DP490 & DP525 Insertion DualPulse Flowmeter by Trimec

DP490 Insertion Dual Pulse Flow meter by Trimec IndustriesThe Trimec DP490 Insertion DualPulse Flow Meter insertion flow transducer is an innovative design that combines well proven technology with modern engineering materials to provide a cost effective and simple means of measuring the flow of water and a wide variety of low viscosity liquids.

  • All stainless steel construction
  • Suits pipes 40~2500mm (1.5~100″)
  • Low installed cost
  • Simple to install
  • Unique head design to extend linear measuring range
  • Two independent pulse outputs with high noise immunity (CE compliant)
  • High pressure submersible design
  • Hot tap option 

Trimec Industries DP490 & DP525 are cost effective stainless steel flowmeters for measuring the flow of water, fuels & other low viscosity liquids in pipes sizes 1.5″~100″ (40~2500mm). The 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 Trimecrate totalisers however some options such as high temperature & non-magnetic models require external power.
