NUS-7 - Ultrasonic Level Transmitter for Liquids

Brand: KOBOLD Instruments, Inc

The NUS-7 is a rugged, intelligent, high performance ultrasonic level transmitter, with both transducer and processing electronics incorporated into a single housing. 

The economical, plastic NUS-7 has all the sophisticated echo detection features of our proven NUS-4 measurement systems, packaged into the 2-wire, NUS-7 sensor housing. 

2-wire transmitters are recommended for applications powered by DC and for low switching capability. 

They excel in multiple tank applications using HART® multi-drop systems linked to a modem plus PC. 

The NUS-7 comes standard with HART® protocol. NUS-7 transmitters can provide the answer for level measurement in sumps and tanks or open channel flow measurement. 

It is suited for most liquids under various process conditions. 

It comes with a scalable, 4-20 mA output and a programmable relay.
