Sho-Rate Model 1250/1255 Low Flow Glass Tube Flowmeter

Brand: Brooks Instrument

For a wide range of chemical, petrochemical, biotechnology, research and analytical applications, Sho-Rate™ Series glass tube variable area flow meters provide industry-leading repeatability and reliability in two versatile lines.

Sho-Rate™ 1350/1355 flow meters deliver up to 3% accuracy and 0.25% repeatability depending on the model. Sho-Rate™ 1250/1255 flow meters offer a durable, cost-effective design to meet OEM requirements for systems requiring metering and analyzer integrators.
Features
  • Two accuracy levels: 5% Full Scale (Model 1250), 3% Full Scale (Model 1255)
  • Standard direct-read scales for common units and fluids – 65 mm, 150 mm scale lengths (approximate)
  • Inlet valve and outlet valve with options of cartridge valve, precision control valve or no valve
  • Easy-change design allows quick interchangeability of tube assemblies
  • Rotating lens provides a 180° view with magnification
Benefits
  • Options offer value-added features to meet project or OEM requirements
  • Borosilicate glass is resistant to thermal shock and corrosive gases and fluids
  • Corrosion-resistant material options for scales, floats, fittings and valves accommodate demanding applications
  • Integral float stops prevent loss of float during tube removal
  • Enhance accuracy with easy-to-read scales with magnification
  • Adjustable alarm guarantees safety and continuous process monitoring
