Sho-Rate Model 1250/1255 Low Flow Glass Tube Flowmeter
Brand: Brooks InstrumentFor 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
