BLANCETT
Frequently asked questions
Common questions about BLANCETT from 3G Electric.
What is the accuracy specification for Blancett B110 and B111 turbine flowmeters?
Blancett B110 and B111 series inline turbine flowmeters are specified with an accuracy of +/-1% of reading. This applies across the series, including models such as the B110-750, B110-875, B111-120, and B111-200. Accuracy is typically based on the meter being installed with the recommended straight pipe runs upstream and downstream, and with fluid viscosity within the meter's rated range. For critical applications, calibration certificates may be available; consult the product documentation for specific model calibration data.
What types of connections are available on Blancett inline turbine flowmeters?
Blancett inline turbine flowmeters are available with several connection types. The B110 series includes models with 1/2-inch NPT, 1-inch NPT, and 2-inch FNPT connections. The B111 series includes models with flange connections in sizes such as 6 inches and 10 inches. The B311-084 model has a 4-inch NPT connection. Connection type and size determine the maximum flow rate and pressure rating, so selection should be based on the piping system and required flow range.
What is the output signal from a Blancett turbine flowmeter?
Blancett turbine flowmeters provide a standard frequency pulse output. The pulse rate is proportional to the flow rate, and the meter generates a square-wave signal that can be received by flow monitors, rate/totalizers, PLCs, or flow computers. The pulse rate varies by model; for example, the B110-750 has a pulse rate of 3,300 pulses per unit volume. This output allows for remote totalization and rate indication without additional transmitters.
What fluids are Blancett B110 and B111 flowmeters suitable for?
Blancett B110 and B111 inline turbine flowmeters are designed for measuring oils and water. The stainless steel rotor provides compatibility with many petroleum-based fluids and water-based solutions. However, chemical compatibility should be verified for the specific fluid, temperature, and concentration. The meters are not intended for use with fluids that contain significant particulate matter or that are highly viscous, as these can affect accuracy and rotor operation. Consult the product data for pressure and temperature limits.
How do I select the correct Blancett turbine flowmeter for my application?
Selection of a Blancett turbine flowmeter involves matching the line size and connection type to the piping, and choosing a model with a flow range that covers the expected minimum and maximum flow rates. The B110 series with NPT or FNPT connections is used in smaller lines, while the B111 series with flange connections is used in larger lines. The minimum flow rate must be considered to ensure the meter operates within its specified accuracy. The pulse output must be compatible with the receiving instrumentation. 3G Electric lists the relevant specifications for each model to assist with selection.
What is the difference between the Blancett B110 and B111 series?
The Blancett B110 and B111 series are both inline turbine flowmeters for oils and water, but they differ primarily in connection type and size range. The B110 series includes models with NPT and FNPT connections, typically in sizes from 1/2 inch to 2 inches. The B111 series includes models with flange connections, such as 6-inch and 10-inch flanges, for larger line sizes. Both series provide a standard frequency pulse output and +/-1% accuracy. The choice between them depends on the piping system and flow range.
