The Kobold ultrasonic level meter, model NUS-4, is used for non-contact, continuous level and volume measurement in vessels or for flow measurement in open channels. Level measurement technology based on the non-contacting ultrasonic principle is especially suited for applications where, for any reason, no physical contact can be established to the surface of the material to be measured.

Such reasons may include corrosive attack by the process medium against the measuring devicematerial (acids), possible contamination (sewage) or particles of the process medium adhering to the measuring device (adhesive materials).The ultrasonic level metering technology is based on the principle of measuring the time required for the ultrasound pulses to make a round trip from the sensor to the level to be measured and back.
