ULTRASONIC TRANSIT TIME FLOWMETERS – TTFM100-NG SERIES

The Transit Time Flow Meter 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 used to measure the flow rate of homogeneous fluids even with a relatively high percentage of suspended solids. The measuring system is composed of two ultrasonic transducers acoustically coupled to the outside of the pipe wall or two transducers in direct contact with fluid to be measured (called wetted sensors) and a HOST unit evaluating the signals that are sent and received from the transducers. The HOST unit has a DSP microprocessor and interfaces with the process or the control systems.

The TTFM100-NG series includes a range of flow meters with single board electronics: high precision, high fidelity, high competitiveness.

Main features are:
  • Clamp-on sensors which can be used without disrupting the supply.
  • Wetted sensors for more permanent installations.
  • AC and DC supply: 110-230VAC and 12-36VDC battery supply, depending on the device. LLB-PTTFM2000-NG can be supplied by solar panel too.
  • The time difference during the measuring process could be 0.2 ns.
  • Analog (4-20 ma), pulses (relays), frequency (OCT) and RS485 MODBUS or RS232 outputs.
  • Serial communication interface RS485 MODBUS (model TTFM100-F1-NG & TTFM100-F18-NG).
  • Serial communication interface RS232 (Hand-held type TTFM100B-HH-NG).
