Magnetic Inductive Flow Meter EPS
Function: 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.
Range: depends on flow channel / weir
Accuracy: depends on flow channel / weir
Output: 4 - 20 mA, relay, LCD-indication and programming unit

Applications

The sensor emits an ultrasonic pulse train and receives the echoes reflected. The electronic evaluates the echo time of the pulses and determines the level. The evaluating electronics is mounted compact on the unit. For remote transmission, a norm signal output and for monitoring purposes, a relay contact is available. For programming and for local display, the units may be delivered with an optional pluggable programming unit with LCD display.

The sensors have a  total beam angle of 5°-7° at -3 dB. This ensures a reliable measurement in narrow silos with uneven side walls as well as in process tanks with various protruding objects. Furthermore, as a result of the narrow beam angle - the emitted ultrasonic signals have an outstanding focusing - deep penetration through gases, vapour and foam is ensured.
