The Radar Level Transmitters are excellent devices for non contact level measurement. The microwave impulses, emitted by the radar’s antenna, travel at speed of light and a part of their energy, reflected by the surface of the medium to be measured, is received by the same antenna. The period of time (flying time) between the emission and the arrival of the impulses, is proportional to the existing distance between the antenna and the surface of the medium to be measured.
The electromagnetic wave travels at a very high speed (nanosecond), so it is difficult to identify it: Our Radar Level Transmitters however, through it’s integrated management system, use a suitable demodulation technology that allows them to identify the period of time between the emission of the impulses and their corrected reception and, consequently, determine and measure the level.
The Alphanumeric Display allows the user not just to enter the data for the level measurement, but even to display and isolate false echoes .
EIP_WARE is a software for the configuration and calibration of the units with a PC is available too, it has HART communication protocol and it is used with a standard HART MODEM.
An advanced microprocessor and the “EchoDiscovery” technology make the device suitable for measurements in critical areas with hard conditions, such as high temperatures and high pressure. The function “False Echo Storage” identifies the correct echo, even if there is a false echo: in this way a correct measurement is gained. An integrated temperature sensor compensates the temperature in realtime.
The Radar Level Transmitters can be installed both in metallic or non metallic tanks\ their use is not harmful to humans or environment.
