167360482 Union Diaphragm Valve Industrial Water Treatment PVC 150PSI Corrosion-Proof Valve

1. Precision Gas Flow Measurement Solution​

The GF Signet 167360482 Proline t-mass is a thermal mass flowmeter engineered for accurate gas monitoring in hygienic and industrial processes. Featuring ​direct mass flow measurement​ via ​constant temperature differential (ΔT) technology, this device delivers ​​±0.5% accuracy​ and ​​±0.1% repeatability​ across ​0.05–120 Nm/s flow ranges​ without pressure/temperature compensation. Its ​IP69K-rated 316L stainless steel housing​ meets ​EHEDG Type EL Class I​ standards with ​Ra≤0.4µm surface finish​ (ASME BPE-2022), withstanding ​150°C SIP cycles​ and ​100-bar CIP cleaning. The "0482" suffix denotes ​DN80 tri-clamp connection, ​4-20mA + HART 7.5 outputs, and ​SIL 2 compliance. Certified for ​​-40°C to +150°C operation, it incorporates ​auto-purge functionality​ and ​diagnostic intelligence​ for applications including bioreactor aeration, clean-in-place (CIP) gas verification, and inert gas blanketing. Integrated ​**Heartbeat Technology®**​ enables predictive maintenance alerts and automated validation.

​2. Critical Technical Specifications​

This flowmeter operates with ​18-36V DC power​ (≤5W) and measures ​0.05–120 Nm/s flow​ (±0.5% of reading + 0.1% FS). Key parameters include ​0.001 Nm/s resolution, ​​≤100ms response time, and ​5:1 turndown ratio. Sensor technology utilizes ​dual Pt1000 RTDs​ with ​ASIC-based temperature compensation. Materials: ​316L SS wetted parts​ (EP electropolished), ​PFA insulation, ​FFKM seals. Process connection: ​DN80 tri-clamp per DIN 32676​ with ​3° self-draining slope. Electrical isolation: ​1500V AC input-output​ with ​4kV surge protection. Communication: ​HART 7.5 / PROFIBUS PA / WirelessHART. Environmental: ​IP69K/NEMA 6P, ​15g shock resistance, ​5g vibration immunity​ (10–150Hz). Certifications: ​EHEDG EL-I, ​3-A 74-03, ​ATEX Zone 2/22, ​SIL 2 (PFHD 1×10⁻⁸/h)​. Dimensions: ​150×120×85mm​ with ​20-year MTBF​ at 80°C.

​3. Sanitary Gas Applications​

This flowmeter excels in critical gas monitoring:

• ​Bioreactor Aeration: O₂/CO₂ mass flow control (0.5–5 LPM)
• ​Pharmaceutical Purge: Nitrogen blanketing in lyophilizers
• ​CIP System Verification: Air knife flow validation
• ​Fermentation: Sterile air sparging rate control
• ​Packaging Lines: Modified atmosphere gas (MAP) dosing
• ​WFI Tank Blanketing: Nitrogen purity monitoring
• ​Sterilization: Ethylene oxide distribution
• ​Biogas Recovery: Landfill gas flow measurement
  Its tri-clamp connections enable rapid installation/cleaning validation in GMP environments. Thermal mass technology directly measures gas mass flow independent of pressure/temperature fluctuations - critical for cell culture processes where gas composition affects metabolic rates. SIL 2 certification supports safety instrumented functions for overpressure protection in bioreactors.

​4. Functional Advantages​

• ​Measurement Precision:
  Direct mass flow measurement eliminates compensation errors
  Auto-purge maintains accuracy during process interruptions
• ​Hygienic Design:
  Crevice-free flow path (Ra≤0.4µm) prevents biofilm growth
  EHEDG-certified cleanability with 3° drainage slope
• ​Diagnostic Intelligence:
  Heartbeat Technology® performs in-situ sensor verification
  Coating detection via thermal response analysis
• ​Validation Support:
  Automated as-built reports (GAMP 5 Annex 11)
  21 CFR Part 11 electronic audit trail
• ​Lifecycle Durability:
  No moving parts • 10-year calibration stability
  Gold-plated RTD contacts prevent oxidation
• ​Installation Flexibility:
  Bidirectional flow measurement
  Vertical/horizontal mounting without flow conditioning

​5. Smart Operation & Pharma 4.0 Integration​

​Measurement Principle​ utilizes ​constant ΔT technology: Two RTDs measure temperature differential - one heated sensor maintains constant ΔT above gas temperature, with power consumption proportional to mass flow. ​**Heartbeat Technology®**​ enables:

• ​Auto-Verification: In-situ performance validation without process interruption
• ​Predictive Diagnostics: RTD drift alerts • Coating accumulation monitoring
• ​Pharma 4.0 Integration: OPC UA/MQTT protocols for MES connectivity
  ​Safety Functions​ include ​SIL 2 overpressure protection​ via independent trip circuit and ​fail-safe 22mA output​ during critical faults. ​Smart Calibration​ features NIST-traceable certification with ​auto-zero function​ compensating for ambient changes. Predictive maintenance analyzes ​sensor response times​ to detect coating buildup >0.05mm before accuracy degradation. Compliance tools generate ​SEMI E142 formatted data​ for continuous process verification and automated validation packages with electronic signatures.
