Whether powders or pellets, grains or granules, the True Echo™ PRS’s dual frequencies bring the unassailably accurate level readings of radar sensors to difficult to measure solids.
The True Echo™ PRS Dual Frequency Pulse Radar Level Transmitter For Solids brings the unassailably accurate level readings of radar sensors to difficult to measure solids. Whether powders or pellets, grains or granules, the True Echo™ PRS’s dual frequencies to allow it to quickly and accurately read the complex reflections from piled solids.
The True Echo™ also automaticaly adjusts signal power for optimal accuracy and clarity. With echo masking and
damping factors programmable via software, getting dependable level readings from difficult materials is simple.
