GENERAL DESCRIPTION:

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.
  • ACandDCsupply: 85..264VACand24VDC.
  • Thetime difference during the measuring process couldbe0.2 ns.
  • Analog (4-20 ma), pulses (relays), frequence (OCT) and MODBUS
  • RS485outputs.
  • All the measures could be driven to the RS485 in order to save data intoaPCremotely transmittedby telemetry.


TypicalUse:

  • Water treatment, slurryandprocesswater pumping;
  • Flowbalancing;
  • Hydro-electric, cooling, anti-fire stations;
  • Water District Oilandchemical industries;
  • Extraction industries;
  • Food, paper and pharmaceutical industries;
  • Car industries;
