FMC Technologies Smith Meter® positive displacement meters have long been the standard for unsurpassed reliability and superior custody transfer accuracy. Even today, Positive Displacement (PD) meters are the most accurate custody transfer meters available. Smith Meter PD meters use a rotary-vane principal to obtain direct measurements from the flow stream, without relying on inference. Smith Meter PD meters use a stream-lined flow path to minimize pressure drop across the measurement chamber. Pressure drops reduce flow through meter clearances, and reduce accuracy.
From Well Test to Truck & Rail to Marketing Terminals & Bulk Plants, Measurement Solutions is the most trusted supplier of accurate and reliable positive displacement metering equipment. Click here to see an animation on how the rotary vane technology that drives PD Meters works.
