Radar Level Meter Adopted 26G High Frequency Radar Sensor

Radar Level Meter Adopted 26G High Frequency Radar Sensor

Description

This series of radar level meter adopted 26G high frequency radar sensor, the maximum measurement range can reach up to 70 meters. Antenna is optimized further processing,
the new fast microprocessors have higher speed and efficiency can be done signal analysis, the instrumentation can be used for reactor, solid silo and very complex measurement environment.

Principle

Radar level transmitter antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals (because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous).

Datum measurement: Screw thread bottom or the sealing surface of the flange.
Note: Make sure the radar level meter the highest level cannot enter the measuring blind
area (Figure D shown below).

Features

Ø Small antenna size, easy to install; Non-contact radar, no wear, no pollution.

Ø Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.

Ø Serious dust environment on the high level meter work has little effect.

Ø A shorter wavelength, the reflection of solid surface inclination is better.

Ø Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.

Ø The measuring range is smaller, for a measurement will yield good results.

Ø High signal-to-noise ratio, the level fluctuation state can obtain better performance.

Ø High frequency, measurement of solid and low dielectric constant of the best choice.

The Installation Requirements

Installation guide:

Be installed in the diameter of the 1/4 or 1/6. Note: the distance between the tank wall minimum distance should be tank high 1/10.

Note: 1. datum

2.The container center or axis of symmetry

The top conical tank level, can be installed at

the top of the tank is intermediate, can guarantee the measurement to the conical bottom.

A feed antenna to the vertical alignment surface. If the surface is rough, stack angle must be used to adjust the angle of cardan flange of the antenna to the alignment surface.

(Due to the solid surface tilt will cause the echo attenuation, even Loss of signal.)

Typical installation errors:

Ø Conical tank cannot be installed above the feed port.

Note: outdoor installation should adopt sunshade.

1. Correct

2. Error rainproof measures

Ø The instrument cannot be installed in the arched or domed roof intermediate. In addition to produce indirect echo is also affected by the echoes. Multiple echo can be larger than the real value of signal echo, because through the top can concentrate multiple echo. So cannot be installed in a central location.

1. Correct

2. Error

Ø There are obstacles affecting measurement needed reflection plate.

1. Correct

2. Error

The Electrical Connection

The power supply voltage:

(4~20)mA/HART (Two wire system)

The power supply and the output current signal
sharing a two core shield cable. The supply voltage range see technical data. For intrinsically safe type must be a safety barrier between the power supply and the instrument.

(4~20)mA/HART(Four wire system)

Separate power supply and the current signal,
respectively using a power cable. The supply voltage range see technical data.

RS485 / Modbus

Power supply and Modbus signal line separate drespectively using a shielded cable, the power supply voltage range see technical data.
