Model 1200 In-Line Turbine Flowmeter

The Blancett Model 1200 in-line turbine flow meter was engineered for applications in highly corrosive environments. Developed for use in petrochemical and other process industries with liquid chemical flows, the Model 1200 turbine meter provides accuracy and durability in aggressive industrial environments. The meter features a 303 stainless steel body and internal wetted parts, with two type-440 stainless steel ball bearings.

The Model 1200 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 Model 1200 turbine meter meets a wide range of measurement requirements. This makes it ideal for
applications such as pipelines, production/injection fields, mining operations, offshore facilities, and other industrial applications. For a full list of Blancett flow monitors, see

More Details


The Model 1200 turbine meter is simple to install and service. It operates in a horizontal orientation with the flow direction arrow aligned in the same direction as the actual line flow. For optimum performance, install the flow meter with a minimum of 10 diameters upstream straight pipe length and 5 diameters downstream straight pipe length.


Fluid entering the meter passes through the inlet flow conditioner, which reduces its turbulent flow pattern and improves the fluid’s velocity profile. The fluid then passes through the turbine, causing the turbine to rotate at a speed proportional to the fluid velocity. As each turbine blade passes through the magnetic field, the blade generates an AC voltage pulse in the pickup coil at the base of the magnetic pickup (see Figure 1). These pulses produce an output frequency proportional to the volumetric flow through the meter. The output frequency represents the flow rate and/or totalization of fluid passing through the turbine flow meter.
