Molded of tough polycarbonate plastic. Used to Indicate & Manually control Air or Gas flow from 16-160 cc/min. The compact flow meters are ideal for MTI tube furnaces. Easy to read design - The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background. Construction assures accuracy - All flow meter bodies are injection molded of tough, clear, shatter-proof polycarbonate plastic around a precision tapered pin. Critical internal diameter of the variable orifice tube is held within .0004". The result is accurate and repeatable readings. The backbone into which pipe thread inserts are welded to absorb piping torque. Precision metering valves of stainless steel valves permits precise flow adjustments.  Accuracy is within 2.5% of full scale reading
