Blancett B1500 Turbine Flow Meters (now Badger Meter) have exceptional mechanical linearity, resulting in minimizing, or negating, temperature induced viscosity influence. Meters come with national pipe thread (NPT) or flange process fittings, sizes up to two inches and can be ordered with a Blancett B3000 flow monitor for advanced linearization and to accommodate the requirements of most applications and flow ranges.
Features
- Expanded mechanical linearity
- Helical rotor design
- High-performance ceramic ball bearings
- 6-bladed rotor supports
- Facility with NIST traceable standards
Benefits
- Increased usable flow range with less sensitivity to fluid temperature/viscosity effects.
- Exceptional speed-of-response, with reduced pressure drop.
- Ceramic bearings provide near-perfect roundness, higher Rockwell hardness and are lighter and more tolerant to temperature than 440C stainless steel bearings. They eliminate adhesive wear and perform well in non-lubricating liquids found in cryogenic fluids and water.
- Improved flow conditioning.
- Third party audits to ensure calibration uncertainty. Laboratory correlation to verify that all calibrators produce the same result.
Operating Principle
As a fluid passes through the meter, the velocity of the fluid provides rotational energy on the rotor blade assembly. The rotor blades, passing through a magnetic field (produced by the pickoff), generate pulses proportional to flow. Each pulse is transmitted to the flow monitor, where the monitor calculates the flow relative to received pulses and meter size.
Applications
Blancett B1500 flow meters are the ideal solutions for standard clean, filtered liquid flow applications in precision industrial processes, found in the chemical/petrochemical, refining and general industries.
Calibration
Meters come with a best-in-class 10-point calibration, traceable to NIST standards, using calibration solvent.
Construction
Blancett B1500 flow meters feature 316 stainless steel housings. Wetted materials include axial helical rotors, made of 17-4 stainless steel, that rotate on ceramic ball bearings. The supports and all other materials are made from 300 series stainless steel.
Meter Installation
Blancett B1500 flow meters mount directly in the piping and can be installed in any position without affecting performance. For optimal performance, recalibrate the meter if the mounting orientation is changed from the original horizontal calibration.
To reduce flow turbulence, install a minimum of 10 diameters in length of straight piping upstream and a minimum of five pipe diameters downstream. If this cannot be accommodated due to space limitations, pay careful attention to the location of valves and bends. To compensate for piping bends, meters can be calibrated in the same piping configuration. For best performance and longevity, upstream filtration (10-75 micron, depending on meter size), is helpful to prevent bearing contamination and to avoid rotor blade damage.
