The Transit Time Flow Meter of TTFM100/2009 NEW GENERATION series measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid, going up stream and down streamin to a pipe.
This flowmeter is mostly used to measure the flowrate 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.
Main Features The TTFM100/2009 N.G. series includes a range of flow meters whose electronics is composed of a single board: high precision, high fidelity, high competitivity.
The mainfeatures are:
Clamp-on sensors: it is not necessary to stop the flow to install them; Wettedsensors.
Thetime difference during the measuring process couldbe0.2 ns.
Analog (4-20 ma), pulses (relays), frequence (OCT) and MODBUS
All the measures could be driven to the RS485 in order to save data intoaPCremotely transmittedby telemetry.
Water treatment, slurryandprocesswater pumping;
Hydro-electric, cooling, anti-fire stations;
Water District Oilandchemical industries;
Food, paper and pharmaceutical industries;
High accuracy measuring: Linearity: better than 0.5% - Repeatability: better than 0.2%, - Accuracy: better than ± 1%.
Wide measuring range With CLAMP-ON SENSORS: Three types of clamp-on sensors for size from DN15-100, DN50-10000, DN300-6000, no pressure drop, no pipe disturbance.
Italian, French or English menu: TTFM100A/2009 NEW GENERATION can support Italian, French or English display, easy to operate, in the near future other languages will be implemented.
