True industry standards, Cameron's BARTON® Floco® and Flotrac® meters are staples in harsh environments that demand consistent, repeatable and rugged performance. Originally designed for raw crude oil production, the Floco F Series meter has proven itself 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, the Floco meter can also be used to drive a proportional sampler to provide volume as well as product quality data. The Flotrac meter is a highly durable unit that provides accurate, high-pressure measurement of low viscosity liquids.

Like positive displacement meters, the Flotrac meter is designed for mechanically measuring volumes of low-viscosity liquids flowing at high pressure. The Flotrac Meter employs the unique constrained vortex principle to provide an accurate measurement over a 10:1 range. Process liquid enters the metering chamber through the 1" (25 mm) 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 are then combined at the meter outlet port.

The Floco Series F meter is a positive displacement meter with a unique rotor design that provides sustained accuracy even under adverse conditions. It accurately measures viscous, waxy, corrosive and abrasive liquids to within ±1% maximum accuracy. The Series F meter measures liquid by separating it 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. The unique rotor design 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. Floco 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.

capacity of 6 to 90 USGPM based on 20° API gravity oil. Standard connections include 1-in. female and 2-in. or 3-in.male NPT threads. Raised face and ring joint flanges can also be supplied. Standard units for registering totals are US

gallons, 42-gallon barrels, liters, or cubic meters. Series F Meters are available with Buna-N, Viton®, or Teflon® components for compliance with process demands, and a long life between maintenance cycles.

A wide variety of liquids can be metered with the Series F meter, including heavy oil (25,000 centistokes max), asphalt emulsion, brine, bunker C oil, crude oil, kerosene, liquid fertilizers, paraffin, refined oils, and water. The Series F Meter does not require the installation of straightrun pipe upstream or downstream of the meter. The meter can be installed in any position and the register can be rotated in two planes for optimal visibility.

The Floco Sampler is an accessory to the Floco Model F-500 Meter that provides an efficient method of obtaining composite “proportion-to-flow” sampling. The sampler

indicates the flowing product quality, and is often used to determine the oil and water ratio (water cut) in a crude oil production facility. Accurate sampling is achieved by drawing fixed-size samples that are proportional to the net flow volume. Individual sample size and the sampling interval can be adjusted. The system is mechanically driven to ensure low installation cost and high reliability. To help assure accuracy, the sampler draws each sample from the middle of the flow stream. All samples are safely stored in a composite receptacle with a weight-actuated shut-off. The sampler assembly can be mounted to any Floco F-500 Meter in a horizontal (standard) or vertical (optional) pipeline. Vertical installations must be specified as flow-up or flow-down. Direction of flow (up or down) must be specified for vertical installations. When the orientation is properly specified, the sampler will shut off automatically when the receptacle is full. The sample bottle is vented to the atmosphere. To avoid exposing personnel to toxic vapors, never use the sampler in applications requiring NACE MR0175.

To summarize:

The Floco Automatic Sampler is an accessory to the Floco meter that provides proportional-to-flow sampling of fluids as they are metered. The sampler is used to determine the fluid quality which aids in determining:

• The ratio of oil and water being produced
• The ratio of dissolved gasses in heavy oil

The physical and chemical properties of the flowing fluid

The Floco Pulse Transmitter (FPT) adds a frequency output to a Floco Series F Meter. It is ideally suited for retrofitting in-situ meters to provide the necessary electronic output associated with an automation or SCADA project. The transmitter typically

consists of a gear-like target mounted within the magnetic field of a standard turbine flowmeter pick-up coil. As the teeth of the gear pass under the pick-up coil, an electronic pulse is generated in that the same way the movement of the rotor blades of a turbine meter generates a pulse. The FPT can generate up to 126 pulses per US gallon for any 1-in. or 2-in. Floco meter. The FPT can be installed easily and quickly without removing the meter from service. The transmitter mounts directly to the meter

body and can be used with or without a mechanical register. NuFlo MC series totalizers or frequency-2-4-20 mA converters are available to meet desired output signal requirements. For applications requiring a high amplitude 2-24 volt square wave signal, NuFlo offers an economical powered coil as an alternate. Electrical certifications are different for this alternate style. While the standard FPT is suitable for +250°F (+121°C), optional temperature ratings up to +450°F (+232°C) are available. Explosion-proof models feature a 1/2-in. FNPT electrical connection, while the intrinsically safe model has an optional 1-in. MNPT hub.
