PRODUCT OVERVIEW

6GHz intelligent series radar level meter is suitable for non-contact continuous measurement of level of liquid, slurry, granule and lump material, suitable for temperature and pressure changes; occasions where inert gas and volatilization exist.


It adopts the measurement method of microwave pulse, and can work normally in the industrial frequency band range. Low beam energy, can be installed in a variety of metal, non-metallic containers or pipes, no harm to human body and the environment.

THE PRODUCT PRINCIPLE

Very short microwave pulses of very low energy are transmitted and received through an antenna system. The radar wave travels at the speed of light. The running time can be converted into a level signal by means of electronic components. A special time-stretching method ensures stable and accurate measurements in a very short time. Even in the case of complex conditions and spurious echoes, the level echoes can be accurately analyzed using microprocessor technology and commissioning software.

The antenna receives the reflected microwave pulses and transmits them to the electronics. The microprocessor processes this signal and identifies the echoes generated by the micropulses on the material surface. The correct identification of the echo signal is done by the pulse software with an accuracy of millimeters.


The distance D from the material surface is proportional to the time travel T of the pulse: D=C×T/2; where C is the speed of light. Since the distance E from the empty tank is known, the level L is: L = E - D.


It is set by entering the empty tank height E (=zero), full tank height F (=full range) and some application parameters, which will automatically adapt the instrument to the measurement environment. Corresponds to 4-20mA output.


PROTECTION GRADE

This instrument fully meets the requirements of protection class IP66/67. 

Please make sure that the cable sealing head is waterproof. As shown

How to ensure that the installation meets the requirements of IP67:

Please make sure that the sealing head is not damaged.

Please ensure that the cable is not damaged.

Please ensure that the cable used meets the requirements of the electrical connection specification.

Before entering the electrical connection, bend the cable downwards to ensure that

 water does not flow into the housing, see ①

Please tighten the cable sealing head, see ②

Please plug the unused electrical connections with blind plugs, see ③

TECHNICAL PARAMETERS

INSTALLATION REQUIREMENTS

Recommended location (2), the tank wall to the outer wall of the installation short pipe should meet the following requirements: the best distance from the tank wall is 1/4 or 1/6 of the tank diameter, the minimum installation distance from the tank wall is 1/10 of the measurement range. for example: 10m level tank, the minimum installation distance from the tank wall should be 1m.

● Cannot be installed above the inlet (4)


● It cannot be installed in the center (3). If it is installed in the center, multiple false echoes will be generated and the interference echoes will cause the real signal to be lost.


● If the distance between the instrument and the tank wall cannot be maintained, the medium on the tank wall will adhere to cause false echoes, and false echoes should be stored during the commissioning of the instrument.

                                                                                                                                                                Installation of conical tank

The top plane of the conical tank can be installed in the middle of the top of the tank to ensure the measurement to the bottom of the cone.

                                                                                                                                                                  Storage tanks with stockpiles

When there is a stockpile, the antenna should be vertically aligned with the material surface. If the material surface is not flat and the pile angle is large, a universal flange must be used to adjust the angle of the horn so that the horn is aligned with the material surface as much as possible. (Because the inclined solid surface will cause echo attenuation and even loss of signal)

                                                                                                                                                                   Installation instructions in the tank

In the signal beam, the following installations should be avoided:such as (1): limit switch, temperature sensor, etc.Symmetrical devices such as (2): vacuum ring, heating coil, baffle, etc.

If there are (1) (2) interfering objects in the tank, the still-pipe should be used for measurement.
