TECHNICAL SPECIFICATIONS NUFLO Liquid Turbine Flow Meters Accurate Flow Measurement In 1957, this flow meter was developed with a tungsten-carbide shaft and bearing to withstand the rugged conditions of the oil field. Over the years, it has earned an unsurpassed reputation for withstanding severe punishment while maintaining operational and measurement integrity. Today, it remains a strong seller among Cameron’s NUFLO™ liquid measurement products. Benefits Accurate and repeatable measurement An economical solution for turbine flow meter applications of a liquid line. As liquid flows through the meter and over the rotor, Easy installation and a variety of end connections the rotor turns at a speed that is directly proportional to the flow rate. A Minimum maintenance required NUFLO turbine flow meters indicate flow rate and measure total throughput magnetic pickup senses the rotor blades as they pass and generates an electrical (sine wave) signal. These electrical pulses are then transmitted to the flow measurement readout equipment.

Applications Accuracy Cameron offers turbine flow meters in a variety of end connections and accuracy levels. Typical applications are: Cameron offers two meter grades to satisfy various linearity requirements.
