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

INSTALLATION REQUIREMENTS

La posición recomendada (2) es desde la pared del depósito hasta la pared exterior del tubo de instalación para cumplir los siguientes requisitos: la distancia óptima desde la pared del depósito es 1/4 o 1/6 del diámetro del depósito y la distancia mínima de instalación desde la pared del depósito es 1/10 del rango de medición. por ejemplo, para un depósito de 10 m de nivel, la distancia mínima de instalación desde la pared del depósito debe ser de 1 m.

● No se puede instalar por encima de la entrada (4).


● No puede instalarse en el centro (3), si se instala en el centro, se generarán múltiples ecos espurios y los ecos de interferencia provocarán la pérdida de la señal verdadera.


Si no se mantiene la distancia entre el instrumento y la pared del tanque, el medio en la pared del tanque se adherirá y causará ecos falsos, que deben guardarse al poner en servicio el instrumento.
