Blancett Turbine Flow Meter Specifications

Turbine Flow Meter

Top Load 1 in. and 2 in. Meters

DESCRIPTION

The Top Load Turbine Flow Meter is designed to withstand the demands of the most rigorous flow measurement applications. Originally developed for the secondary oil recovery market, the Top Load Turbine Flow Meter is an ideal meter for liquid flow measurement on or off the oil field.

The meter features a rugged 316 stainless steel housing, rotor shaft and rotor support assemblies, C17-4 PH stainless steel rotor, and hybrid ceramic ball bearings. The meter maintains measurement accuracy and mechanical integrity in the corrosive and abrasive fluids commonly found in oil field water flood projects and many industrial applications.

When paired with a Blancett flow monitor, the meter meets a wide range of measurement requirements. This makes it ideal for applications such as pipelines, production and injection fields, mining operations, offshore facilities, and other industrial applications. For a full list of Blancett flow monitors, see www.badgermeter.com.

FEATURES

• Offers accurate and repeatable flow measurement in ranges from 5…225 gpm (18.9… 851.72 lpm)

• Cost-effective solution for turbine flow meter applications

• Rugged 316 stainless steel construction offers long service life in severe operating environments

• Available in NPT

• NIST-traceable calibration

• Installation in 1 in. and 2 in. pipe sizes

• Can integrate electronically with a Blancett flow monitor and K-factor Scaler, or the F-to-I/F-to-V Intelligent Converter

• Field replaceable repair kits allow for turbine replacement without loss of accuracy

• Can be repaired without removing the body from the line

INSTALLATION

The Top Load Turbine Flow Meter is simple to install and service. It operates in any orientation (horizontal to vertical) as long as the flow direction arrow is aligned in the same direction as the actual line flow. For optimum performance, the meter should be installed with a minimum of 10 diameters upstream straight pipe length and 5 diameters downstream straight pipe length.

REPAIR KITS

Designed for easy field service of a damaged turbine assembly, the repair kits replace only the internal parts, rather than replacing the entire meter.

Each repair kit assembly is factory calibrated to provide accuracy throughout the entire flow range. Each kit is complete and includes a new K-factor, which is the calibrated number of pulses generated by each gallon of liquid. Recalibration of the monitor or other electronics use the K-factor to provide accurate output data.

OPERATING PRINCIPLE

Fluid entering the meter passes through the inlet flow straightener which reduces its turbulent flow pattern and improves the fluid’s velocity profile. Fluid then passes through the turbine, causing it to rotate at a speed proportional to fluid velocity. As each turbine blade passes through the magnetic field at the base of the transducer, an AC voltage pulse is generated in the pickup coil. These pulses produce an output frequency proportional to the volumetric flow through the meter.

KFACTOR

The K-factor represents the number of output pulses transmitted per gallon of fluid passing through the turbine meter. Each turbine has a unique K-factor. However, turbine meters are not functionally consistent throughout the full flow range of the meter.

There are several forms of friction inherent in the turbine meters that retard the rotational movement of the turbine rotor. These frictional forces include: magnetic drag, created by electromagnetic forces of pickup transducers; mechanical drag, due to bearing friction; and viscous drag, produced by flowing fluid.

As flow increases, the frictional forces are minimized and the free-wheeling motion of the turbine rotor becomes more linear (proportional to flow). This is approximately a 15:1 turndown ratio from the maximum flow rate down to the minimum flow rate.
