True industry standards, the BARTON Floco and Flotrac liquid positive displacement (PD) meters are staples in harsh environments that demand consistent, repeatable, and rugged performance. 

BARTON Floco Series F Liquid PD Meter

The Floco Series F liquid PD meter has a unique rotor design that provides sustained accuracy even under adverse conditions. It measures viscous, waxy, corrosive, and abrasive liquids to within ±1% maximum accuracy by separating liquids into equal portions and counting them. Liquid enters the meter through the inlet port, where the bridge deflects the liquid downward to strike the rotor blades and turn the rotor. The liquid then passes through the outlet port, which is aligned with the inlet port. Its BARTON Floco PD Meterrotor design also allows solid particles and sediment to pass through the meter without causing damage or malfunction. Bridge seals prevent the liquid from passing to the outlet port without being measured. 

Our BARTON Floco liquid PD meters are unique in that the more viscous the process fluid, the better the meter performance. High viscosities allow the meter to measure low flow rates with improved accuracy. Originally designed for raw crude oil production, our Floco Series F liquid PD meter has proven to be a versatile unit that performs easily in a broad range of high-viscosity fluids. Ideal for oils and grease, paints and coatings, and even paraffin, this meter also can be used to drive a proportional sampler to provide volume as well as product quality data. 

BARTON Flotrac Liquid PD Meter

Like other PD meters, the BARTON Flotrac liquid PD meter is designed to mechanically measure volumes of low-viscosity liquids flowing at high pressures. Our highly durable Flotrac liquid PD meter employs a unique feature – a constrained vortex principle that helps to provide an accurate measurement over a 10:1 range. Process liquid enters the metering chamber through the 1" inlet connection. As the liquid makes a 360-degree loop, it is separated equally into two streams. The special configuration of the metering chamber forces these streams into a series of vortices, causing the rotor assembly to rotate in direct proportion to the flow rate. The two liquid streams then are combined at the meter outlet port.
