Series DTFF Fixed-Orifice Flowmeter for Low Flow Rates 316 SS Body, Oil/Gas/Water

Calibration

 

DWYER DTFF Fixed Orifice Flowmeter for Low Flow Rates measures water, oil, or air flow rates with great accuracy at a competitive price. DWYER DTFF Fixed Orifice Flowmeter is 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).

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.
