Transit Time Flow Meter

Transit Time Flow MeterThe transit time flow meter of TTFM series measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid, going upstream and downstream in to 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-calm on sensors (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 (different types of transmitters) has a DSP microprocessor, it gives signals for interfacing with the process or the control systems.The TTFM series includes a range of flow meters whose electronics is composed of a single board with high precision and fidelity.FeaturesClamp-on sensors, not necessary to stop the flow to install them (high temperature also)AC and DC supply: 85-264 VAC and 24VDC.The time difference during the measuring process could be 0.2nsAnalog(4-20mA), pulses (relays), frequence (OCT) and MOD-BUS and RS485 outputsAll the measures could be driven to the RS485 in order to save data in to a PC remotely transmitted by telemetry.
