Insertion Dual Pulse
Turbine Flow Meter


TDP490 & DP525 are cost effective stainless steel flowmeters for measuring the ow of water, fuels & other low viscosity liquids in pipes sizes 1.5”~100” (40~2500mm).

Insertion flowmeters are installed with the metering head 1/8th into the pipe resulting in very little pressure drop. They do not require external power when used with the Trimec rate totalisers however some options such as high temperature & non-magnetic models require external power.

Applications include HVAC, hot & chilled water, fire systems, water distribution (management & treatment), boiler feed water & hydrant flow testing.


  • P68 (NEMA6) submersible 316SS construction
  • Low cost of ownership, wide flow range
  • Rugged & compact design
  • Intrinsically safe hazardous area versions
  • Integral or remote pre-amplifiers & flow instruments
  • DP525 version suitable for “hot tap” installation
  • BI-Directional Flow Measurement
