Non Contact Ultrasonic Level Transmitter
Non Contact Ultrasonic Level Transmitter consist of a family of Ultrasonic with a frequency range in KHz. The offered Ultrasonics are available in different configuration and process connections as per customer requirement. Ultrasonic Level Transmitters provide a cost effective and reliable solution for level measurement for non aggressive liquids and slurry applications
Principle
The Transit Time Flow Meter of TTFM100 NEW GENERATION (NG) series measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid, going upstream and downstream into a pipe. This flow meter is mostly used to measure the flow rate of homogeneous fluids, also with a quite high percentage of suspended solids.
The measuring system is composed of a couple of ultrasonic transducers acoustically coupled to the external pipe’s wall (it is also possible to use transducers in direct contact with fluid to be measured – called wetted sensors) and a HOST unit elaborating the signal that are sent and received from the transducers.
The HOST unit has a DSP microprocessor, it gives signals for interfacing with the process or the control systems.
