The Dwyer Instruments TE-P-1 is a high-performance orifice plate flowmeter from the Series TE, engineered for precise flow measurement in industrial processes. Constructed from one-piece PTFE, this flowmeter offers exceptional chemical resistance, weather resistance, and flame retardancy (without factory gaskets), ensuring durability in demanding environments. The TE-P-1 is designed for line sizes from 1/2″ to 24″, providing versatility across a wide range of applications.
Key Features & Highlights
- One-piece PTFE construction for superior chemical resistance and low friction (minimum wear)
- Integral gaskets and metering taps in a unique holder/carrier ring
- Easy installation between standard flanges – no orifice flanges required
- Orifice plate thickness of 1/4″ for greater stability
- Weather resistant and flame retardant (without factory gaskets)
- Cost-effective alternative to conventional orifice plates and other primary differential producers
Applications
The Series TE orifice plate flowmeter is suitable for use with gases, liquids, corrosive fluids, and high-temperature fluids. It is ideal for applications in chemical processing, water treatment, HVAC, and industrial manufacturing where accurate flow measurement and resistance to harsh media are critical.
