Overview The NUFLO 1502 WECO union liquid turbine flowmeter incorporates a tungsten carbide shaft and bearings to withstand the rugged conditions of the oilfield environment. Over the years, this flow meter has earned an unsurpassed reputation for withstanding severe punishment while maintaining operational and measurement integrity. Specifically, these meters indicate flow rate and measure total throughput of a liquid line. As liquid flows through the meter and over the rotor, the rotor turns at a speed that is directly proportional to the flow rate. A magnetic pickup senses the rotor blades as they pass and generates an electrical (sine wave) signal. Then, these electrical pulses are transmitted to the flow measurement readout equipment. Optional rotor configurations and/or finishes allow erosive or corrosive fluids such as mud or cement slurries and hydrochloric acid to be pumped routinely.
