Solutions

RKL-02 Radar Liquid Level Transmitter antenna emitter narrow microwave pulse, the pulse in the space at the speed of light transmission, met on the surface of measured medium, some of its energy is reflected back, by the same antenna.Firing pulse and receives the pulse interval and the antenna to the surface of the measured medium is proportional to the distance, to calculate the distance on the surface of the antenna to the measured medium.

FEATURES

  * Small beam Angle, the energy concentration, strong anti-interference,high accuracy and reliability
  * Range of up to 70 meters, covering large reservoir and other water level measurement
  * Good stability
  * Multiple output signal is optional
  * Transmitted power is extremely low, no harm to human body and environment
  * Easy Installation

APPLICATIONS

  * River water level measurement
  * Lake water level measurement
  * Shallow water level measurement
  * Hydrographic survey
  * Environmental protection

MOUNTING

Radar antenna launch microwave has a certain Angle, from the edge of the antenna to the surface between the measured medium, and launch a microwave beam radiation areas shall not be an obstacle.

In order to ensure that products meet the requirements of IP67 rating,please make sure:
  The sealing head intact;
  The cable is not damaged;
  Ensure that the cable used in line with the requirements of electrical connection in the specification;
  Before entering the electrical interface, the cable bending down, to ensure that water will not flow into the shell, as shown in;
  Please tighten the cable seal head, see;
  Please return the unused electrical interfaces to blind plugging plugging tight, see.
