NYRD703 1.8GHz Guided Wave Radar Level Meter Level Transmitter Measurement Of Low Dielectric Constant Media

NYRD703 1.8GHz Guided Wave Radar Level Meter 

 

The guided wave radar level meter is a level meter based on the principle of time domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. Part of the pulse of the level meter is reflected to form an echo and return to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse during that period, and the liquid level height is calculated.

Radar Level Meter Operating Principle

 

Guided Wave Radar is the kind of measuring instrument that is based on the principle of time travel. The radar wave travels at the speed of light, and its running time can be converted into a level signal by the electronic components. The probe emits high-frequency pulses which spread along the cable, and the pulses are reflected back when they encounter the material surface and received by the receiver inside the meter. The distance signal is then converted to the level signal.

Radar Level Meter Installation requirements

 

Measurement Range

 

The blind area refers to the minimum distance between the highest level of the material surface and the measurement reference point.

The bottom blind area refers to the distance near the cable bottom that cannot be precisely measured.

The effective distance is the one between the top blind area and the bottom blind area.

 

Note: Only when the material level is at between the top and bottom blind areas can a reliable measurement of the material level be guaranteed.

 

Installation Guide

 

The following installation guide is suitable for that of cable and rod probes for measurement of solid particles and liquid. The coaxial tubular probe is applied only to the liquid object.

Installation position:

Try to stay away from the outlet and inlet.

The meter should not touch the tank internal wall for metal tanks and plastic tanks. If it is a metal tank, the material level meter should not be installed at the center of the tank.

It is proposed to install at 1/4 of the silo diameter.

Probes of cable or rod types should keep a distance away from the tank wall not less than 30cm.

The probe bottom should be about 30mm to the tank bottom.

The probe should keep a distance not less than 200mm from the obstacles within the tank.

The sensor can be installed at the center of the tank top, if the bottom of the container is a cone, so the measurement can be taken to the tank bottom.

 

The picture on the right shows the rod-type radar installation diagram, mainly used for liquid level measurement.

 

The down-pulling force applied to the cable

 

When charging and discharging, the material will generate down-pulling force to the cable, which is determined by the following factors:

  • cable length
  • material density
  • tank diameter
  • cable diameter

Installation guide for liquid measurement

 

The installation guide below applies to rod- and cable-type probes. The tubular probe measurement is not related with the installation method.

 

Installation position

  • Distance to the tank wall is suggested as the 1/6 ~ 1/4 of tank diameter (300mm at least, 400mm at least for concrete tank)
  • Do not install at the metal tank center
  • Do not install at the outlet
  • Remember the probe bottom should keep a distance greater than 30mm when select the probe length.
  • Pay attention to the medium temperature.

Obstacles within tank

  • Probe should keep a distance not less than 200mm away from the obstacles.

Interference removal

  • Interference suppression: The software could suppress the interference echo, so as to achieve the ideal effect of measurement.
  • Bypass, wave guide pipes or tubes could be used to suppress the interference when the viscosity is not greater than 500cst.
