Differential pressure orifice flow-meter
DTFF series DWYER

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 3000 psig (206.7 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.
