Overview
The Deepflow CYPF06805 is a precision liquid level sensing module engineered for integration into ultra-pure water (UPW) generation and distribution systems commonly deployed in pharmaceutical, biotechnology, and analytical laboratory environments. Designed specifically for 100-liter stainless-steel or polypropylene water reservoirs, this sensor operates on the principle of non-contact ultrasonic time-of-flight measurement—emitting high-frequency acoustic pulses (40 kHz typical) and calculating fill level based on echo return time. Its sealed, IP67-rated housing ensures resistance to condensation, ambient humidity, and incidental splashing, while its low-power analog output (4–20 mA two-wire loop) enables seamless compatibility with programmable logic controllers (PLCs), SCADA interfaces, and centralized water management platforms. Unlike float-based or capacitive alternatives, the CYPF06805 eliminates mechanical wear, contamination risk, and calibration drift associated with direct contact with ultrapure water—a critical requirement under ISO 3696 Grade 1 and ASTM D1193 Type I specifications.
Key Features
- Ultrasonic sensing technology with ±1.5 mm typical repeatability at 100 L capacity
- Stainless-steel mounting flange and PTFE-sealed transducer face compatible with USP Class VI materials
- 4–20 mA current loop output with HART® protocol support (optional firmware upgrade)
- Operating temperature range: 0–45 °C; maximum ambient humidity: 95% RH non-condensing
- Configurable damping (0–10 s) and zero/span adjustment via local potentiometers or remote digital interface
- Compliant with electromagnetic compatibility standards EN 61326-1 (industrial environment)
Sample Compatibility & Compliance
The CYPF06805 is validated for continuous monitoring of deionized (DI), reverse osmosis (RO), and ultrapure water streams meeting resistivity ≥18.2 MΩ·cm at 25 °C. It exhibits no leachable ions or particulate shedding—critical for maintaining TOC <1 ppb and silica <0.1 ppb performance targets in UPW loops. The sensor conforms to key regulatory expectations for water system instrumentation: it supports audit-ready documentation per FDA 21 CFR Part 11 when integrated with compliant data acquisition software, and its mechanical design aligns with ASME BPE-2022 surface finish requirements (Ra ≤ 0.4 µm) for wetted components. While not intrinsically safe, it is suitable for Zone 2/Class I Division 2 classified areas when installed per IEC 60079-14 guidelines.
Software & Data Management
The sensor interfaces natively with Deepflow’s AquaVision™ System Monitor Suite (v3.2+), enabling real-time level visualization, trend logging (minimum 1-second sampling interval), and alarm threshold configuration (e.g., low-level warning at 15% volume, pump interlock at 5%). All logged events—including sensor health diagnostics, signal strength metrics, and temperature-compensated output deviations—are timestamped and stored with GLP-compliant metadata (operator ID, instrument ID, calibration date). Export formats include CSV and XML, supporting import into LIMS platforms such as LabWare LIMS or Thermo Fisher SampleManager. Firmware updates are performed via USB-C port using signed binaries, ensuring traceability and integrity verification per NIST SP 800-193.
Applications
- Level monitoring in feed tanks and storage reservoirs of ultra-pure water systems (e.g., ELGA PURELAB, Sartorius arium®, Siemens PURELAB Quest)
- Interlock signaling for booster pump activation/deactivation to prevent dry-run conditions
- Volume reconciliation in batch preparation workflows requiring mass-balance validation (per USP )
- Integration into automated water-for-injection (WFI) validation protocols under EU Annex 1 and WHO TRS 970
- Redundant level verification alongside conductivity and TOC sensors in multi-parameter UPW quality assurance architectures
FAQ
Is the CYPF06805 suitable for pressurized water tanks?
No—it is rated for atmospheric or slight positive head pressure only (max. 0.1 bar gauge). For pressurized applications, consult Deepflow’s CYPF-P series with compensated diaphragm design.
Does it require periodic recalibration?
Field recalibration is not required under stable thermal and mounting conditions; however, annual verification against a certified depth gauge is recommended per ISO/IEC 17025 internal audit schedules.
Can it be used in hot water loops (e.g., >60 °C)?
No—the transducer electronics are rated to 45 °C ambient; elevated temperatures degrade piezoelectric element stability and void warranty.
What mounting orientation is supported?
Vertical installation only, with transducer face perpendicular to the water surface; angled or side-mounted configurations invalidate measurement accuracy.
Is third-party calibration certification available?
Yes—NIST-traceable calibration reports (including uncertainty budget per GUM) are provided upon request at additional cost and are valid for 12 months.
