Sho-Rate™ Glass Tube Flow Meters
Proven performance for low flow rates. Versatile options to match your needs.
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
- Flow Ranges:
- Air: Up to 140 scfh / 63 slpm
- Water: Up to 34 gph / 2000 cc/min
- Borosilicate glass tubes are compatible with most gases and fluids
- Float materials include black glass, 316 stainless steel, sapphire, Carboloy®, tantalum
- Magnification ensures scales are easy to read
Sho-Rate™ 1350 / 1355 / 1358 features include:
- Three accuracy levels: 3% (low-flow Model 1355), 5% (low-flow Model 1350) or standard accuracy of 10% (high-flow Model 1358)
- Repeatability of 0.25% Full Scale (0.5% Full Scale for Model 1358)
- Scale includes built-in magnifier – scale decals can be applied directly to the tube to support unique flow ranges and units of measure
- Optional standard or NRS™ integral needle control valves, as well as flow controllers on the inlet or outlet to go beyond measurement
- Integrated alarm option with single or double inductive ring sensor/switch with Intrinsically Safe Relay is ideal for hazardous environments
Sho-Rate™ 1250 / 1255 features include:
- 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
Applications
- Pharmaceutical production
- Research
- Chemical manufacturing
- Analytical instrumentation
- Water treatment and distribution systems
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
