The Sultan 234 can be powered using loop power (2-wire), 3-, or 4-wire sources. It does not matter which power source is used; the Sultan Acoustic wave can measure in difficult environments. These powerful instruments emit an acoustic wave pulse that is then reflected from the surface of the material being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false or spurious echoes. The measured signal is temperature compensated to provide maximum accuracy to the outputs and display. There is no direct contact with the media, which can extend up to 393 feet from the sensor.
