INTRODUCTION
Thanks for buying an Ultrasonic Transit Time Flowmeter TTFM100-NG series.
The device measures flowrate by calculating the spreading time of an ultrasonic wave in a
liquid, going upstream and downstream into a pipe. This flowmeter is mostly used to
measured the flowrate of homogeneous fluids , with a very little percentage of suspended
solids and possibly without gas bubbles.
Its peculiar installation makes this devices suitable for measuring aggressive fluids (acids,
basic and dissolvents) or very soiling fluids(oil and fuels).
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) and a HOST unit elaborating the sent and received signals from
the transducers. The HOST unit has a DSP microprocessor, it gives signals to interfacing
with the process or the control systems.
The devices main features are:
•
Clamp-on sensors: it is not necessary to stop the flow to install them.
•
AC and DC supply: 230 VAC.
•
The time difference during the measuring process could be 0.2 ns.
•
RS232 output.
•
All the measures could be driven to the RS232 in order to save data into a PC or a
serial printer.
