26G radar level gauge
The DRD10 series sensor is a 26G high frequency radar level measuring instrument with a measuring distance of up to 80 meters. Antennas are further optimized, and new fast microprocessors allow for higher rate signal analysis processing, allowing the meter to be used for measuring conditions in complex environments: reactors or solid silos.
The DRD10 radar object level antenna emits a narrow microwave pulse, which is transmitted downward through the antenna. After the microwave touches the surface of the measured medium, it is reflected back, received by the antenna system again and transmitted to the electronic circuit, which is automatically converted into the object level signal (because the microwave propagation speed is extremely fast, The time it takes for electromagnetic waves to reach the target and bounce back to the receiver is almost instantaneous)
Features:
※ Non-contact radar, no wear, no pollution
※ Small antenna size, easy to install
※ Shorter wavelength, better reflection on tilted solid surfaces
※ The measurement blind area is smaller, and good results can be obtained for small tank measurement
※ Small beam Angle, energy concentration, enhance the echo ability at the same time, but also help to avoid dry scratches
※ Almost unaffected by corrosion and foam ※ Almost unaffected by water vapor in the atmosphere, temperature and pressure changes ※ Serious dust environment will not affect electromagnetic wave operation
* High signal-to-noise ratio for better performance even under fluctuating conditions * High frequency is the best choice for measuring solid and low dielectric constant media
※ Optional 4-20MA(DC two-wire AC four-wire system) or RS-485 communication, strong resistance to dry scratching

Installation precautions
1.
Datum level
2.
The minimum distance between the center or symmetry axis of the container and the tank wall is 200mm
Conical can
The top plane, which can be installed in the middle of the tank top, can ensure the measurement to the conical bottom
A storage tank with a stock pile
The antenna should be vertically aligned with the material surface. If the material surface is uneven and the pile Angle is large, the universal flange must be used to adjust the horn Angle so that the horn is aligned with the material surface as much as possible
Error demonstration
Conical can
Cannot be installed above the inlet
1.
Correct
2.
Wrong
The instrument can not be installed in the middle of the arch or round tank roof, in addition to producing indirect echoes, but also affected by multiple echoes. Multiple echoes may be larger than the threshold of true echoes, because the top can concentrate multiple echoes, so it cannot be installed in a central location.

Correct
2.
Wrong
When there are obstacles in the tank affecting the measurement, it is necessary to install a reflection plate to measure normally.
