42 Flow Level Pressure
Reliable Relief Valve and Flare Gas Flow or Leak Detection
Flow Meter with Live Demo Exhibited at OTC 2013
Visitors to OTC 2013, May 6-9, Houston, who stopped by Booth 8819 learned more about McCrometer’s (USA) advanced V- Cone Flow Meter, the ideal fluid measurement solution for rugged offshore production environments.
McCrometer’s exhibit at OTC featured a new flow demonstration unit. This live demo showed how the V-Cone Flow meter conditions flow unlike any other flow technology. Conditioning the flow in the pipe ensures accurate, reliable dP flow measurement in any environment.
With its unique differential pressure (dP) cone design, the versatile V-Cone Flow Meter and highly scalable Wafer-Cone Flow Meter provide superior flow measurement accuracy and repeatability regardless of space and weight constraints. McCrometer’s field-proven flow measurement solutions have met the demanding production environment of the oil and gas industry for more than three decades.
Petrochemical industry process and plant engineers searching for a precision flow/level/temperature switch for use in liquid, air, gas or for interface service will find the FLT93 Series FlexSwitch from Fluid Components International (USA) provides an effective and highly reliable solution in a wide range of applications.
Ideal for use in oil/gas upstream production or downstream refining, storage and distribution, the Fluid Components International (FCI) FLT93 Series FlexSwitch provides dependable relief valve monitoring and flare gas flow or leakage detection. The FLT93 Series FlexSwitch improves plant safety and environmental compliance by helping to assure operators that relief valves and flare gas systems are functioning properly.
FCI’s FLT93 Series FlexSwitch is the process industry’s most advanced heavy-duty thermal dispersion technology flow and level switch in the world. Its multi-parameter measurement design is based on more than 45 years of flow and level switch engineering and application experience, providing a rugged long-life instrument.
SIL2 rated for ultra-reliability, the FLT93 Series FlexSwitches are found in the world’s most demanding processes and plants. Ex agency approvals are provided for the entire instrument—FM, FMc, ATEX, IECEx and more. They are ideal for use in a wide range of oil and gas upstream and downstream applications as well as in other rugged industries with high reliability instrumentation requirements.
A dual-function instrument, the FLT93 Series FlexSwitch can be configured for flow or level sensing, flow + temperature sensing or level + temperature sensing. A single FLT measures and monitors flow or level and temperature simultaneously with excellent accuracy and reliability. Dual trip points and 6A relay outputs are standard and are assignable to flow, level or temperature.
FCI’s unique sensor technology of the FLT93 Series switches, combined with FlexSwitch temperature compensation circuitry, provide users with unparalleled performance capabilities: Exclusive flow accuracy as precise as ±2% of the setpoint velocity over ±50°F [±28°C] temperature range; repeatability of ±0.5% reading. Level resolution is ±0.1 inch [±2.5 mm]; repeatability of ±0.05 inch [±1.3 mm]. Standard temperature accuracy is ±2.0°F [±1°C]; repeatability ±1.0˚F [±0.6˚C]; improved temperature accuracy is available with factory calibration.
Two standard sensing element configurations are available to meet your most demanding application requirements. The FLT93 S is designed for use in standard heavy industrial applications and in applications with high velocity liquid setpoint requirements; the FLT93 F is designed for fast response gas applications. Both sensing elements can be supplied in either standard (-40 to 350°F [-40 to 177°C]) or medium (-100 to 500°F [-73 to 260°C]) temperature configurations. The FLT93 S is also available in a high temperature (-100 to 850°F [-73 to 454°C]) configuration.
A wide selection of standard and custom process connections can be provided. The electronic control circuit can be integrally-mounted with the sensing element, or it can be located in a remote location. The standard enclosure is a coated aluminium alloy. It can be used in ATEX locations and is rated for NEMA Type 4X (IP66) environments.

Third party testing to the American Petroleum Institute’s API 22.2 Testing Protocol for Differential Pressure Flow Devices confirms the V-Cone’s highly accurate flow measurement with minimal pipe runs. The V-Cone also is available with international certifications such as Measurement Canada, INMETRO, GOST and many others.
McCrometer’s V-Cone Flow Meter reduces the upstream/downstream straight pipe run required by Orifice Plates and Venturi Tubes by up to 70 percent. This significant reduction in pipe requirements adds up to cost savings in materials and installation labour that reduce FPSO Vessel tonnage and the footprint of Subsea modules. Using less pipe and reducing total weight also simplifies vessel balancing, making it easier to find the optimal location for flow meter installation.
The V-Cone provides a stable flow profile for reliable measurement, featuring accuracy of ±0.5% of actual flow and repeatability of ±0.1% over the entire range. It is ideal for the measurement of liquid, steam or gas and is available for line sizes from 0.5 to 150 inches, with an unmatched range-ability. Its no-moving-parts design provides an extremely rugged instrument.
Highly scalable, McCrometer’s Wafer-Cone Flow Meter is ideal for processes in line sizes from 1 to 6 inches for onshore well-head measurement, Oil Treating, Enhanced Oil Recovery, Coal Bed Methane, Coal Seam Gas and Oil Sands applications. It can be installed virtually anywhere in a piping system or be easily retrofit into an existing piping layout, resulting in significant installation flexibility and in new installation initial cost savings.
The Wafer-Cone Flow Meter achieves an accuracy of +1.0 percent, with a repeatability of +0.1 percent, and operates over a flow range of 10:1. The Wafer-Cone raises the bar for economy, ease of use and performance.

L&J Engineering (USA) is pleased to introduce all new MCG 8153 Flexible Magnetostrictive Level Gauge to its line of world class instrumentation.
The MCG 8153 Flexible Magnetostrictive Level Gauge is a highly accurate, continuous measurement device that is easy to install and maintain. In addition to measuring two levels (product and interface), five temperature sensors are embedded in the probe at different levels to provide average temperature measurement of the product. The MCG 8153 features a multi-protocol capable digital output to easily interface with both existing and new systems.
With flexible probes in lengths up to 70 feet, the MCG 8153 Gauge can be installed in nearly any type of storage or process vessel; aboveground or underground. Mounting options include an NPT or flange connection. The MCG 8153 can provide both level gauging data and act as a point switch for process vessels or overspill alarms.

Specifying the Optimal Liquid Flowmeter for Your Application
Drawing upon many years’ experience of designing and supplying liquid flowmeters to meet stringent OEM specifications - Titan Enterprises (UK) have produced an informative white paper 'How to specify liquid flowmeters'.
Accurate, reliable, cost effective flow measurement is more important today than it has ever been. However the optimal liquid flowmeter varies considerably according to a wide range of operational parameters including pipe bore, flow path, liquid viscosity, particulate levels, measurement accuracy, measurement dynamic range, maintenance and target purchase price.
In this 8-page white paper different styles of flowmeter (differential pressure, turbine, propeller, positive displacement, vortex, ultrasonic, electromagnetic and mass
flow measurement) are discussed and their ease of application, limitations and other constraints detailed. Summarising the author includes an easy-to-use selection guide that takes 13 application examples charting them against 14 different types of flowmeter, highlighting the good, the bad, and the questionable techniques for each application.
