The 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 the 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.
Insertion DualPulse Flowmeter features
- IP68 (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 is suitable for “hot tap” installation.
- BI-Directional Flow Measurement
