The ELM-R26 series intelligent radar level gauge emits and receives extremely short microwave pulses with very low energy through an antenna system. Radar waves travel at the speed of light. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in a very short period of time. Even in complex working conditions where false echoes exist, microprocessing techniques and debugging software can accurately analyze the echoes of the material level.

The antenna receives reflected microwave pulses and transmits them to the electronic circuit. The microprocessor processes this signal and identifies the echoes generated by the micro pulses on the surface of the material. The correct identification of echo signals is completed by pulse software, with an accuracy of up to millimeter level.

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

By inputting the empty tank height E (=zero), full tank height F (=full range), and some application parameters to set, the application parameters will automatically adapt the instrument to the measurement environment. Corresponding to 4-20mA output.

Application areas:

Mainly used for measuring the material level height of solid storage tanks in industries such as cement, steel, electricity, coal, and building materials (such as powder, block, and granular materials).

Product features:

1.Suitable for precision measurement of large and long-distance dust

2.Universal flange, small beam angle, high sensitivity

3. Water droplet antenna or conical antenna are optional.
