PRODUCT OVERVIEW

The KD90X series sensor is a 26G radar water level meter measuring instrument with a measuring distance of up to 80 meters. The antenna is further optimized for processing, and the new fast microprocessor allows for higher speed signal analysis and processing, making the meter available for measurement of a variety of highly corrosive liquids.

THE PRODUCT PRINCIPLE

Radar water level meter antenna transmits a very narrow microwave pulse, this pulse propagates in space at the speed of light, encountering the surface of the measured medium, part of its energy is reflected back and received by the same antenna. The time interval between the transmitting pulse and the receiving pulse is proportional to the distance from the antenna to the surface of the measured medium. Due to the extremely high propagation speed of electromagnetic waves, the time interval between the transmitted and received pulses is very small (nanosecond order) and difficult to confirm. 90X series 26G radar water level meter uses a special demodulation technology to accurately identify the time interval between the transmitted and received pulses, so as to further calculate the distance from the antenna to the surface of the measured medium.

                                                                                                                                            A: range setting, B: low level adjustment, C: high level adjustment, D: blind range

The reference surface for measurement is: the bottom surface of the thread or the sealing surface of the flange.

Note: When using the radar water level meter, be sure that the highest level cannot enter the measurement blind zone (the area shown in D in the figure).

  PRODUCT FEATURES

The industry-recommended radar water level meter adopts

 a transmitting frequency of 26GHz, thus having:

● Small beam angle, concentrated energy, stronger

 anti-interference capability, and greatly

 improved measurement accuracy and reliability.

● Small antenna size, easy to install and add

 dust cover and other antenna protection devices.

● Lighter weight of about 1KG, easy to install.

● Measuring range up to 70 meters, covering

 water level measurement in large reservoirs, etc.

● Multiple output circuit interfaces to work with

 the acquisition system.

The radar water level meter adopts pulse operation mode, and the emission power

 is extremely low, which is harmless to human body and the environment.

INSTALLATION REQUIREMENTS

Please note the following to ensure that the instrument can be installed correctly: Please allow enough space for installation. Please avoid installation where there is strong vibration.

Note: When the radar antenna transmits microwave pulses, there are certain launch angle. From the lower edge of the antenna to the surface of the measured medium, and the area radiated by the emitted microwave beam must not have obstacles. Therefore, the installation should be as far as possible to avoid obstruction facilities, if necessary, "false echo learning". When installing the instrument, we should also pay attention to the following: the highest level should not enter the measurement blind zone; the instrument must be connected to the earth and increase the lightning protection measures; outdoor shading and rain protection measures should be taken.
