NUS-7 is a rugged, high performance ultrasonic level measurement transmitter, having transducer and processing electronics incorporated in one single housing. NUS-7 Saves Costs – NUS-7 is a low cost transmitter unit from KOBOLD: it has all the sophisticated echo detection features of the well accepted NUS-4 measurement systems, packaged into the 2-Wire NUS-7 sensor housing. 

If powered by DC and low power switching capability is sufficient, 2-wire transmitters are recommended. These are best applicable for multiple tank applications using HART® multi-drop systems linked to a modem plus PC. 

The 2-wire NUS-7 comes with HART® protocol as standard. Liquid Measurement – whether for liquid level measurement in sumps or tanks, for tank contents measurement, or open channel flow measurement, NUS-7 transmitters provide the answer.
