Overview
The Deepflow CYPF05381 water level sensor is a precision capacitive-level sensing module engineered for integration into laboratory-scale ultra-pure water systems with a nominal tank capacity of 60 liters. Designed specifically for continuous, non-invasive monitoring of deionized (DI) or ultrapure water (UPW) levels in stainless steel or polypropylene reservoirs, this sensor operates on the principle of dielectric constant differential detection—leveraging the stark contrast between air (εr ≈ 1) and ultrapure water (εr ≈ 78.5 at 25 °C). Its compact, IP67-rated housing ensures reliable operation in humid, cleanroom-adjacent environments typical of ISO Class 5–7 laboratory water distribution zones. Unlike float-based or ultrasonic alternatives, the CYPF05381 eliminates mechanical wear, bubble interference, and temperature-induced drift—critical for maintaining uninterrupted water supply to downstream purification stages such as UV oxidation, TOC reduction, and 0.2 µm final filtration.
Key Features
- Capacitive sensing technology optimized for ultrapure water (resistivity ≥ 18.2 MΩ·cm), minimizing polarization effects and electrolytic noise
- Fixed-range calibration for 60 L cylindrical or rectangular tanks; configurable output signal (4–20 mA analog or 0–5 V DC) compatible with PLCs and SCADA interfaces
- Chemically inert PTFE-coated probe tip and 316L stainless steel mounting flange—resistant to leaching and corrosion in high-resistivity water
- Integrated temperature compensation circuitry (±0.1 °C resolution) to correct for density-driven permittivity shifts across 5–35 °C operating range
- Low-power consumption (≤1.2 W) enabling seamless integration into energy-conscious UPW system control panels
- EMI-hardened design compliant with IEC 61326-1 for electromagnetic compatibility in shared lab instrumentation racks
Sample Compatibility & Compliance
The CYPF05381 is validated for use with Type I ultrapure water per ISO 3696:1987 and ASTM D1193-20 Standard Specification for Reagent Water. It meets material compatibility requirements outlined in USP Total Organic Carbon and EP 2.2.44 Conductivity, ensuring no measurable ion release or particle shedding during prolonged immersion. While not certified to FDA 21 CFR Part 11 out-of-the-box, its analog output architecture supports traceable calibration logs when paired with compliant data acquisition systems meeting GLP/GMP audit trail requirements. The sensor is suitable for installation in Class A/B/C clean utility areas per EU GMP Annex 1 (2022), provided tank access ports comply with ASME BPE-2021 sanitary connection standards.
Software & Data Management
The CYPF05381 operates as a standalone field device without embedded firmware or cloud connectivity. Its analog output integrates directly into existing laboratory building management systems (BMS), programmable logic controllers (PLCs), or dedicated UPW system HMIs—such as those based on Siemens SIMATIC S7, Rockwell Automation CompactLogix, or LabVIEW-based custom dashboards. For audit-ready applications, users are advised to configure external data loggers with timestamped, write-protected storage and user-access controls aligned with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Calibration records—including zero/span verification against NIST-traceable liquid height standards—must be retained per ISO/IEC 17025:2017 clause 7.7.
Applications
- Real-time level feedback for feedwater reservoirs in dual-stage RO + EDI + UV ultrapure water generators
- Interlock triggering for pump shutdown or alarm activation upon low-level conditions in 60 L point-of-use (POU) storage tanks
- Process validation support during IQ/OQ/PQ protocols for water-for-injection (WFI) or purified water (PW) systems
- Integration into automated water quality monitoring loops where level data correlates with resistivity, TOC, and bacterial load trends
- Replacement sensor for legacy ultrapure water systems requiring RoHS-compliant, CE-marked components without redesigning tank penetrations
FAQ
Is the CYPF05381 suitable for pressurized water tanks?
No—it is rated for atmospheric or gravity-fed reservoirs only. Maximum working pressure: 0.1 MPa gauge. For pressurized applications, consult Deepflow’s CYPF-P series with welded diaphragm isolation.
Can it detect water conductivity changes or only level?
Level only. Capacitance-based measurement is insensitive to ionic concentration; however, consistent dielectric response requires stable water purity—significant organic contamination may reduce accuracy.
What is the recommended recalibration interval?
Annual verification is advised under GLP conditions; more frequent checks (e.g., quarterly) are recommended if tank cleaning cycles involve aggressive caustic or acid rinses.
Does it include mounting hardware for standard 1/2″ NPT or DIN 11851 ports?
Yes—the unit ships with a 316L stainless steel compression fitting kit compatible with both 1/2″ NPT and DIN 11851 Type A connections.
Is technical documentation available in English with metrological traceability statements?
Yes—Datasheet, Installation Manual, and Factory Calibration Certificate (with uncertainty budget per ISO/IEC 17025) are provided in English upon order confirmation.
