Series DTFF Fixed-Orifice Flowmeter
Brand: Dwyer Instruments, LLCThe Series DTFF Fixed-Orifice Flowmeter for Low Flow Rates measures water, oil, or air flow rates with great accuracy at a competitive price.
Rugged stainless steel construction ensures great compatibility and is an excellent choice for high line pressure applications, with a maximum pressure of 3,000 psig (200 bar).
This is all without sacrificing the sensitivity required for low flow measurements. Available in a wide range of flow rates for each calibration, with stainless steel construction as standard. Comes pre calibrated for horizontal in-line mounting.
Features- Rugged Stainless Steel construction ensures great compatibility and is an excellent choice for high line pressure applications, with a maximum pressure of 3000 psig (200 bar)
- High Sensitivity for low flow measurement
- Shatter proof construction, unlike glass tube variable area flowmeters, yields long operation life
