Dwyer DTFW-2B-3W is a variable-area flowmeter designed for measuring liquids and oil. It has a temperature range of -40 to 200°F (-40 to 93°C) and offers high accuracy with liquid/oil calibration at ±2% FS and air calibration at ±5% FS. The body is made of 316 SS, brass, or aluminum, and the wetted materials include 302 SS, PTFE-coated spring and magnet, acetal or PTFE metering cone, and Buna seals. It has a pressure limit of 1500-3000 psig (100-200 bar) depending on the model. The flowmeter has a 2.5" (63.5 mm) diameter dial face and provides a repeatability of ±1% FS.
