FlowFit CYA27

Summary

Product Identification

Flowfit CYA27 is a modular flow assembly designed for multiparameter measurements, primarily in bypass installations.

Application Areas

• Drinking water
• Process water
• Saltwater
• Swimming pool water

Key Features and Benefits

• Flexibility: Modular design adaptable to process requirements, capable of measuring up to 6 parameters. Offers flexible installation for optimal sensor positioning.
• Minimum Water Loss: Requires a sample flow of only 5 l/h (1.32 gal/h) for precise measurement, minimizing water discard.
• Reliable Measurement: Integrated flow monitoring with LED indicators for correct flow rate and error detection.
• Easy Maintenance: Optional cleaning and dosing module enables automatic cleaning cycles.

Operating Principle

The CYA27 flow assembly facilitates reliable liquid analysis measurements for parameters including disinfection, pH, ORP, conductivity, and oxygen. Integrated flow measurement ensures safe and reliable operation.

Measuring System Components

A complete system can include up to six sensors and typically consists of:

• Flow assembly Flowfit CYA27
• At least one sensor (e.g., CCS51D for free chlorine, Memosens CPS31E for pH, Memosens CPS16E for ORP, CLS82E for conductivity, COS22E for oxygen)
• Measuring cable (e.g., CYK10)
• Transmitter (e.g., Liquiline CM44x or CM44xR, Liquiline Compact CM82)
• Optional accessories: Multiparameter handheld device, extension cables, sampling valves, flow switches, status lighting.

Operating Limits

• Ambient Temperature: -20 to 60 °C (-4 to 140 °F)
• Storage Temperature: -20 to 60 °C (-4 to 140 °F)
• Medium Temperature: 0 to 60 °C (32 to 140 °F), non-freezing. At temperatures below 0 °C (32 °F), the medium temperature must be at least 5 °C (41 °F) and lines insulated.
• Process Pressure: 0 to 4 bar (0 to 58 psi) relative
• pH Range: pH 1 to 12

Flow Rates

• Recommended flow range (5 l version): 5 to 8 l/h (1.32 to 2.11 gal/h)
• Recommended flow range (30 l version): 30 to 40 l/h (7.92 to 10.46 gal/h)
• Critical upper limit (5 l version): 40 l/h (10.56 gal/h)
• Critical upper limit (30 l version): 80 l/h (21.13 gal/h)

Mechanical and Hydraulic

• Mounting Orientation: Horizontal only.
• Process Connections: G 1/4" (ISO 228)
• Weight: Varies based on the number of modules, ranging from 0.9 kg (1.98 lb) for 1 module to 3.8 kg (8.38 lb) for 6 modules (without sensors). Wall mounting accessories weigh 1.3 kg (2.87 lb).
• Materials in contact with medium: PMMA (modules), PVDF (inlet/outlet), FPM (seals), PVC/POM or PVDF (plugs, adapters, valves), Titanium (floats), PVDF (flowmeter), Stainless Cr-Ni steel (equipotential bonding).
• Materials not in contact with medium: PBT-GF20/GF30.

Accessories

• Peristaltic Dosing Pump: Available for dosing liquid media, with volumes from 0.5 ml/h to 10000 ml/h. Kits are available for different flow ranges (0.1-22 ml/min and 1-200 ml/min) and maintenance.
• A variety of sensors for disinfection, pH, ORP, conductivity, and oxygen measurements are available, many featuring Memosens technology.
