domain reflectometry (TDR)

TDR uses pulses of electromagnetic (EM) energy to measure distances or levels.
When a pulse reaches a dielectric discontinuity (such as one created by a media surface),
a portion of the pulse is reflected.
The greater the dielectric difference between air and the process medium being measured,
the greater the amplitude of the reflection.

Equivalent time sampling (ETS)

ETS, or Equivalent Time Sampling, is used to measure the high speed, low power EM energy.
ETS is a critical key in the application of TDR to vessel level measurement technology.
The high-speed EM energy (1000 ft/us) is difficult to measure over short distances,
and at the resolution required in the process industry.
ETS captures the EM signals in real time (nanoseconds),
and reconstructs them in equivalent time (milliseconds),
which is much easier to measure with today’s technology.

Guided-wave radar (GWR) level transmitter working principle

Levelflex works with high-frequency radar pulses,

which are emitted and guided along with the probe.

As the pulse meets the medium surface,

part of the emitted pulse is reflected due to a change of the dc value (relative dielectric constant).

The Time-of-Flight between pulse launching and receiving is measured,

and analyzed by the instrument and constitutes a direct measure for the distance,

between the process connection and the product surface.
